Protecting your camper’s plumbing system from freeze damage during colder months is crucial for preserving its longevity and avoiding costly repairs. Neglecting this vital task can lead to burst pipes, significant water damage, and ultimately, a hefty repair bill. Therefore, understanding how to effectively blow out water lines is an essential skill for any RV or camper owner. This process, often referred to as winterizing, involves removing all water from the system using compressed air. While seemingly straightforward, improper execution can result in residual water remaining within the lines, rendering the process ineffective. Consequently, meticulous attention to detail is paramount to ensure complete water removal and prevent future problems. This comprehensive guide will meticulously walk you through each step, providing clear instructions and helpful tips to successfully winterize your camper’s plumbing, safeguarding your investment from the damaging effects of freezing temperatures. Furthermore, we will explore common mistakes to avoid, ensuring a smooth and efficient process.
First, you must completely drain your camper’s water tanks. This includes both the fresh water tank and the gray and black water holding tanks. Open all drain valves located at the bottom of these tanks, allowing gravity to do its work. Next, carefully open all faucets, both hot and cold, throughout the camper. This step is critical as it allows air to freely flow through the system, facilitating the complete expulsion of water. Simultaneously, flush the toilet to ensure complete drainage of the toilet bowl and its associated plumbing lines. Moreover, it’s advisable to disconnect any external water sources such as hoses connected to city water hookups. Remember, the goal is to create a pathway for air to displace all the water within the lines, preventing any water from becoming trapped. In addition to the faucets, be sure to open any low-point drains found under your sinks or near the water heater. These drains are specifically designed to aid in complete drainage and are often overlooked. Following this comprehensive draining process, inspect all drain valves to ensure they are completely closed to prevent any backflow during the air blowing process. This step prevents potential contamination and ensures the integrity of your system. Finally, before proceeding to the next stage, check all faucets again to confirm that no water drips are present.
Finally, after thoroughly draining your system, it’s time to introduce compressed air. Attach a compressor capable of delivering at least 30 PSI to the city water hookup. However, it is crucial to use a regulator to carefully control the air pressure. Excessive pressure can damage delicate plumbing components. Gradually introduce compressed air into the system, monitoring the pressure gauge closely. Listen for the telltale sound of air escaping from all faucets and low-point drains. This sound indicates the air is displacing the remaining water. Furthermore, continue this process until no more water is visibly present at any drain point. It is also essential to be patient; it may take several minutes to fully purge the system of all water. After ensuring all water is removed, disconnect the air compressor. As an added precaution, you can add RV antifreeze to all drains and low points to provide an extra layer of protection against any remaining moisture. This is especially crucial in areas with extremely cold winters. Subsequently, this multi-step process ensures your camper’s plumbing system is adequately prepared for the winter months, preventing costly repairs. Remember to always consult your camper’s owner’s manual for specific instructions and recommendations concerning winterizing procedures.
Assessing Your Camper’s Water System: Identifying Potential Freeze Points
Understanding Your Camper’s Plumbing
Before you even think about blowing out your lines, it’s crucial to understand your camper’s specific water system. This isn’t a one-size-fits-all situation; systems vary greatly depending on the camper’s age, make, and model. Take some time to familiarize yourself with its layout. Start by locating the main water shutoff valve. This valve controls the entire water supply to your camper and is usually located near where the water hose connects to the camper. Knowing its location is essential for both winterizing and regular maintenance.
Next, trace the water lines. Follow the path of the pipes from the inlet valve, noting where they run through the camper. Pay close attention to areas where pipes are exposed to the outside elements, such as under the camper or in less-insulated areas. These are prime candidates for freezing. Look for low-lying points in the system, since water tends to pool there and freeze first. Take note of any low points near the water heater, sinks, toilet, shower, and even your outside shower if applicable.
Many modern campers have PEX tubing, a flexible plastic pipe that’s resistant to freezing. However, even PEX can freeze under extreme conditions. Older campers might utilize other materials like copper or galvanized steel, which are more susceptible to freezing and potential damage. Identify the type of piping in your system as this will influence your winterizing strategy. You might find diagrams or schematics of your plumbing system in your owner’s manual, which will make this process significantly easier. If you can’t locate your manual online, consider reaching out to your camper’s manufacturer directly.
