SANITIZATION

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.

1. Determine the amount of common household bleach needed to sanitize the system based on the fresh tank size.  The requirement is for 2 ounces of bleach per 15 gallons of tank size. If you have a 60-gallon fresh water tank, divide 60 by 15 (which is 4) and multiply by 2 (to get 8).  A 60-gallon tank will require 8 ounces of bleach.
2. Mix the bleach with water in a container such as a gallon jug. If the tank is filled through a pressurized fitting, pour the bleach into the hose before attaching the hose to the city water fill.
3. Pour the bleach solution into the tank and fill the tank with potable water.
4. Open all faucets (Hot & Cold) allowing the water to run until the odor of chlorine is detected. Allow four (4) hours of contact time to disinfect completely. Doubling the solution concentration allows for a contact time of one (1) hour.
5. Drain the fresh water tank. Refill the tank and flush the system until the odor has decreased. The residual chlorine odor and taste is not harmful.
