WATER PUMP
Water Pump
in right front compartment
When your coach is not connected to a city
water supply, water is supplied from the fresh
water tank by a water system demand pump.
A demand pump is designed to run when there
is no water line pressure backup against the
pump. This is what happens when you turn a fau-
cet on - the water line pressure drops and the
pump begins to run, and it will continue to run as
long as the faucet is open. When you turn the fau-
cet off, the line pressure backs up to the pump,
and it shuts itself off.
The pump is self-priming and will run briefly
to build up line pressure when the Water Pump
Switch is first turned on. See "Initial Water Line
Priming" for instructions on using the water sys-
tem for the first time.

Pump Strainer Filter
The pump is equipped with a cleanable strain-
er filter to capture any possible tank borne parti-
cles that could damage pump components.
Note: We recommend that you check and clean
this filter after each tankful of water dur-
ing the first few uses of the water pump
system. Thereafter, remember to check it
at least yearly, such as during winteriza-
tion procedures.
Push cover in firmly and
twist to remove and clean strainer
To Clean Pump Strainer
•
Press the inlet cap in towards the pump and
twist counterclockwise about 1/4 turn to dis-
engage from locking tabs.
•
Remove the cap, then pull the strainer screen
out of the bowl to tap out any particles and
rinse clean.
•
Insert the strainer screen back into the bowl,
then twist the cap back onto the bowl assem-
bly to close.
Water Pump Switch
The water pump switch is located on the
systems monitor panel (See Section 8). While
the switch is in the "ON" position, the pump will
automatically supply water pressure as it is need-
ed. It is recommended that the pump switch be
turned off whenever you are away from the
vehicle or not using the water system. A slow
leak in a faucet could drain the water system and
discharge the coach battery.