Identifying Potential Freeze Points
Once you’ve mapped your camper’s water system, focus on identifying the most vulnerable areas. These are typically places where water lines are exposed to colder temperatures or are poorly insulated. This often includes:
| Location | Why it’s vulnerable | Mitigation Strategy |
|---|---|---|
| Under the Camper | Exposed to the elements, minimal insulation | Add insulation, use heat tape |
| Exterior Faucets/Showers | Directly exposed to cold air | Disconnect and drain completely. Use insulated covers if leaving faucets in place. |
| Low-Lying Pipes | Water settles here, freezing first | Ensure proper drainage. |
| Water Heater Bypass Lines | Often overlooked, can contain standing water. | Ensure these lines are purged. |
| Areas with Limited Insulation | Poor insulation allows cold air to reach the pipes. | Add additional insulation to vulnerable areas. |
Remember, thorough identification of potential freeze points is paramount. The better you understand your camper’s plumbing, the more effective your winterization process will be, preventing costly repairs.
Preparing for the Blow-Out Process: Gathering Necessary Tools and Materials
Gathering Necessary Tools and Materials
Before you begin the process of blowing out your camper’s water lines, it’s crucial to gather all the necessary tools and materials. Having everything readily available will make the job smoother and more efficient, preventing frustrating delays. This preparation is key to ensuring a successful and safe winterization of your RV plumbing system.
Essential Tools
The core tools you’ll need are surprisingly straightforward. First, you’ll need an air compressor. The size depends on your system’s complexity and the length of your water lines; a smaller compressor might suffice for a compact camper, while a larger, more powerful model is recommended for larger RVs with extensive plumbing. Pay attention to the compressor’s CFM (cubic feet per minute) rating; a higher CFM allows for faster and more effective blowing. Always ensure your compressor is in good working order before you begin.
Next, you’ll need various adapters. Your compressor likely won’t connect directly to your camper’s water lines. You’ll need adapters to bridge the gap between the compressor’s output and the water system’s input. These often include a fitting that connects to the air compressor’s quick-connect fitting and then transitions to a garden hose connection. From there, you may require additional adapters to fit the specific type of faucet or valve connection in your camper. Having a selection of adapters on hand ensures compatibility regardless of your RV’s plumbing setup. It’s advisable to check your camper’s plumbing configuration beforehand to identify the necessary adapter types.
Finally, don’t forget the safety gear. Working with compressed air can be hazardous if proper precautions aren’t taken. Safety glasses will protect your eyes from debris or accidental splashes. Hearing protection is also strongly recommended, as air compressors can be quite loud. Additionally, consider using gloves to protect your hands from cold temperatures and potential damage.
Essential Materials
Beyond the tools, you’ll need a few essential materials. RV antifreeze is critical. This non-toxic solution protects your pipes from freezing and cracking. Ensure you purchase a non-toxic antifreeze specifically designed for RV systems. Never use automotive antifreeze, as it is toxic and can damage your system.
Having clean rags or towels is important for cleaning up any spills or drips. Lastly, you’ll want a bucket or container to collect any residual water. This can help prevent spills and keeps the work area clean and organized.

Locating and Accessing Your Camper’s Water Lines: A Step-by-Step Guide
Step 1: Identifying Your Camper’s Water System Components
Before you even think about blowing out your lines, familiarize yourself with your camper’s plumbing setup. This will save you time and frustration later. Typically, you’ll have a water pump (often located inside a cabinet), water inlet (usually on the outside of the camper, near a wheel well), and various pipes and fittings running throughout the camper. Locate your water pump – it’s usually a small, electric pump that pushes water from the tank or city water hookup to your faucets and fixtures. The water inlet is where you connect to an external water source, like a campground hookup. Finding these initial components gives you a head start on tracking the lines themselves.
Step 2: Tracing the Water Lines
With the major components located, it’s time to trace the water lines. This is easier in some campers than others, depending on the design and how accessible the plumbing is. Many RVs have easily accessible plumbing, often running along the walls, under cabinets, or within dedicated plumbing bays. Start by visually inspecting the areas where you found the pump and water inlet. Follow the pipes leading from these points. Often, pipes are color-coded (blue for cold, red for hot); however, this is not a universal standard, so careful visual inspection is critical. Some campers have removable panels or access doors which may reveal hidden sections of the plumbing. Be patient and methodical as you trace the lines, paying close attention to any fittings, valves, or connections you encounter.
