PLUMBING
tank empty, pour chlorine solution into the
tank through the gravity fill port.
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.
NOTE: If a 100 ppm concentration is desired,
use 1/2 cup of household bleach with 1
gallon of water to prepare the chlorine
solution. One gallon of this solution
should be used for each 15 gallons of
tank capacity.
WARNING
Chlorine is poisonous. Do not misuse.
Recap bottle and clean all utensils after
use.
2. Complete filling of tank with fresh water.
3. Open each faucet in the motorhome and run
the water until a distinct odor of chlorine can
be detected in the water discharged. Do not
forget the hot water faucets.
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 1/4 cup
of household chlorine bleach (sodium
hypochlorite solution) for each 15 gallons of
tank capacity into the empty filter canister,
then screw the canister back onto the filter
base.
WARNING
Chlorine is poisonous. Do not misuse.
Recap bottle and clean all utensils after
use.
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 1/2 cup of household bleach for each
15 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 Tank Fill position.
