Water System (Self-Contained)
The fresh water system consists of a city water
hookup, fresh water tank gravity fill, fresh water tank
and drain valve, water pump, hot and cold water lines,
water heater, fresh water line low point drain valves,
and faucets� Full explanations on the locations and use
of these features are explained in this section�
Before using a water system, check that the water
heater bypass valve is turned to the use position� See
Winterizing and Storage for further information on the
bypass� Check that the water heaters drain valve is
closed� Close all low point drain valves and the fresh
water tank drain valve�
Fill the water tank by opening the exterior gravity
feed water fill door. A high-pressure RV/Marine FDA
approved drinking water hose of at least ½-in� diameter
made from material that is tasteless, odorless, and
non-toxic can now be inserted, or use a clean bucket
and funnel to fill the tank. It’s a good idea to let the
water run through a hose for a short time to flush it out.
RVers sometimes fill their tanks with “home” water to
avoid strange water that may be distasteful to them on
short outings� Remember, the more water you carry in
the Fresh Water tank, the less cargo carrying capacity
you have for other items� The amount of water in the
tank may be checked on the Multiplex Control Panel�
Because the water heater is tankless it does not need
to be filled. However, if the system has not been used
for some time or is being used for the first time since
draining the lines it is normal for air to have gotten into
the lines� To expel the air, open the hot side of either
the galley, wet-bath, or exterior shower faucet and turn
on the water pump or connect to an exterior city water
source� Close the cold side of all faucets� For some
time the open faucet will only sputter� This is because
the air is being pushed out through the lines� Once the
air is expelled, a steady stream of water will come from
the faucet�
Now, open a cold faucet� It will sputter for a short time,
but will soon expel a steady stream� All other faucets
can now be opened until all air is expelled�
Once the system is filled with water and the faucets are
closed, the water pump will shut off� When a faucet is
opened, the pump will come back on automatically� If
the faucet is just barely open, it is normal for the pump
to cycle on and off rapidly�
It is normal for a pump to occasionally cycle when all
faucets are off to keep the water pressure at the set
point� However, if it cycles frequently (e�g� more than
a few times an hour) the plumbing system, pump, and
pump strainer should be checked to be sure it is not
losing pressure through a slow water leak or back
through the pump�
NOTE
To prevent equipment damage, the water heater
should only be started after the water system is
primed and ready for use.
NOTE
Turn the water pump off when the touring coach is
left unattended or in motion.
Water Pump and Strainer
The water pump is controlled by the Multiplex Systems
control panels� Once the switch is turned on, the pump
will run until the water pressure reaches approximately
50 psi� At this point, an internal pressure switch will
shut it off� When a faucet is opened, the water pressure
will drop and the pump will start to run again�
As a general rule, the water pump should be turned off
while using a city water hookup; however, the water
pressure at some campgrounds may be low� The water
pump can be turned on to assist the city water hookup
pressure� Be sure there is some water in the fresh
water tank� The pump will only use the water that is
needed out of the tank to bring the pressure up to the
usual standard of 50 psi�
The water pump and strainer are located under the
galley accessed by removing the galley drawer, or
below the refrigerator and accessed by removing the
panel, depending on the model� The strainer should
be visually checked for accumulation of sand or debris
that could affect water flow.
To clean the strainer screen: with the clear plastic at
the top, press on the sides of the strainer releasing
the tabs holding the clear plastic top in place, hold the
