Disinfecting Your Fresh Water System - Winnebago 2015 Tour Operator's Manual

SECTION 7 –
PLUMBING
• Turn the Fresh Water Valve to Normal
position. Next open a faucet inside the coach
or the exterior shower, then turn city water on
SLOWLY to allow the canister to fill with
water.
• Thoroughly flush the filtration system by
running the water for twenty (20) minutes.
• Check for leaks.
See "Winterizing Procedure" in this section to
prepare the water filtration system for freezing
conditions.
DISINFECTING YOUR FRESH
WATER SYSTEM
(As required by NFPA
Recreational Vehicles)
–For coaches with Full-Coach Water
Filtration System
To ensure complete disinfection of the potable
water system, it is recommended that the
following procedure be followed on a new
system, one that has not been used for a period of
time, or one that could have become
contaminated.
This procedure is also recommended before
long periods of storage such as over winter.
Disinfecting with Gravity Fill
1. Open a faucet to relieve any waterline
pressure.
WARNING
Chlorine is poisonous. Do not misuse.
Recap bottle and clean all utensils after
use.
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.
