SECTION 7
PLUMBING SYSTEMS
EXTERNAL WATER
SUPPLY (“City Water”)
To connect to an external source:
1. Turn the demand pump switch to OFF.
2. Attach a hose from the external water source
to the city water connection on the left side
of your vehicle.
3. Turn on the external water source.
When connected to an outside source of
water, the water bypasses the demand pump and
storage tank and supplies pressure directly to
individual faucets and toilet. A check valve built
into the pump prevents water from entering the
pump and filling the storage tank.
NOTE: Because city water pressure varies from
location to location, we recommend us-
ing an in-line water pressure regulator
to prevent damage to any components,
connections and seals in your fresh wa-
ter system. We recommend a regulator
that controls water pressure to 40 psi
maximum.
A water pressure regulator may be ob-
tained from any well stocked RV dealer-
ship retail center and some retail
discount centers. These devices simply
connect in-line between the supply hose
and the city water input on the coach.
To disconnect from the external source:
1. Turn the external source off.
2. Open a faucet inside the vehicle to relieve
line pressure.
3. Disconnect the hose from the vehicle and
replace the cap on the connection.
WATER DRAIN VALVES
The water drain valves are used to drain water
from the water tank and the water supply lines
when preparing the motor home for storage or
when sanitizing the water system. The water line
drain valves have teardrop shaped white handles.
The fresh water tank drain has a large yellow
handle. To drain the tank, move the handle so
that it is parallel to the drain pipe.
Model 22HD/22QD:
The drain valves are
located beneath the right rear dinette seat. They
can be accessed either by lifting the seat cushion
up or by removing the face panel from the
dinette seat base. The panel is held in place by
tube clips or hook-and-loop fasteners. Pull out-
ward gently and evenly to remove. Replace by
pressing panel gently back into position.
Model 22FD:
The drain valves are located
below an access hole beneath the bedboard of
the rear bed in the left (driver side) rear of the
coach. Lift or remove the bed mattress to expose
the access hole.
