Section 8: Plumbing System
12-volt Water Pump
There must be sufficient 12-volt DC power to run
the water pump when your recreation vehicle is not
hooked up to city water. Once activated, the water
pump (also known as the demand pump) will self-
prime, and provide water. The water pump continues
to run until maximum pressure is achieved and shut
off. The water pump will automatically re-start when
it senses a drop in the water pressure. The pump is
designed for intermittent use only. Using the pump
continuously or with high pressure will shorten the
life of the pump and is not covered in your warranty.
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.
™ NOTE: The water pump switches should be in the OFF position when the
recreation vehicle is left unattended for any amount of time.
Maintenance
Periodically check the in-line water pump strainer for accumulated debris. To clean, shut
off the water pump, unscrew the clear cap, remove the re-useable metal strainer, clear any
debris, then reinstall.
Normal pump maintenance consists of checking and cleaning of the strainer, normal sanitiz-
ing and winterizing and occasionally checking all plumbing hardware and fittings for tight-
ness. 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 additional information on the care and operation of the pump, read the safety and operat-
ing information in the pump manufacturer's owner's manual.
Water Pump Switch
Most water pump switches illuminate when the water pump is activated. Typical switch
locations are in the back of the unit or on the monitor panel, or the switch may be art of a
touchscreen system (if so equipped). When the water pump switch is ON the pump runs until
45 lbs. of pressure has been achieved. The red light will stay on.
Fresh Water Connections
Your recreation vehicle may be equipped with one or both of the following fresh water con-
nections: city water and gravity fill. The city water fill
has a threaded connector with a city water connection
label next to it.
Do not remove this label.
Using City Water Fill
Remove the connection cap and attach a non-toxic
drinking water hose to the threaded inlet.
1.
The other end of this hose should be connected to a
pressurized fresh water source (such as a faucet or
spigot). You should use a non-toxic drinking water
hose dedicated only to supplying fresh water to the vehicle.
2.
Turn ON the water at the water source. Open the cold water supply faucets to bleed air