Step 3: Detailed Access to Water Lines: Overcoming Obstacles and Techniques
Accessing your camper’s water lines may present certain challenges. Some lines might be tucked away behind walls, beneath flooring, or within difficult-to-reach areas. Don’t be discouraged; with a little patience and the right tools, you can gain access. First, consult your camper’s owner’s manual. It often includes diagrams of the plumbing system, highlighting access points and potentially revealing hidden panels. If your manual is unavailable, consider searching online for your specific camper model to find plumbing diagrams provided by other owners.
If you’re still struggling, don’t hesitate to use tools like a flashlight, a small mirror for hard-to-see areas, and even a thin, flexible probe to help you locate the lines. For hidden lines behind walls or under flooring, you may need to carefully remove panels or trim. Be incredibly careful when doing this—take pictures beforehand so you can accurately put the panels back. Use a putty knife or similar tool, working slowly and gently to avoid damaging your camper’s interior. If the lines are behind a wall, you might have to trace along the wall, locating screws or seams that might indicate access panels. Remember, safety should always be a priority. If you’re unsure about removing any panels or parts, consult with a professional RV technician.
Here’s a table summarizing common access challenges and solutions:
| Access Challenge | Solution |
|---|---|
| Lines hidden behind walls | Carefully remove wall panels (taking photos first), use a flexible probe to locate pipes. |
| Lines under flooring | Remove flooring sections (if possible and safe), using caution and taking photos before dismantling. |
| Lines in tight spaces | Use a small mirror or flashlight to get better visibility. |
| Unclear plumbing diagram | Search online forums or contact the manufacturer for assistance. |
Remember to always disconnect power and water before working on any part of your camper’s plumbing system.
Step 4: Preparing for Blow Out (covered in a subsequent section)
This section details the process of preparing your camper for the water line blow-out process itself (e.g., adding an air compressor, opening valves).
Purging the System: Removing Standing Water from Tanks and Lines
1. Preparing for the Blowout
Before you begin, gather your necessary supplies. This includes a compressor capable of delivering at least 30-40 PSI (check your camper’s manual for recommendations), a length of appropriately sized air hose (typically 1/4" or 3/8" inner diameter), several short lengths of tubing for adapting to your camper’s water fittings, and safety glasses. Ensure your camper is parked on a level surface and that the surrounding area is clear of any obstructions. It’s also helpful to have some towels handy to absorb any residual water that may escape during the process.
2. Locating Water System Access Points
Your camper’s water system will have several access points. These typically include the low-point drains (located at the lowest points of the water lines), faucets (both hot and cold), and water pump connections. Familiarize yourself with the location of these points before starting. Refer to your camper’s plumbing diagram if you have one. Taking photos before you start can also be incredibly helpful.
3. Draining Tanks and Low-Point Drains
Begin by opening all low-point drains. These are crucial for removing water that settles at the bottom of the lines. Then, drain all freshwater and gray water tanks completely. Most RVs have valves for this purpose; make sure they’re fully open. Allow ample time for gravity to do its work; several minutes may be required. Check the tanks occasionally to ensure they are completely empty.
4. Using Compressed Air to Blow Out Water Lines
Connecting the Air Compressor
Once the tanks are empty, connect your air compressor to the water pump inlet line. This is usually a fitting located near your water pump itself. If your setup doesn’t allow for direct connection to the pump inlet, consider connecting to a faucet via an appropriate adapter. However, use caution when connecting directly to the pump as some pumps don’t handle high PSI well and you risk damage to the pump’s internal parts.
Setting the Air Pressure
Carefully adjust the compressor to deliver approximately 30-40 PSI. Higher pressures could potentially damage your water lines or fittings, particularly in older systems. Always refer to your camper’s manufacturer’s instructions to determine the appropriate pressure. Your manual will indicate a maximum safe pressure. Never exceed this. Many modern RVs utilise a water filter before the pump which is also vulnerable to damage under high pressure.
Purging the System
With the compressor running at the correct PSI, systematically open each faucet, beginning with the ones furthest away from the compressor. Keep the faucets open until you hear a steady stream of air without any water escaping. This indicates that the water has been purged from that line. Repeat this process for every faucet and any other access points like the shower head, outdoor shower, and washing machine supply lines. It’s often helpful to work your way back toward the compressor, systematically clearing the lines. If a line is particularly stubborn, try disconnecting the tubing from its fitting before applying compressed air - sometimes removing the end fitting reduces resistance and allows air to more efficiently purge the line. Pay careful attention to the condition of your plumbing fittings and repair any damage as necessary.
