SECTION 7 –
PLUMBING
7-8
NOTE: 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 3 cups
of household bleach).
2. Prepare a chlorine solution using 1 gallon of
water and 1/4 cup of household chlorine
bleach (sodium hypochlorite solution). With
tank empty, pour chlorine solution into the
tank through the gravity fill port (located in
the first passenger side compartment).
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.
3. Complete filling of tank with fresh water.
4. 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.
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 should be
allowed to stand in the system for at least 1
hour.
6. Drain the fresh water tank.
7. Refill the tank with fresh water.
8. 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.
9. Water system is now disinfected.
City Water Tank and Hose
Disinfection
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 a water hose to the Fresh Water Inlet
(located in the water service center).
2. Turn the Fresh Water valve to the Tank Fill
position.
3. Remove the Full-Coach Water Filtration
cartridge from the filter canister. Refit empty
canister to filter head for procedure.
4. 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.
5. Connect the hose to a city water source 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).
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 should be
allowed to stand in the system for at least 1
hour.
7. 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.
•
Add 1 teaspoon of chlorine bleach (sodium
hypochlorite) to your tank for each 10 gallons
of tank capacity. When you fill the tank, this
will result in a 6.7 ppm level of chlorine,
which should kill harmful bacteria and slime-
forming organisms.
