end into the gravity fill. Turn on the clean
(potable) water and when the fresh water tank
is full, shut OFF the water pump and remove
the non-toxic drinking water hose.
WATER PRESSURE REGULATOR
(CUSTOMER SUPPLIED)
Excessive pressure from water supply
systems may be encountered in some parks,
especially in mountain regions. Water
pressure regulators are available to protect
your system against such high pressure. A
regulator of this type is recommended to
prevent damage to the plumbing system or
components. Water pressure regulators
(customer supplied) are available from your
Dealer to protect the RV plumbing system
against such high pressure.
12-VOLT WATER PUMP & SWITCH
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 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 is engineered by the OEM with a check
valve to prevent water from back flowing into
the fresh water supply tank
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. Depending on your trailer model,
the pump will be located under the bed, in a
cupboard, under the unit or under the sink.
The switch to operate the water pump is
located on the monitor panel or an interior
wall.
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.
Fig. 8.3 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.
WATER HEATER
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 in the
water lines may result if you have not used
the water heater for two weeks or more. 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
Not using a water pressure regulator when
using city water may cause the o-rings to
fail. To prevent damage to the plumbing
system or components when using the city
water connection, a water pressure
regulator rated for 40 lbs. is
recommended.
Do not replace any component part with an
accessory part that is not authorized by the
water heater manufacturer, such as an
“add-on” electric heating element. Such
items are not approved to be installed and
could create an unsafe condition and will
void all warranties.
