Section 8: Plumbing System
The preferred method to winterize your recreation vehicle is by using RV antifreeze in the
plumbing system. It may be easier to winterize the RV with another person to assist you.
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). (Turn off power to the
tankless water heater)
2.
On the Uni-Doc utility center there are no water heater bypass valves.
3. Level the RV and drain the fresh water tank, tank (storage) water heater and hot & cold
water lines. Open all low point drains and fresh water tank drain. Open faucets inside
the RV to relieve pressure and allow lines to drain. Refer to Draining the Fresh Water
System section.
4. Remove the drain plug from the tank (storage)
water heater (Fig 1) (typically located outside
the RV). Do not remove the drain plug if the
water heater is hot or under pressure. Release
pressure & let it cool off.
5. To drain tankless water heater: open water fau-
cets, then use compressed air at the City Water
Connection on the utility center.

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.

If the recreation vehicle is going to be stored in a non-temperature controlled
environment with a risk of temperatures reaching 32°F (0°C) or lower, the air
pressure method is not adequate, winterizing with RV antifreeze
must
be used
in the plumbing system. Repairs due to freezing are not covered under the
terms of the
Towable Limited Warranty
.

Before applying air pressure to the utility center,
4 colored valves (WHITE,
RED, GREEN, BLUE)
MUST
be set to 45° or damage may occur to the util-
ity center
