How do you sanitize your fresh-water tank and lines?

My eyes aren't as good as yours. I can't see bacteria.

BTW, cith water has chlorine in it and apparently this is enough to do the job…

All campgrounds don't have chlorinated water supplies.

OP, I think most folks, including myself, sanitize our RV water tanks periodically. Once or twice a year for me.

I use either bleach or Purogene. Bleach is cheap, but caustic as hell. Purogene is pricey but easy on people.

For a typical 50ppm bleach sanitize, it's 1/4 cup bleach per 15 gal of holding tank capacity and let sit for 4 hours. For a stronger (100 ppm) concentration, it's 1/2 cup bleach per 15 gal and let it sit 1 hour.

Finally, you'll probably get some interesting rationale from folks who never sanitize their water tanks like . . .

- "I haven't gotten sick yet." (Also a popular excuse for smokers.)

- "I used to drink out of a water hose when I was a kid" (What this has to do with tank sanitation still escapes me.)

Okay Fair enough (though from my perspective, a bit of myopic hyperbole :R…), but we fill the tank before each outing with pre-chlorinated city water, and we drink only bottled R.O. (reverse osmosis) processed water, and if you care to think about it (whether at home or not…) chlorine is a very effective and economical water disinfectant which has benefited the entire world (especially, due to economics, the third world), but chlorine is also a known well established carcinogen (though this fact is mostly dismissed - possibly a mere case of ignorance is bliss??…), whereby the bulk of one’s exposure occurs through directly the derma (skin) when bathing… So in my view, rather than paint with such a broad brush (facts matter, eh?), in my judgement each person need be aware of this risk and (based on information) chose whatever the best informed option of their own choice - FWIW, this may contrary to conventional wholesale wisdom…

I would also add here that the chlorine in city water tends to evaporate from a storage tank in about 30 or so minutes, we see the same thing happening in swimming pools as well…

Well, this migh surprise some but there’s about 2 billion bacteria within the human body’s interstitial fluids alone, all of which are in circulation and are beneficial (by design, ingesting toxins)… Point being (ego aside - lol) is that we are all just another part of this vast biosphere…

Thanks in advance ‘for tolerating’ this opposing point of view…
