How To Blow Out Water Lines in RV With Air Compressor

Step 1 – Drain The Tanks & Water Lines

Before you can effectively blow out the water lines in your RV, it is crucial to ensure that all tanks are completely drained and all water lines are emptied. To achieve this, begin by turning off all faucets and thoroughly draining the fresh tanks. Next, open up each drain individually to meticulously remove any remaining water. Taking these meticulous steps will help guarantee that no water is left behind, ensuring a successful blowout of the water lines in your RV.

Drain The Tanks & Water Lines

Step 2 – Setting Up Your Air Compressor

Once you have double-checked that all tanks and water lines are completely drained, it is time to begin setting up your air compressor. To ensure efficient use of the compressor, make sure that there is no excess moisture in the airline. If necessary, you can add a small amount of oil to the air intake to help lubricate the piston assembly. Additionally, be sure to check that the size of the air pressure hose is compatible with your RV’s water lines.

Step 3 – Using The Air Compressor

With the compressor properly setup and ready to go, attach one end of the airline to the RV’s main water outlet. Once connected, bring up the compressor to its maximum PSI and release the air pressure into the water lines of your RV. The pressurized air will force any residual moisture out of the system, ensuring that no remaining water is left behind. Once you are done, disconnect the compressor and turn off all power sources.

Step 4 – Winterizing & Storing Your RV

After blowing out your RV’s water lines, it is crucial to winterize and correctly store your RV. Begin by adding antifreeze to the water lines and all tanks of your RV. This will help protect against any potential damage caused by freezing temperatures during the winter season. Additionally, be sure to disconnect any power sources before storage and double-check that all necessary doors are properly closed and sealed. Follow these steps and your RV will be healthy and safe until the next time it is used [3].
