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,
hydronic heating and hot water system, faucets, and an
external sprayer port� Full explanations on the locations
and use of these features are explained in this section�
Also, see Water Service Compartment on page 6-6�
Before using the water system, ensure the low point
drain valve is closed; see Component Locations for
Winterization on page 9-10 �
Fill the water tank by opening the right rear door to
access the gravity water fill. For instructions on using
the gravity water fill, see Gravity Water Fill on page
6-6 �
NOTE
To prevent equipment damage, the hydronic water
heater should only be started after the water
system is primed and ready for use.
Water Pump and Strainer
The water pump and strainer are behind the large
panel on the face of the curbside bed base� Turn the
water pump on by pressing the Water Pump icon on
the Multiplex home screen� Once 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� The water pressure will drop when opening
the faucets, and the pump will start to run again�
As a general rule, the water pump should be off when
connected to a city water source; however, the water
pressure at some campgrounds may be low� To assist
the city water hookup pressure, turn on the pump� To
use the water pump while hooked to city water, you will
need some water in the fresh water tank for the pump
to function properly� The tank does not need to be full
as the pump will only use what it needs to increase the
pressure to 50 psi�
Cleaning the Strainer
The strainer is mounted at the water pump inlet�
Visually inspect it for accumulation of dirt/debris that
could affect water flow and clean as needed:
1� Rotate the strainer housing to a position allowing
access to the clear-view screen retainer and the
tabs holding it in place�
2� Pinch the tabs inward to release the clear plastic
retainer (as shown above)�
3� Pull the retainer and screen out of the housing for
cleaning� Rinse all debris from the screen�
4� Replace the screen assembly by aligning the
screen in the seating groves and pressing down
gently until the tabs are back in place�
Disconnecting the Strainer/Water Pump Lines
The inlet and outlet hoses and the strainer assembly
are held in place by self-sealing, blue, quick-connect
fittings:
1� Grasp the blue tab on the female fitting by the
grooved finger edges and pull straight out on the
tab to release the male fitting.
2� Be sure that both the female and male fittings on
the disconnect are free of all debris and damage
before replacing them�
3� Check the pump system for leaks when reinstalling
the disconnect fittings.
