Update: This post was written before I started living in our RV. I now sanitize the fresh water tank about every 3 months. I’ll update the process soon.
There are a lot of great tips to be found on the web. I was reading the top 10 RV tips. I’m one of those RVer’s who doesn’t use the tank for , in fact the majority of the time that tank is empty. So I never gave much thought to sanitizing the fresh water system. I know..Gross…Don’t tell my wife. The site recommends every 6 months sanitizing the entire system. Is this a good for an RV that sits over the winter with the drain valves open. Is an annual cleaning good enough or should it be more often. What do you do?
