General Information
It is hard to imagine how much
water you use everyday when you are at
home. Newcomers to self contained
motor homes soon discover that water
does not last very long unless consump-
tion is drastically reduced. For
instance, you can use less water for
showering if you wet down; turn off
water while soaping; then turn on water
to rinse. This way a good shower uses a
gallon or less of water. There is plenty
of water to meet your needs once you adjust your habits.
There are two different water systems in your motor home. The fresh water sys-
tem consists of the fresh water tank, water pump, water heater and a city water connec-
tion. The waste water system consists of a waste holding tank (gray water), a sewage
holding tank (black water), toilet and
drains.
The control panel for these two sys-
tems has a water pump switch, water
heater switch and level indicator lights for
tanks. To check water level of all tanks
push test button on left side of panel.
Water Pump
A water pump is used to pressurize the fresh water system when it is not connected
to city water. The water pump is totally automatic and self-priming, operating on
demand as water is used. The pump is located in an outside water connection panel
compartment on the road side of motor home. To operate pump, check water level in
tank from the control panel; refill if necessary (see “Fresh Water Tank Fill”). Open all
valves and faucets except drain valves. This includes hot and cold water valves, all
faucets, and shower. Make sure water heater bypass valve is set to NORMAL FLOW posi-
tion (see “Water Heater Bypass System”) so that water can run into your water heater.
Turn pump on by pushing switch on control panel and wait for water lines and hot water
tank to fill. Close each faucet when it delivers a steady stream of water (cold water faucets
first). The pump is now ready for automatic operation. It will start when a faucet is
opened and stop once faucet is closed. Do not allow pump to run when the fresh water
supply tank is empty. Continued operation with a dry tank may open an electrical cir-
