Section 8: Plumbing System
NOTE: The winterization process may vary slightly due to different plumb-
ing configurations between models.
NOTE: Appliances must be winterized. Refer to the manufacturer's
manual for possible additional information or contact Customer Service for
assistance.
If you chose to perform the winterization process yourself, read and understand the follow-
ing information before starting. Contact customer service or your dealer for questions about
this process. It may be easier to winterize the RV with another person to assist you.
The preferred method to winterize your recreation vehicle is by using RV antifreeze in the
plumbing system.
NOTE: The water heater must be drained to prevent damage from freez-
ing. It is recommended the water heater be drained and bypassed during
the winterization process particularly if introducing RV antifreeze into the
plumbing system. Do not drain the water heater while it is hot or
under pressure! Antifreeze should be kept out of the water heater.
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.
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.
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.