Monitoring and Adjustment
Closely monitor the pressure gauge on the compressor and the output of air from each faucet. If the pressure drops significantly, it may be an indication of a blockage in the lines. If this happens, identify the source of the blockage, check for possible leaks and ensure your system is clear before restarting the process. This systematic process helps ensure all water is removed effectively. Take your time and do not rush this important step.
| Step | Action | Caution |
|---|---|---|
| 1 | Connect compressor to water pump inlet or faucet. | Check your camper’s manual for appropriate pressure. |
| 2 | Set pressure to 30-40 PSI (or as recommended by the manufacturer). | Never exceed the maximum safe pressure for your system. |
| 3 | Open faucets one by one, starting furthest from the compressor. | Listen for a steady stream of air. |
| 4 | Repeat for all faucets and access points. | Monitor the air pressure and check for blockages. |
5. Post-Blowout Inspection
After purging all the lines, disconnect the compressor and inspect all connections for any leaks. Wipe down any excess moisture. Leave all low-point drains open until you are ready to winterize your RV again. By performing the blowout process correctly you can effectively protect your RV’s plumbing system from damage caused by freezing temperatures.
Utilizing an Air Compressor: The Safe and Efficient Blow-Out Method
Preparing Your Camper for the Blow-Out
Before you even think about firing up the air compressor, proper preparation is key to a successful and damage-free winterization. Start by disconnecting your camper from any external water sources. This includes city water hookups and any hose connections. Next, fully drain all visible water tanks – fresh water, grey water, and black water. Open all faucets and low-point drains to ensure a complete emptying. This initial draining removes the bulk of the water, making the air compressor’s job much easier and reducing the risk of damaging your system due to trapped water.
Gathering Your Equipment
You’ll need a few essential items for this process. Obviously, an air compressor is the star of the show. Choose one with a regulator to control the air pressure; this prevents damaging your pipes with excessive force. You’ll also need various plumbing adapters to connect the compressor to your camper’s water lines. These adapters will vary depending on the type of fittings you have. It’s a good idea to have a collection of different sizes on hand. Finally, don’t forget safety glasses and ear protection; an air compressor can be noisy and potentially dangerous without the proper precautions.
Connecting the Air Compressor
Carefully connect the air compressor to your camper’s water system. Start at the lowest point in your water system, usually near the water pump. This allows the air to push the water out efficiently, rather than trapping it in various sections of the lines. Use the appropriate adapters to create a secure and leak-free connection. Take your time with this step; a poorly connected adapter is a major source of potential problems.
Setting the Air Pressure
This is where the regulator on your air compressor becomes invaluable. Avoid using excessive pressure; a gentle, steady flow of air is much more effective at clearing the lines than a forceful blast. Start with a lower pressure (around 30 PSI) and gradually increase it if needed. Observe the system closely for any leaks or unusual sounds. If you hear gurgling or sputtering sounds, there might be an air pocket that needs additional time to be cleared. High pressure is more likely to damage pipes and fittings.
The Blow-Out Process: A Detailed Look
With the compressor connected and the pressure set, slowly turn on the compressor. Monitor the air pressure closely to ensure it remains within a safe range. As air flows through the system, you’ll likely see water exiting from various faucets and low-point drains. This is normal and expected. Allow sufficient time for the air to thoroughly purge all water from the lines; rushing this step could leave residual water behind, leading to freezing and damage. The process is complete when only air comes out of all the outlets. Remember that different parts of the system might take longer to clear. For instance, longer lines, such as those leading to the showerhead, might require more time than shorter ones. You can use a small amount of compressed air to blow out lines that appear to be resistant. If you have any concerns about a particular area, take your time and don’t apply excessive pressure. You should observe the blow-out process and listen for any unusual sounds or indications of leaks throughout the procedure. Once the lines are free of water, you can then turn off the compressor and disconnect the tubing. Remember to always use caution when working with compressed air.
| Potential Problem | Solution |
|---|---|
| Water remains in a line after prolonged air blowing. | Check for blockages. Carefully use compressed air to free any obstructions, or consider using a plumbing snake. If the problem persists, professional assistance may be necessary. |
| Leaking fittings. | Turn off the compressor immediately. Tighten the fittings or replace them as needed. Ensure that all connections are secure before resuming. |
| Excessive noise or vibration. | Reduce the air pressure. Excessive noise or vibration indicates potential problems that should be addressed. Excessive pressure can damage the system. |
Storing Your Camper
After the blow-out is complete, it’s advisable to add RV antifreeze to all low points of the system to prevent any lingering moisture from freezing. Follow the antifreeze manufacturer’s instructions carefully. Proper storage is also vital to avoid water damage during winter.
