SECTION 7
PLUMBING SYSTEMS
While any pump switch is in the “ON” posi-
tion, the pump will automatically supply water
pressure as it is needed. It is recommended that
the pump switch be turned off whenever you are
away from the vehicle or not using the water sys-
tem. A slow leak in a faucet could drain the water
system and discharge the coach battery.
NOTE: The water pump does not need to be
switched on while the coach is connected
to a city water hookup. See “External
Water Supply” on the following page.
Initial Water Line Priming
1. Make sure that all water drain valves are
closed, including water heater valve. (Refer
to Section 10.)
2. Turn water pump switch to “OFF” position.
3. Fill water tank.
4. Open all faucets, hot and cold.
5. Turn on pump switch.
6. Close each faucet as it begins to deliver a
steady stream of water (close cold water
first). Leave hot water faucets on until they
also deliver a steady stream of water. This
will ensure that the water heater is filled with
water.
7. Check to be sure pump stops soon after all
faucets have been closed.
8. Pump is now ready for automatic operation.
Pump will start when a faucet is opened and
stop when the faucet is closed.
INSTRUCTIONS FOR
DISINFECTION OF FRESH WATER
SYSTEMS ON RECREATION
VEHICLES
(As approved by the U.S. Public Health
Service)
To assure complete disinfection of your fresh
water system, it is recommended that the follow-
ing procedure be followed on a new system, one
that has not been used for a period of time, or
one that may have become contaminated. This
procedure is also recommended before long
periods of storage such as over winter.
1. Prepare a chlorine solution using 1 gallon of
water and 1/4 cup of household bleach
(sodium hypochlorite solution). With tank
empty, pour chlorine solution into the tank.
Use 1 gallon solution for each 15 gallons of
tank capacity. This procedure will result in a
residual chlorine concentration of 50 ppm in
the water system. If a 100 ppm concentration
is required as discussed in item 3, use 1/2
cup of household bleach with 1 gallon of
water to prepare the chlorine solution. One
gallon of the solution should be used for
each 15 gallons of tank capacity.
2. Complete filling of tank with fresh water.
Open each faucet and run the water until a
distinct odor of chlorine can be detected in
the water discharged. Do not forget the hot
water taps.
3. Allow the system to stand at least 4 hours
when disinfecting with 50 ppm residual
chlorine. If a shorter time period is desired,
then a 100 ppm chlorine concentration
should be permitted to stand in the system
for at least 1 hour.
4. Drain and flush with fresh water.
EXTERNAL WATER
SUPPLY (“City Water”)
To connect to an external source:
1. Turn the demand pump switch to off.
2. Attach a hose from the external water source
to the city water connection in the water cen-
ter compartment on the left side of your
vehicle.
Chlorine is poisonous - recap bottle
and clean utensils after use.
Never use automotive type antifreeze
in your potable water system as it is
poisonous.
