WATER SYSTEMS - 6
CAYMAN 2007 117
The water pump can be
either off or on. It will not
affect the water pump to
leave it ON.
The City Water Hook-up
in the service center has a
built in pressure regulator
and one-way check valve.
The pressure regulator
limits the water pressure to
approximately 45 psi.
CAUTION:
Some outside water sources develop
high water pressure, particularly in
mountainous regions. High water
pressure is anything over 55 psi (pounds
per square inch). Excess pressure on
a hot day can cause the water hose to
swell and burst. Excess pressure on
a hot day can cause the water hose to
swell and burst. An additional pressure
regulator can be connected to the city
water faucet to regulate the pressure to
the potable water hose.
WATER PUMP
The water pump pressurizes the fresh water
system when not connected to city water.
The water pump is self-priming, operating on
demand as water is used. The water pump is
located behind the water service panel. Access
the water pump by removing an access panel in
the pass-through storage bay next to the water
service center.

that are loose. Many symptoms can be resolved
by tightening the hardware. Check the following
items:

fuse:
Check the electrical connections, fuse
or breaker, main switch and ground
connection.
Is voltage present at the pressure switch
on the pump? If voltage is present, the
pressure switch may be faulty. As a test,
temporarily bypass the pressure switch.
Check the charging system for correct
voltage and good ground.