Employing a Water Blow-Out Kit: A Streamlined Approach for Efficient Purging
Preparing Your Camper for the Blow-Out
Before you even think about connecting your blow-out kit, ensure your camper is ready. This means disconnecting your water pump – you don’t want to risk damaging it by back-feeding compressed air. Also, open all faucets – hot and cold – throughout your camper. This includes showerheads, sinks, and toilet valves (if applicable). Leaving any faucets closed can create pressure points, potentially damaging pipes or fittings. Finally, check your low-point drains. These are usually located underneath your camper and allow for complete drainage of water from the lines. Make sure they’re accessible and open to allow for complete water evacuation during the process.
Selecting the Right Blow-Out Kit
Not all blow-out kits are created equal. Consider the size and complexity of your RV’s plumbing system when making your selection. Kits with higher PSI ratings provide more forceful air pressure, ensuring complete water removal even from long or complex plumbing runs. Look for kits that include multiple adapters to accommodate various faucet sizes and types. Some kits also offer a pressure gauge, allowing you to monitor the air pressure during the blow-out process, helping you avoid over-pressurizing your system. Quality materials, such as durable hoses and fittings, will provide a longer lifespan for your kit.
Connecting the Blow-Out Kit
With your camper prepared, carefully connect the blow-out kit to your fresh water inlet. Make sure the connection is secure and airtight to prevent air leaks. The air compressor will usually be connected to the other end of the kit’s hose. Double-check all connections before proceeding to the next step. A poorly secured connection can cause a failure in the blow out process and potentially damage your plumbing.
Activating the Air Compressor
Follow the instructions provided with your specific air compressor. Gradually increase the air pressure, closely monitoring the gauge if your kit has one. Avoid sudden bursts of high pressure, as this could damage your plumbing. The goal is to achieve a consistent, yet controlled flow of air throughout your lines.
Monitoring the Blow-Out Process
As air flows through the system, you should see water exiting from all the opened faucets. The water flow will gradually diminish as the lines clear. It’s crucial to maintain a visual check on all faucets to ensure a consistent flow, indicating complete water evacuation. If a faucet stops dispensing water prematurely, it might indicate a blockage somewhere in the system. Investigate the potential blockage before proceeding.
Troubleshooting Common Issues During the Blow-Out Process (Detailed):
Several issues might arise during a water blow-out. A common problem is insufficient air pressure. This can result from a faulty air compressor, a leak in the blow-out kit’s hose or connections, or an obstruction within the plumbing system. Inspect all connections thoroughly for leaks; use soapy water to identify any escaping air. If a leak exists, tighten the connection or replace any damaged components. If your air compressor seems weak, ensure it’s correctly powered and properly maintained. If an obstruction blocks the lines, you might need to use a plumbing snake to clear it. This requires some technical know-how and is generally recommended to be handled by a professional plumber if you are uncomfortable working on your plumbing system.
Another frequent problem is water remaining in the lines even after extended blowing. This could be due to low air pressure (as previously mentioned) or the presence of air pockets in the lines. To address trapped air, try gently tapping or shaking the pipes while the air is flowing. Low spots in the plumbing lines may require additional attention, potentially requiring you to use a higher PSI setting (within the safe operating limit of your system) to force the water out. Finally, ensure all low-point drains are fully open to facilitate complete drainage. Sometimes, a small amount of residual moisture might remain, particularly in low points, but this is usually insignificant and shouldn’t cause freezing issues if your camper is properly winterized with antifreeze afterwards.
It’s always advisable to consult your camper’s owner’s manual for specific instructions related to your model and plumbing system. If you encounter persistent problems during the blow-out process, consider seeking assistance from a qualified RV technician who possesses expertise in camper plumbing and winterization.
| Problem | Possible Cause | Solution |
|---|---|---|
| Insufficient Air Pressure | Faulty compressor, leaks, blockages | Check compressor, inspect connections, clear blockages |
| Water Remaining in Lines | Low air pressure, air pockets, low points | Increase pressure (safely), tap/shake pipes, open low-point drains |
| Slow Water Drainage | Partially closed valves, clogged lines | Check all valves, potentially use a plumbing snake |
Disconnecting the Blow-Out Kit
Once the blow-out process is complete, carefully disconnect the blow-out kit from your fresh water inlet. Turn off the air compressor and store the kit properly. It’s a good practice to inspect the kit for any damage after each use.
