    VIAIR’s convenient and easy do-it-yourself winterization kit protects your RV’s water system from freezing during the long winter months, and helps avoid costly springtime repairs from damaged water lines due to winter freezes.

    – 1/4” Quick Connect Coupler
    – 1/4” Quick Connect Stud
    – Blow Out Plug
    – Regulator
    – 220 PSI gauge

    Instructions:

    Blow Out the System w/Compressed Air

     1. Disconnect from outside water source.

     2. Turn off all power and shut off propane.

     3. Bypass your water heater.

     4. Open all faucets.

     5. Open the system drain valves letting the water empty.

     6. Flush the toilet to clear any water from the line.

     7. Connect the “blow out plug” to the city water inlet—not the fresh water tank.

     8. Adjust the regulator to no more than 30 psi. (This helps avoid damaging the water lines.)

     9. Connect the blow out plug to the female quick connect coupler on the regulator.

    10. Turn on the compressor and let it run until all water is blown from the faucets and drain valves.

    11. Shut off the air compressor and disconnect the blow out plug from the water inlet.
