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?