Final Checks and Winterization
After the blow-out, perform a final visual check to ensure all faucets are dry. While the blow-out process effectively removes most water, it’s highly recommended to complete a thorough winterization process involving the use of RV antifreeze to protect your plumbing system from freezing temperatures. This final step ensures the longevity and protection of your camper’s water system.
Verifying Complete Drainage: Ensuring No Residual Water Remains in the System
Thorough Visual Inspection
Before even attempting to blow out your camper’s water lines, a thorough visual inspection is crucial. Start by locating all low points in your plumbing system. This includes the water pump, low points in the lines themselves (often under sinks or near the floor), and the drain valves at the lowest points of each water tank (gray, black, and fresh). Carefully examine these areas for any visible standing water. Look for moisture or dampness around fittings, connections, and pipes, as even small leaks can indicate residual water. Remember, even a small amount of water left behind can freeze and cause significant damage.
Utilizing Gravity: The First Step
Once you’ve visually checked, let gravity do its work. Open all faucets, shower heads, and drain valves completely. Allow several minutes for any remaining water to naturally drain. The slope of your camper plays a role here – ensure your camper is level or slightly tilted towards the drain outlets. This simple step can often eliminate a surprising amount of residual water before you even begin using compressed air. If you have a water heater, remember to drain it separately, consulting your owner’s manual for specific instructions.
Employing Compressed Air: The Safe and Effective Method
Compressed air is the most effective way to clear remaining water from your RV’s plumbing system. However, safety is paramount. Never exceed the maximum pressure rating of your system or use overly high pressure. Using too much pressure can cause damage to your pipes or fittings. Start with lower pressure and gradually increase it if needed. Before you start, remember to turn off your water pump. Using an air compressor specifically designed for RV blowouts is ideal; these usually have pressure regulators to help you control the pressure levels carefully.
Safe Air Pressure Levels
The appropriate pressure depends on your specific system and materials, but a general guideline is to start low – around 30 PSI – and gradually increase it as needed. Observe your system closely for any signs of leaks or distress. If you notice any abnormalities, immediately stop the process and investigate.
| Pipe Material | Recommended Maximum PSI | Notes |
|---|---|---|
| PEX | 60 PSI | Very flexible and can handle slightly higher pressure; always check manufacturer recommendations. |
| CPVC | 50 PSI | Less flexible than PEX; avoid exceeding the recommended pressure. |
| ABS | 40 PSI | More brittle than PEX and CPVC; exercise caution and use low pressure. |
Post-Air Blowout Inspection
After using compressed air, once again conduct a thorough visual inspection. Check all faucets, showerheads, and low points for any signs of remaining water. Listen carefully for any unusual sounds – gurgling or hissing – that might indicate trapped air or water. If you find any lingering moisture, repeat the process or consider alternative methods, such as using a shop vac on the low points to remove the final traces of moisture.
Proactive Measures: Preventing Future Issues
To minimize future problems, develop a routine winterization strategy. Completely drain your water system before storing your camper for any extended period, particularly during freezing temperatures. Use RV antifreeze to protect your pipes from freezing damage. Regular inspection of your plumbing system for leaks or cracks can prevent future problems, ensuring that you are prepared to deal with any issues early.
Protecting Your Camper’s Plumbing: Winterization Best Practices Beyond Blow-Out
1. Understanding the Risks of Frozen Pipes
Frozen water expands, exerting tremendous pressure on your camper’s plumbing system. This pressure can cause pipes to crack, fittings to burst, and ultimately lead to costly repairs. Preventing freezing is crucial for protecting your investment and ensuring your camper is ready for use in the spring.
2. The Importance of a Thorough Blow-Out
A compressed air blow-out is a vital first step. It removes most of the water from your lines, minimizing the risk of expansion damage. However, residual moisture often lingers, particularly in low-lying areas or difficult-to-reach sections of the plumbing.
