INSTRUCTIONS FOR DISINFECIION OF POTABLE WATER SYSTEMS ON RECREATION
VEHICLES

As approved by the U.S. Public Health Service

To assure complete disinfection of your potable water system, it is
recommended that the following procedures be followed on a new system, one
that has not been used for a period of time, or one that may have become
contaminated. This procedure is also recommended before long periods of
storage such as over winter.

1. Prepare a chlorine solution using 1 gallon of water and 1/4 cup of
household 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
required as discussed in item 3, use 1/2 cup of household bleach with 1
gallon of water to prepare the chlorine solution. One gallon of the solution
should be used for each 15 gallons of tank capacity.

2. Complete filling of tank with potable water. Open each faucet and run the
water until a distinct odor of chlorine can be detected in the water
discharged. Do not forget the hot water taps.

3. Allow the system to stand for 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 permitted to stand in the system for at
least 1 hour.

4. Drain and flush with potable water.
