Ozone to clean fresh water tanks

I was wondering if anyone else use O3 to clean their fresh water tanks/lines. After numerous complaints from the DW about our water smelling like chlorine or bleach, I now use a venturi when filling my tank which injects ozone from a small ozone generator. No more smell, and the O3 removes more nasties than chlorine.
We seldom drink from our tank, but we do brush our teeth, clean dishes, and obviously use it for showering.

    You are lucky that your municipality has a good record. Mine does not. On average, about twice a year, we get a reverse 911 call to the residence that the town failed a certain test of the water supply.

    x2. Also - some people are particularly sensitive to chlorine/chloramine - if your wife is one of those consider using an inexpensive water filter (charcoal based) when re-filling the FW tank. Charcoal removes chlorine.

    Do mean sanitize the FW system? I hope not. Most articles I have read state to clean the tank at least every 3-4 weeks. More in hot weather if the water (or RV) has sat without use. I can tell immediately if mine has gone south of cheese. It usually starts with foul smelling water from the hot water tank.

    Once in 15 years? My rig is only 8 years old and I've done it twice already.
  • Ordinary distilled white vinegar also will work.
  • Pour 1/4 cup of hydrogenperoxide in your fresh water tank. Totally safe and it will KILL all traces of bleach instantly.
  • Don't kid yourself. I've experienced episodes with women who become offended at odors not detectable by anyone else (males). To the point where they can correctly identify the BRAND of detergent used to wash your clothes.

    AROMATHERAPY?

    Male or female-oriented? Gimme a break.

    Able to detect low life husbands who cheat? This is a no-brainer. Stores down here commonly offer 8 colors of same-brand mopping soap. Each with its own aroma.

    O3 needs to bubble through whatever liquid medium to kill bacteria. The secret to O3 is to expose contaminated liquid to air (interface) and bacteria on the surface of the liquid get a full dose of it.

    O3 is my favorite drinking water sterilizer. UV purification water plants offer minimal sterilization, O3 plants offer a one year guarantee as long as the bottle's seal remains intact.
