Sanitizing RV fresh water tank

Did that much.

I've always heard 1/4 cup bleach for every 15 gallons, and to sanitize before the beginning of each season (so once a year).

concentration of solution too of course but, I'd assume youre talking Clorox from the store too.

So once a year at the start of the year. This is the 1st full year we will have owned our trailer and I wasn't sure if it's an every trip thing or what. Thanks

Ya that's how I do it for years.  I do like to fill tank so all surfaces are treated.  I am guilty of too much bleach it seems but after few rinses all we taste is slight odor of city water.    Besides its a good way to flush out winter antifreeze crap too!
