WATER SYSTEM - SELF-CONTAINED
Most exterior plumbing functions are accomplished in the plumbing utility compart-
ment on the roadside of your motorhome. To fill your water tank, hook up a garden
hose to the city water inlet then open the water tank fill valve in the upper right corner
of the compartment. The water level can be monitored on your control panel above the
range or the tank can be filled until water is expelled out gravity fill vent tube.
If it is more convenient for you, a water fill is also located on the side of the vehicle.
Open the small access door, unscrew the cap, pull the air plug, insert water hose
and fill.
Open the hot side and cold side of the galley faucet and turn on the water pump switch
located on the monitor panel. For some time the open faucet may only sputter. This is
because the water lines are being filled and air is being pushed out through the lines.
Once the line are filled and a steady stream of water is coming from the faucet, shut off
the faucet and start the Hydro-Hot Water sytem.
All other faucets can now be opened until all air is expelled.
Once the system is filled with water and the faucets 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.
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. The water pump should be turned off when the
motorhome is left unattended.
Cleaning Water Storage Tank
1. Prepare sodium hypochlorite solution using potable water and household bleach (5
1/4 to 6%) in the ratio of 1/4-cup bleach to 1 gallon of water. (Common household
bleaches are Purex and Chlorox.)
2. Pour 1 gallon of hypochlorite solution for each 15 gallons of capacity into the empty
water tank.
3. Add enough potable water to completely fill the water system.
4. Allow closed system to stand for three hours.
5. Drain the hypochlorite solution from the system and refill with potable water.
6. Excessive hypochlorite taste or odor remaining in the water system is removed by
rinsing the system with a vinegar solution mixed in the ratio of 1 quart of vinegar to
5 gallons of water.
7. Drain the system and flush with potable water.
