Our tank has developed a pin hole and has a slow leak. Can I use epoxy or something to stop the leak ?

Thanks, Ted O.

Well, it won't hurt to try it. I'd make sure it was clean and dry. However, if it is leaking, it is likely rusting from the inside out, and if that's true, then replacement is a good option. How old is your tank?

Is supposed to be plastic lined to prevent corrosion.
