The main "got-ya" is continually using shore water, allowing the water in the on-board tank to sit and sit and sit...... If that happens, then, yes the tank needs to be drained and the whole system sanitized. Ditto Brett! Share this post Link to post Share on other sites

With an empty tank fill with 1 pt and about 15 gallons of water. Run the pump and turn on each faucet hot and cold including the kitchen sink rinser. Fill the tank to the desired capacity and just begin using the system. Some time ago I had a discussion with an engineer in charge of the water quality at a chemical plant and he said they use hydrogen peroxide on a regular basis. I had something growing in my kitchen sink rinser line and full strength bleach wouldn't kill it. Used hydrogen peroxide and the problem was cured. What strength hydrogen peroxide do you use? Off the shelf at Walmart or a more industrial strength. Share this post Link to post Share on other sites
