SECTION 7 –
PLUMBING
7-6
Coaches with Full-Coach Water
Filtration System (in Water Center)
1. Open a faucet to relieve any water line
pressure, then remove the filter canister from
the filter base.
2. Remove the filter cartridge from the canister.
Seal it in a clean plastic bag and set aside for
reinstallation after disinfection procedure.
3. Pour 1 1/2 cups of household chlorine bleach
(sodium hypochlorite solution) into the empty
filter canister and 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 as discussed in step 6, use 3 cups of
household bleach.)
4. Connect a hose from a city water source to the
City Water inlet and fill the fresh water tank
completely. 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.
5. 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.
6. 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 (double the
amount of bleach) should be allowed to stand
in the system for at least 1 hour.
7. Drain the fresh water tank.
8. Reinstall the filter cartridge into the filter
canister, then refill the tank with fresh water.
9. 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.
)
10. Done - Water system is now disinfected.
City Water Hose Disinfection
NOTE: This procedure can be used periodically
to sanitize the city water hose, and can
be used as an alternate method of adding
bleach solution to the fresh water tank if
desired.
1. Connect your city water hose to the fresh
water inlet of your coach.
2. Remove the full-coach filter cartridge from
the filter canister to avoid prematurely
‘plugging up’ the filter cartridge. Refit empty
canister to filter head for procedure.
3. Hold the ‘city end’ of the water hose upright
and use a funnel to pour 1 1/2 cups of
household chlorine bleach (sodium
hypochlorite solution) into the hose. Keep the
end of the hose held upright to avoid draining
the bleach solution.
4. Connect the hose to a city water hydrant and
turn on slowly, allowing the water to force the
bleach through the hose, then continue filling
the tank with water. (This will disinfect the
city water hose at the same time.)
5. 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 (double the
amount of bleach) should be allowed to stand
in the system for at least 1 hour.
6. Drain the chlorinated water from the fresh
water tank and refill with clean water.
Continuous Tank Disinfection
(Superchlorination)
Some RVers like to ensure continuous
sanitation of their fresh water tank by
‘superchlorination’– maintaining an effective
low level of chlorine in the tank at all times.
WARNING
Chlorine is poisonous. Recap bottle and
clean all utensils after use.
