When cleaning our tanks, which we do about two (2) times per year (yr round boating in PNW) we:
- Add 1 tbl spoon unscented bleach : to 1 gallon tank capacity - Leave in tanks 3 - 24hrs (best if this is done while sailing) - Remove aerators/ screens from sinks and drain tanks of bleach mixture - Fresh fill all the way, then drain this as well - Fill up as normal (we can smell a very slight bleach smell on this tank, but very very slight) We drink and cook from our tanks no problem. We also use a screw on type RV filter, before we bring any water aboard. We do this somewhat often so you may need to repeat the procedure a few times before it's taken care of. I agree with previous comment, don't kill the fittings with strong bleach.
