Chapter 6 - Plumbing Systems
Your motorhome is self contained, able to carry fresh water in the potable storage tank
and hold the wastewater in dual holding tanks for dumping when convenient. Water
connections are also available for a city water hose hookup to an external pressurized
water source.
The fresh water storage tank supplies potable water to all fixtures within your motorhome
by means of a 12 Volt water pump. This pump is located close to the storage tank
and is equipped with a check valve that ensures directional flow away from the tank.
The pump has an on/off switch, which is located on the monitor panel, bathroom, or
termination compartment. The pump will automatically build up pressure and maintain
that pressure when turned on. The pump should be turned off when the fresh water tank
is empty or when the motorhome will not be in use. Continued operation with a dry tank
may damage the pump. Your pump has a filter on the inlet side. This filter should be
cleaned after each tankful of water for the first few uses. To remove the cover press in
firmly and twist counterclockwise about one eighth turn. Pull the screen out of the bowl
and rinse clean. Reassemble in the reverse fashion. For more information check your
water pump Owner’s Manual located in your Owner’s Information Kit.
The fresh water tank can be filled by an external hose through the potable water fill
located outside your unit. To fill, make sure that the tank and low point drains are closed.
Simply connect the external hose directly to the receptacle labeled “Potable Water” on
the outside of your motorhome. Turn on the external water source and the tank will fill
up. Check the monitor panel while filling the tank to determine how full the tank is. When
full, water may spill back out through the inlet or vent. There is no automatic shut-off for
the fresh water tank fill. When completely filling the tank to maximum water capacity, fill
all water lines and the water heater as well. When possible, traveling with an empty fresh
water tank will provide for more cargo carrying capacity and better gas mileage.
If you choose to use city water directly for your water source, simply attach the external
hose to the inlet labeled “City Water” located on an exterior side of your motorhome.
Now you have a pressurized water supply from the motorhome park or city water supply
hookup. The same water lines are utilized as with the fresh water storage tank and
pump; however, the pump’s check valve bypasses both the pump and the fresh water
tank. Turn on the water supply and open faucets to purge any air trapped in the water
system.
Some water sources develop high water pressure, particularly in
mountainous regions. These campgrounds or hookup locations may not have
regulated water pressure, which could be considered excessive. High pressure is anything over 55 psi.
Excessive pressure may cause leaks or damage to your water system. Water pressure regulators are
available to protect the water system against high pressures. Check with your dealer for recommendations
of water pressure regulators.
