Section 8: Plumbing System
110
The preferred method to winterize your recreation vehicle is by using RV antifreeze in the
plumbing system.
Air Pressure Method
This method uses compressed air to blow out any remaining water in the system after
initially 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 OFF which will
allow 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 those supplied with your RV. Antifreeze should be kept out of
the water filter.
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
rupture 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.
Water heater drain plug location
NOTE:
:
The water heater must be drained to prevent
damage from freezing.
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.
