SECTION 7 -
PLUMBING

4. Let the system 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
allowed to stand in the system for at least 1
hour).
5. Drain the water tank and refill with fresh
water.
6. Open each faucet again and run fresh water to
flush chlorinated water from the lines. Run the
water until there is no odor of chlorine
detected in the water discharged. Do not
forget the hot water faucets.
(
You may need to leave a hot water faucet
open for some time to flush the water heater
with clean water. You may also want to turn
the water heater off until this is done to avoid
wasting energy trying to heat “unused”
water
).
7. Water system is now disinfected.
Disinfecting with City Water Fill
When disinfecting through the city water fill,
an external cartridge-type water filter assembly
must be connected in-line between the city water
hose and the city water fill to add disinfecting
solution to the tank. These filters are commonly
available at most RV supply stores.
NOTE: If you do not have an in-line cartridge
filter, see City Water Hose/Tank
Disinfection following this procedure for
an alternate method of adding bleach
solution to your tank.
1. Remove the filter cartridge and pour 1/2 cup
of household chlorine bleach (sodium
hypochlorite solution) for each 30 gallons of
tank capacity into the empty filter canister,
then screw the canister back onto the filter
base.
This solution will result in a residual chlorine
concentration of approximately 50 ppm in the
water system.
(If a 100 ppm concentration is
desired, use 1 cup of household bleach for each
30 gallons of tank capacity).
The bleach will be drawn into the tank when the
city water is turned on and the Fresh Water valve
is turned to the Tank Fill position.
2. Fill the tank completely, then open each faucet
in the coach and run the water until a distinct
odor of chlorine can be detected in the water
discharged. Do not forget the hot water
faucets.
3. Let the system stand at least 4 hours when
disinfecting with 50 ppm residual chlorine.
(If
a shorter time period is desired, then 100 ppm
chlorine concentration should be allowed to
stand in the system for at least 1 hour).
4. Drain the fresh water tank.
5. Install the filter cartridge into the filter
canister, then refill the tank with fresh water.
6. Open each faucet again and run fresh water to
flush chlorinated water from the lines. Run the
water until there is no odor of chlorine
