Your RV should have low-point drains located at the lowest points of your plumbing system, typically under the sinks and in the water lines. Open these drains to allow any remaining water to escape. Place a bucket underneath to catch any water.
6. Opening Faucets and Showerheads
Open all faucets and showerheads throughout the RV. This helps ensure complete water drainage from the lines. Leave them open throughout the winterizing process.
7. Flushing the System with Antifreeze
Once the system is drained, connect your water hose to a city water hookup and begin flushing the system with RV antifreeze. Slowly pour the antifreeze into the water inlet. Make sure to open every faucet and showerhead again to ensure full circulation. Allow antifreeze to run through until you see it clear out of every faucet. The process ensures full coverage of antifreeze to protect the entire system.
8. Blowing Out the Lines with Compressed Air
After flushing with antifreeze, use your air compressor to blow out any remaining water. Connect your air chuck adapter to the city water inlet and turn on the air compressor to around 30 PSI. Keep a close eye on the pressure gauge and never exceed the recommended pressure for your system. You should hear hissing noises as the air pushes the water and antifreeze out of the system, a confirmation of successful air blowing process.
9. Thorough Air Blowing and Additional Considerations for Complete Winterization
While blowing out water lines with compressed air might seem straightforward, a thorough approach is key to preventing damage. Start with a low pressure (around 30 PSI), and slowly increase it as needed. Listen carefully for changes in the sound of air escaping the faucets – if the sound changes from a rushing water and air mixture to a consistent air sound, it indicates the pipes are mostly clear. However, ensure all faucets still have a steady stream of air coming out; this confirms that the air reaches all parts of the plumbing system. If not, carefully check for blockages or pinched hoses. Remember to disconnect the air compressor and close the low-point drains once the air blowing process is complete. Consider using a slightly higher air pressure (within the safe limit) if you have long or complex plumbing systems. Inspect all your water lines for any unusual wear and tear during winterization. Pay close attention to connections; ensure that there are no visible signs of leaks. Consider replacing worn-out parts before storing your RV. Pay attention to the toilet: flush the toilet several times to drain the bowl. Afterwards, add RV antifreeze directly into the bowl. Additionally, consider adding antifreeze to the trap. Some RV owners use compressed air on the toilet to force out remaining water. Always follow the manufacturer’s guidelines on maximum air pressure. The process ensures your RV’s plumbing system is completely winterized and ready for storage, preventing unexpected surprises when spring arrives.
10. Storing Your RV
Once winterized, store your RV in a protected area, if possible. Keeping it away from direct sunlight and extreme temperature fluctuations will further protect it during the winter months.
| Step | Action | Important Note |
|---|---|---|
| 1 | Drain Water Heater | Follow manufacturer’s instructions. |
| 2 | Bypass Water Pump | Open bypass valve if present. |
| 3 | Open Low-Point Drains | Place buckets to collect water. |
Efficiently Removing Water from RV Lines
Properly blowing out water from your RV’s plumbing system is crucial for preventing freeze damage during colder months. This process involves using compressed air to force water out of all lines, preventing expansion and potential bursting. Failure to do so can lead to costly repairs, impacting both your budget and the enjoyment of your RV. The process should be approached methodically and safely, ensuring all valves are correctly manipulated and pressure is carefully controlled to avoid damage. Utilizing the appropriate fittings and taking precautions against accidental disconnections are also vital aspects of successful winterization.
Before commencing, ensure you understand your RV’s plumbing layout. Locate all low points, faucets, and connections. Begin by turning off the water pump and draining the water heater tank according to its specific instructions. Then, open all faucets, including the low-point drains located at the lowest points of the plumbing system, to allow gravity to assist in the water removal process. This initial step significantly reduces the amount of water needing to be blown out with compressed air, minimizing the time and effort required.
Attach a compressor to a low-point drain, ensuring a secure and airtight connection using appropriate fittings. Start blowing air slowly and increase pressure gradually. Monitor all faucets and connections for any remaining water. The steady flow of air indicates successful water removal. If you notice resistance or water buildup in specific areas, check for clogs or improperly opened valves. Once all water is expelled, disconnect the compressor and secure all lines and connections to prevent accidental water re-entry.
People Also Ask: Blowing Water Out of RV Lines
What is the best way to blow out water from RV lines?
Using Compressed Air
The most effective method is using compressed air. Connect an air compressor to a low-point drain and gradually increase the air pressure to force the water out of the lines. Ensure all faucets and low-point drains are open to facilitate this process. Remember to use the correct fittings to avoid damage or leaks. Never exceed the manufacturer’s recommended air pressure for your system.
How do I know if all the water is out of my RV lines?
Monitoring Airflow and Pressure
Consistent, strong airflow from all open faucets and drains indicates a complete water removal. If you notice a drop in air pressure or a sputtering sound, it suggests water remains in the lines. Repeat the process, ensuring all valves are open and connections are secure. It’s advisable to check for any residual moisture by using an inspection camera if you feel unsure.
What happens if I don’t blow the water out of my RV lines?
Freeze Damage and Costly Repairs
Freezing water expands, potentially causing pipes and fittings to burst. This can lead to significant water damage within your RV, resulting in costly repairs including replacing damaged pipes, flooring, and potentially other components. Proper winterization, including blowing out water lines, protects your investment and ensures your RV is ready for the next season.
Can I use a shop vac to remove water from my RV lines?
Reverse Function and Limited Effectiveness
While a shop vac with a reverse function *can* be used, it’s generally less effective than compressed air. The suction power may not be sufficient to dislodge water from all lines, particularly those with minor clogs. Compressed air provides a more forceful and reliable method for thorough water removal.
