Your GMC MotorHome is equipped with its
own self-contained water system (figure 1) . The wa-
ter tank and pressure pumps are located at the right
rear corner of the MotorHome. The water pump
switch is located near the entrance door .
The living area water system is supplied by either
a demand water pump or by a city-water hook-up.
There is no pressure tank in the system . Water pres
sure is maintained by a 12-volt water pump which is
designed to automatically maintain enough pressure
to ensure a steady water flow .
A pressure switch is located at the water pump
to maintain line pressure between 15 psi. and 30 psi.
IMPORTANT: Do not attempt to increase water
pressure with high pressure air. Be sure the wa-
ter pump is turned "OFF" when the water tank
is empty .
A 40 gallon water tank stores water to be drawn
out by the water pump . The tank can be filled only
through its own fill tube connection, located either
inside the LP gas storage compartment at the right
GENERAL DESCRIPTION
rear corner of the vehicle or outside at the left rear
side of vehicle.

cle. There are seven drain valves on vehicles
