Section 8: Plumbing System
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.
Red, Blue,
Green & White Valves must be set to 45° be-
fore applying air pressure 30 PSI Max. (Fig 2
).
There is no drain plug.
6.
Water filter should be removed for winterizing. See Water
Purification System section. Your RV may have one of two
types of filters:
Full System Canister Filter:
On full system canister water
filters remove the canister, take out the filter, and re-attach the
empty canister.
Cartridge Water Filter:
Remove the cartridge filter, and re
-
place it with a bypass hose that is supplied with your RV.
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.
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 utility center.
