DISINFECTING YOUR FRESH
WATER SYSTEM
(As required by NFPA
Recreational Vehicles)
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. 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. 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.
If a 100 ppm concentration is desired as
discussed in Step 4, 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 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.
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
