PLUMBING SYSTEMS
10 - PLUMBING SYSTEMS
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.
Models not equipped with Gravity
Water Fill
Follow the preceding instructions for
disinfecting tanks with gravity fill, with the
exception of tank filling described in Step 1.
Models without a gravity water tank fill
require temporarily connecting an external
cartridge type water filter assembly to add
disinfecting solution to the tank. These filters are
commonly available at RV supply stores.
Bleach can be placed into the empty filter
canister (remove the filter cartridge first) and
connected in-line with the city water fill and city
water hose.
The bleach will be drawn into the tank when
the city water is turned on and the tank fill valve
is turned to Tank Fill position.
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 utility
compartment or on the left side of your
vehicle.
3. Turn water tank fill valve to CITY FILL
position.
NOTE: Because city water pressure varies from
location to location, we recommend
using an in-line water pressure regulator
to prevent damage to any components,
connections and seals in your fresh
water system.
Chlorine is poisonous - recap bottle
and clean utensils after use.