3. Beyond the Blow-Out: Anti-Freeze Solutions
While a blow-out significantly reduces the water volume, using RV antifreeze provides an added layer of protection. This non-toxic solution lowers the freezing point of any remaining water, preventing ice formation and damage. Always follow the manufacturer’s instructions for proper usage and disposal.
4. Proper Antifreeze Application
Introduce RV antifreeze through all faucets, showerheads, and toilet flush mechanisms. Allow the antifreeze to completely displace any remaining water in the system. You can use a mixture of air and antifreeze for a more efficient process, pushing the antifreeze through the lines using an air compressor. Ensure all water lines are flushed adequately and all faucets are left open, draining antifreeze into the holding tanks.
5. Low-Point Drains: Don’t Forget Them
Many RVs have low-point drains designed to completely empty the water from the plumbing system. Locate these drains and fully open them to allow any remaining water to drain. Ensure they are protected from freezing as well.
6. Protecting the Water Heater
Your water heater is particularly vulnerable to freeze damage. Completely drain the water heater according to the manufacturer’s instructions. Many units have a drain valve specifically for this purpose. This is usually located at the bottom of the water heater tank. It’s an essential step not to be overlooked
7. Insulation: An Added Layer of Protection
Insulating exposed pipes and water tanks provides an extra layer of protection against freezing temperatures. Use insulating sleeves or foam insulation to wrap exposed plumbing. This is especially important for RVs stored in areas with prolonged periods of sub-freezing temperatures.
8. Detailed Approach to Water Line Blow-Out and Antifreeze Treatment
A successful winterization process goes beyond a simple blow-out. Begin by disconnecting the water pump and turning off the water heater. Next, completely drain all fresh water tanks. Now, use a compressor to blow out the lines. Connect an air compressor to the lowest point of your system, typically a water faucet, then turn on the compressor to push air throughout the lines. It may help to open several faucets simultaneously. Pay close attention to low-lying points and areas that seem resistant to complete air purging. Once the blow-out is complete, proceed to the antifreeze treatment. Begin by pouring RV antifreeze into each faucet and shower head. Turn the faucets on and run them until only pink antifreeze is coming out. Repeat this for every water fixture throughout the RV. This process ensures the complete displacement of water. For tanks and water heaters, follow the manufacturer’s instructions for adding antifreeze to these areas. After completing these steps, make sure all low point drains are opened to ensure the proper flow of antifreeze. Don’t forget to open the toilet tank and add enough antifreeze to prevent freezing in the bowl and internal plumbing. Leaving faucets and drains open will further reduce risk. Remember, this is a precautionary measure; thorough treatment is key.
9. Post-Winterization Inspection
Before storing your RV for the winter, conduct a final inspection to ensure all steps have been followed correctly. Check for any leaks or signs of damage.
| Step | Description | Importance |
|---|---|---|
| Drain Fresh Water Tanks | Completely empty all fresh water tanks to prevent freezing and bacterial growth. | Essential for preventing damage and maintaining hygiene |
| Disconnect Water Pump | Prevents damage to the pump from freezing. | Prevents costly repairs |
| By-pass Water Heater | Allows complete drainage and prevents water heater damage. | Prevents costly repairs |
Troubleshooting Common Issues: Addressing Potential Problems During the Blow-Out Process
9. Dealing with Stubborn Airlocks and Slow Drainage
One of the most frustrating aspects of blowing out water lines is encountering airlocks – those pesky pockets of air that prevent water from completely draining. These airlocks can occur in low points in the plumbing system, bends in pipes, or within appliances like faucets and toilets. If you notice that the process is taking unusually long, or that certain areas aren’t draining effectively, you’re likely dealing with an airlock.
Several techniques can help dislodge these stubborn air pockets. Firstly, gravity is your friend. If possible, park your camper on a slope, with the low point of the plumbing system angled downwards. This allows gravity to assist in pushing the air out. Additionally, consider opening all faucets and low-point drains simultaneously. This helps equalize pressure throughout the system, making it easier for air to escape.
For particularly persistent airlocks, you might need to resort to more active measures. Gentle tapping or shaking of pipes can help dislodge trapped air. Use a rubber mallet or your hand to apply light taps along the suspected areas. Avoid excessive force to prevent damage. Alternatively, you can try using compressed air in short bursts rather than a continuous stream. The short bursts create pressure waves that can help move the air. Remember to always protect your air compressor’s nozzle from contact with the pipes to avoid damaging the fittings.
