1. Pump the water tank empty. Shut OFF the Fresh Water Pump breaker.
2. Determine the capacity of your water tank (your standard water tank holds 24 gallons (90.8liters). You will need approximately one (1) gallon of weak bleach solution for each fifteen (15) gallons of tank capacity.
3. Prepare the proper amount of a weak bleach solution by mixing 1/4 cup of unscented household chlorine bleach per gallon of water.
4. Pour weak bleach solution into the water tank. Remember, use about one (1) gallon of weak bleach solution for each fifteen (15) gallons of tank capacity.
5. Fill the remainder of the tank with fresh, clean water. This will further dilute the weak bleach solution.
6. Switch ON the Fresh Water Pump breaker, then turn on the faucets and allow the air to be exhausted from the plumbing system. By doing this, the entire fresh water system will be filled with a sanitizing solution.
7. Allow the sanitizing solution to stand in the water system for three (3) hours.
8. Pump the water tank empty.
9. Fill the water system completely with fresh, clean water. Turn on the faucet and permit the entire contents of fresh, clean water to run through the system. This will flush the sanitizing solution out of the plumbing.
10. Fill the water system again, with fresh, clean water, and turn on the faucet to permit the air to dissipate.
Your water system is now sanitized.
