SECTION 8 - PLUMBING SYSTEMS
12-V W
OLT ATER
Once activated, the water pump (also known as the on-demand pump) will self-
prime, and provide water. The water pump continues to run until approximately 45
lbs. of pressure is achieved and shut off.
The water pump will automatically re-start when pressure drops. Some cycling
may occur, depending on the volume of water being released. The water pump
has a built-in check valve to prevent water from back flowing.
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 and clear any debris, then reinstall.
Water pump switch (if so equipped)
When the water pump switch is ON the water pump runs until 45 pounds of
pressure has been achieved. The red light will stay ON. Turn the water pump
switch OFF when it is not in use.
The water pump switch should be in the OFF position when the RV is left
unattended for any amount of time. If something would happen to the water
system, this may help limit water damage to a smaller area.
NOTE: When you want to use water in your RV and the RV is not hooked up to
city water, you will need sufficient 12-volt DC power to run the water pump.

ATER EATER
The water heater is designed to heat water quickly and efficiently. The water
heater manufacturer has preset the sensing limit to maintain the water
temperature when the water heater is activated.
Hydrogen gas may result if you have not used the water heater for two weeks
or more. HYDROGEN GAS IS EXTREMELY FLAMMABLE. To reduce the
risk of injury under these conditions, open the hot water faucet for several
minutes at the kitchen sink before you use any electrical appliance connected
to the hot water system. If hydrogen is present, you may hear what sounds
like air escaping through the pipe as the water begins to flow. Hydrogen gas
may be present even after water has been drained from the water heater
tank. Open the faucet at the sink and allow the system to vent for five to ten
minutes. Do not smoke or have any open flame near the open faucet while
venting. On DSI water heater models, make sure the switch is OFF.
