How to sanitize your fresh water system

If your coach has been in storage, or you just haven’t sanitized your fresh water system in a while, here is an easy way to do it.

First, drain the fresh water tank by opening the tank drain valve. Next, add ¼ cup of household bleach for every 15 gallons of water your tank holds. That is approximately 1½ cups of bleach for a 100 gallon tank. The easiest way to get the bleach into the tank is to simply pour it into your fresh water hose, then hook it to a spicket and fill the tank.

Using your water pump, turn on each faucet (hot and cold) until you smell bleach. Close the faucets and let everything set for at least 12 hours.

Next drain the entire system again and refill with fresh water. Using the water pump, open all hot and cold faucets and run until you no longer smell any bleach. Once this is done, your fresh water system is now sanitized, and you are safe to use it again.