If you’re still encountering problems, check your low-point drains. Ensure they are fully open and clear of debris. Sometimes a small obstruction can prevent air from escaping and water from draining effectively. Consider using a small brush or compressed air to clear any blockages. Lastly, inspect all your fittings for leaks. While blowing out the system you may see some moisture coming from joints. If it is a significant leak, you’ll need to address the issue promptly. It’s always a good idea to winterize even if a small leak exists because even minor cracks can freeze and expand causing major problems in freezing temperatures.
Here’s a table summarizing troubleshooting steps for airlocks:
| Problem | Solution |

Proper Procedure for Blowing Out Camper Water Lines
Protecting your RV’s plumbing system from freeze damage is crucial, especially during colder months. Blowing out water lines is a highly effective method to prevent costly repairs. This process involves using compressed air to force all water out of the lines, preventing expansion and potential bursting when temperatures drop below freezing. Proper execution requires attention to detail and adherence to safety precautions. Before commencing, ensure the water pump is turned off and all water valves are closed. Begin by connecting an air compressor with a pressure regulator to a low-point drain or faucet. Gradually increase the air pressure, carefully monitoring the process to prevent excessive pressure that could damage the system. Once all visible water is expelled, it’s crucial to verify complete drainage by checking all faucets and low-point drains. Remember that this method isn’t a guarantee against freezing in extreme conditions, and additional measures like antifreeze may be necessary depending on the climate.
It is important to use a regulated air compressor to avoid exceeding the pressure tolerances of your camper’s plumbing system. Over-pressurization can result in damaged pipes or fittings. Always start with low pressure and gradually increase it as needed. Furthermore, ensure the air compressor is clean and free from moisture to prevent contamination of the plumbing system. After blowing out the lines, it’s recommended to leave all faucets slightly ajar to allow for any residual moisture to escape. Regularly inspecting your system for any leaks or damage after this process is also essential for maintaining the integrity of your RV’s plumbing.
While blowing out water lines is a relatively straightforward process, it’s advisable to consult your RV’s owner’s manual for specific instructions and recommendations. The manual may provide details about pressure limits, specific access points, and other relevant information particular to your model. If you are unsure about any aspect of this procedure, seeking professional assistance from an RV service technician is always the safest course of action. Improper execution could lead to damage to your plumbing system and potentially void any warranties.

How much air pressure should I use to blow out my camper water lines?
Recommended Air Pressure
The optimal air pressure for blowing out camper water lines varies depending on the system’s construction and materials. However, a general guideline is to start with low pressure (around 30 PSI) and gradually increase it as needed, carefully monitoring for any signs of leaks or stress on the plumbing. Never exceed the maximum pressure rating specified in your RV’s owner’s manual. Exceeding this could lead to damage to your plumbing and fittings. It’s often better to err on the side of caution and use less pressure for a longer duration than risk damaging your system with excessive force.
What happens if I blow out my camper water lines incorrectly?
Consequences of Improper Blow-Out
Incorrectly blowing out your camper water lines can lead to several undesirable consequences. Over-pressurization is a major concern, potentially causing pipes or fittings to burst or leak. Using excessively high air pressure may also damage the water pump or other related components. Conversely, insufficient pressure may not fully remove all water from the lines, leaving residual moisture susceptible to freezing. In any case, improper technique can lead to costly repairs and potentially render your water system unusable until the damage is addressed.
Can I use a shop air compressor to blow out my camper water lines?
Using a Shop Air Compressor
Yes, you can typically use a shop air compressor to blow out your camper water lines, but it’s crucial to exercise caution and use a pressure regulator. A pressure regulator allows you to precisely control the air pressure output, preventing accidental over-pressurization. Moreover, ensure the air compressor is clean and dry to avoid introducing contaminants into your water lines. Before connecting the compressor, make sure you understand the pressure limits of your RV’s plumbing system to prevent damage. If unsure, consult a qualified RV technician.
Do I need to use antifreeze when blowing out water lines?
Antifreeze and Blow-Out
While blowing out water lines effectively removes most water, using antifreeze is a supplementary measure, especially in extremely cold climates or if you aren’t completely confident in the thoroughness of your blow-out. Antifreeze offers an extra layer of protection against freezing, helping prevent damage should some residual water remain. However, it’s crucial to use RV-specific antifreeze, as other types can damage your plumbing system. Always follow the antifreeze manufacturer’s instructions for proper mixing ratios and application.
