The Fresh Water Tank Sanitizer from Thetford is a 2-part system that is designed for cleaning and sanitizing fresh water tanks and plumbing on RVs, trailers, campers, boats, water coolers, coolers, ice machines, refrigerators, ice chests, or any hard, non-porous surfaces that are washable.
Step 1: Clean with the detergent.
Add 1 ounce of concentrated detergent solution to the fresh water tank for every 4 gallons of tank capacity after emptying the tank.
Fill the tank with water and run the diluted detergent through each faucet, shower, and water outlet for 1 minute or more.
Rinse the faucet lines and tank by running fresh water through them after emptying the tank.
Step 2: Sanitize the water.
Prepare a solution of 2 ounces of product per 8 gallons of water after shutting off the incoming water line.
Wet all surfaces by applying or circulating the solution, allowing it a minimum contact of 60 seconds.
Drain the solution and return to service by reopening the incoming water lines.
The treatment is effective even in hard water and will not leave soap scum or grit.
Not a drinking water additive.
