WARNING
Before setting the water pump to the “On” mode, make
certain all faucet and shower fixtures are turned off. Pay
particular attention to the outside shower located in the wet
bay compartment, as it may be inadvertently turned on when
an operator has installed the water supply hose or has been
operating the macerator dump valves and hose. When this
happens, water may appear to be suddenly pouring out from
beneath the vehicle.
The water pressure pump has an inlet on one side that connects
directly to the coach’s onboard freshwater storage tank� At the
entrance to the inlet is a round particulate filter screen in a clear plastic
bowl-shaped housing� The screen may be removed for cleaning by
unscrewing the plastic filter housing from the pump.
Always turn off the pump and shut off the city water supply before
servicing the inline water filter. Place an absorbent towel beneath the
filter before removing it as a small quantity of water will dribble out of
the housing once the filter and cup assembly are removed. Failure to
turn off the pump and the water supply could result in water suddenly
entering the coach�
See the pump’s side view below.
warning
See the pump’s top view below.
The water pump is easily accessible for repair and / or winterization�
It is fastened to the coach with four screws via isolation mounts with
rubber grommets to reduce vibration� When the pump runs it will
generate a low frequency vibration inside the coach� This is normal�
If the pump runs continuously, check the water tank level as the tank
may have run dry� Otherwise, a continuously running pump indicates
a fixture is open allowing water to be pumped through the system.
Directly adjacent to the pump is a winterization valve and fitting
arrangement, which permits the introduction of non-toxic RV antifreeze
into the water system� One valve shuts off the incoming water supply�
The other valve allows anti-freeze to flow into the system after a
supply source of anti-freeze has been connected through the
antifreeze fill connection fitting. This process is covered in greater
detail later in SECTION 12 – WINTERIZATION AND STORAGE�
