Thanks very much for your reply. We keep the fresh water tank drained when we are sitting in one spot and using shore water all the time. We sanitize the tank prior to moving again, because we figure there was probably a bit of water that did not drain. Hate to put the bleach solution though the whole water system if not really necessary, trying to figure that out?
We are full time. Prior to starting out 3 years ago the fresh water tank and faucets were sanitized with bleach. Periodically we have sanitized the fresh water tank with bleach, but not run the bleach solution through the faucets. The idea being that we are continuously running water through all the faucets, so there is no opportunity for mold, mildew or bacteria to reside. Should we be running the bleach solution through the faucets anyway?
