Excessive pressure from water supply
systems may be encountered in some parks,
especially in mountain regions. Water
pressure regulators are available to protect
the RV water system against such high
pressure. Water pressure regulators
(customer supplied) are available from your
RV dealer to protect the RV plumbing system
against such high pressure.

Once activated, the
water pump (also
known as the
demand pump) will
self-prime, and
provide water. The
water pump
continues to run until
approximately 45 lbs.
of pressure is
achieved then 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.
The water pump switch should be in the
OFF position when the RV is unattended
for any amount of time. If something would
happen to the water system, this may help
limit water damage to a smaller area.
Dry camping
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.
Fig. 8.4 Water pump strainer
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.

The water heater is designed to heat water
quickly and efficiently. The water heater OEM
has preset the sensing limit to maintain the
water temperature when the water heater is
activated. If you have not used the water
heater for two weeks or more it may result in
hydrogen gas in the water lines. 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 probably will hear
an unusual sound such as air escaping
through the pipe as the water begins to flow.
Hydrogen gas may be present even after
water has been drained from the tank. Open
faucet at the sink and allow the water system
to vent for five to ten minutes (or as needed).
Not using a water pressure regulator when
using city water may cause the o-rings to
blow. To prevent damage to the plumbing
system or components when using the city
water connection, a 45 lb. (315 Kpa) rated
water pressure regulator is recommended.
Fig 8.3 Water pump
Do not replace any component part with an
accessory part that is not authorized by the
water heater OEM (i.e., an “add-on”
electric heating element, etc.). Such items
are not approved to be installed and could
create an unsafe condition and will void all
warranties.
