Sanitizing RV Water System

You should sanitize your RV water system every spring after de-winterization, or anytime you detect an odor from the water. The process is simple. You need some household bleach, fresh water, and some patience. (you have to let the bleach work for 12 hours).

• The first step is to drain all water from the system holding tanks and hot water heater, once that is complete, close all the drains again.
• Take 1/4 cup of household bleach for every 15 gallons of water your fresh water tank holds, and mix the bleach with water in a gallon container and pour it into the fresh water tank. Then fill the fresh water tank completely full of water.
• Turn the water pump on, and open all hot and cold water faucets on one at a time until you smell bleach coming out at each faucet.
• Then close the faucets and let it sit for at least 12 hours.
• Drain the system and re-fill the fresh water tank with fresh water.
• Open all the faucets and run the water until you no longer smell any bleach. It may be necessary to repeat this step to remove all signs of bleach from the water system.
