PLUMBING SYSTEMS
NOTE: Always keep the tank fill valve pointed to
"City Water" unless you are filling the
tank. If this valve is pointing to "Water
Tank Fill" while using city water, the
water will keep flowing into the tank and
out the tank vent tube.
Fresh Water Tank Capacity: 80 gal.

WATER PUMP

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 only when a fau-
cet is turned on and shut off soon after the faucet
is turned off. When you turn a faucet on, the
pump will begin to run and it will continue to run
as long as the faucet is open.
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 after a storage period or if
the tank and water lines have been drained.
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 used of the water pump
system. Thereafter, remember to check it
at least yearly, such as during winteriza-
tion procedures.
