Section 8: Plumbing System
112
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.
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 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 rup-
ture water line couplings and void your warranty
.
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!
An-
tifreeze should be kept out of the water heater.
