There must be sucient 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 pump is designed for
Using the pump continuously or with high pressure will shorten the life of the
pump and is not covered in your warranty.
Periodically check the in-line water pump strainer for accumulated debris. To clean, shut
o the water pump, unscrew the clear cap, remove the re-useable metal strainer, clear any
debris, then reinstall.
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.
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. When the water pump switch
is ON the pump runs until 45 lbs. of pressure has been achieved. The red light will stay on.
The water pump automatically recycles when pressure drops. Some cycling may occur de-
pending on the volume of water being released. Turn the water pump switch OFF when it is
not in use.
In some models the water
pump switch will be a black rocker
switch located near the sink cabinet
Draining The Fresh Water System
Water tanks may be drained through a valve located near the tank. A
recreational vehicle with a demand pressure pump system will have
low-point drains attached to the water lines (normally located near the
water tank).
These low-point drains will release water in the supply lines by opening
the valves and all faucets. The water heater has its own drain plug. To
drain the permanent fresh water holding tank and supply lines:
1. Turn the water heater power OFF (turn o the electric and LP gas
switches).
2. Open all faucets, including the outside shower faucet (if so
equipped).
3. Open the “fresh tank drain” valve. All fresh water tanks can be
drained by one of two types of drain valves. A white plastic drain
is attached to the exterior wall or a valve located inside the RV ad-
jacent to the water tank (turn 45° to open or close).
