Cleaning fresh water tank with bleach

If you smell bleach, add a tablespoon of baking soda in some diluted water. Add it to the system and flush well.

Odds are if mold was in the tank it is in all the lines and the hot water heater. Drain the hot water heater. Put a mixture of bleach and water in the tank and use it to fill the hotwater heater. Then run the mix through every outlet. Let it sit for a day then run more through. If you do not drink the water you could put a cup or so of NONSCENTED bleach in the tank every time you fill it. It will be dilutued enough that it will not hurt anything but strong enough to keep the mold at bay.

I agree with the above, do it twice.

Usually a couple of times will do it. But if you had actual mold growing, I'd rinse it twice then add more bleach and repeat the sanitizing process leaving the diluted bleach sit at least 12 hours in the tank and water lines then flush again with clean freshwater..

Till you no longer smell bleach at the faucets should do it.
