Section 8: Plumbing System
NOTE: This method of filling the water tank is NOT recommended if
filtered water is required. However, if you fill the tank with unfiltered water,
all water from the fresh water tank goes through the whole house canister
filter. So as long as you have a water filter in the canister you will end up
with filtered water. The only method to fill the fresh water tank with filtered
water is by using the fresh water connection inlet and the city water / tank
fill valve on the docking (utility) center panel.
12-volt Water Pump and Water Pump Switches
Your motor home is equipped with water pump switches located on the Vegatouch screen
and the exterior monitor panel. Either switch will control the water pump.
Once activated, the water pump will self-prime, and provide water. The water pump contin-
ues to run until maximum pressure is achieved and shut off. The water pump will automati-
cally re-start when it senses a drop in the water pressure.
Some cycling may occur, depending on the volume of water being released. The water
pump is engineered with a check valve to prevent water from back flowing into the fresh
water supply tank.
When you want to use water in your motor home and it is not hooked up to city water, you
will need sufficient 12-volt DC power to run the water pump.
NOTE: The water pump switches should be in the OFF position when
the motor home is left unattended for any amount of time.
Maintenance
Normal pump maintenance consists of checking and cleaning of the strainer, normal sani-
tizing and winterizing and occasionally checking all plumbing hardware and fittings for
tightness.
Lack of sanitizing can lead to premature pump failure and poor performance over time.
Scale build-up on the diaphragm and valves, can cause low flow and leak back (occasional
pump cycling with no faucets open or tank filling up when hooked up to city water).
For more information, refer to the water pump manufacturer's user guide.
Water Purification System (if so equipped)
Primary water filter: The canister filter is the primary filter used for the complete water
system. It is located at the docking (utility) center of the motor home. If the water supply
has not been used for some time, allow the water to flow for several minutes to flush the
system.
NOTE: When not in use, the water filter cartridge should be stored out of
freezing temperatures. RV antifreeze will damage the water filter cartridge.
