Section 8: Plumbing System
Air Pressure Method
This method uses compressed air to blow out any remaining water in the system after ini-
tially draining water using drain valves. Tools required would be an air compressor and a
blowout plug.
1. Turn off the water heater gas valve typically
located outside the RV. Water heater power
should be OFF (turn off both ELECTRIC and
GAS switches).
2. Level the RV and drain the fresh water plumbing
system. (See Draining the Fresh Water System) .
3. Water heater bypass should be set to NORMAL.
This allows air to flow through the water heater.
If the drain plug is still in place, it should be
removed (as shown). Refer to the Water Heater
Bypass section.
4. RV water filter should be removed for winterizing (Refer to Water Purification System
section). Your RV may have a cartridge type water filter. Remove the cartridge filter
(if so equipped), and replace it with a bypass hose supplied with your RV. Antifreeze
should be kept out of the water filter.
5. Run the pump until it is dry (approximately 15 to 20 seconds). Operating the pump
longer than that with no water can damage the pump.
6. Open all faucets in the RV. If there is an outside shower, attach the shower hose to the
shower, and open the shower faucets.
7. Attach a blowout plug to the city water inlet on the outside of the RV. Refer to
Fresh
Water Connections .
8. Attach the air hose to the blowout plug. Set compressor to 30 PSI.
9. Fresh water tank drain should be open.
 Never apply air pressure to the water system with any of the valves in
the closed position. Air pressure applied to a closed valve, faucet or low
point drain could potentially damage the seals and cause water leaks. If
you have questions, consult with your RV dealer. Using RV antifreeze is
the preferred method of winterization.
 Recommended pressure is 30 PSI. Exceeding this pressure may rup-
ture water line couplings and void your warranty .
NOTE: Filters should be replaced at the beginning of the camping season
or if they have come into contact with contaminated water or antifreeze.
