As long as you're on the subject of water tanks... I have a ? Our water tank is the original tank. It's aluminum, but had been painted. Of course the paint, after 20 years is chipping off in places. It comes off in chips. I've power washed it to get as much off as possible and we simply don't drink that water. Although at our age, who cares if it causes slight brain damage... who would know. Any suggestions short of replacing the tank. 80 gallons and a pain to get it out if it has to be removed.
