Heres another water heater question. It may be dumb but better to ask a dumb question than to not ask and have a problem. I live in a mobile home and my water heater is in a closet. I just recently had to replace the flooring under the heater because of two leaks, in the piping, within one year. Yesterday I noticed that the new floor which is now treated ply(and not particle board) was a little damp around the edges of the heater. Is this normal or is it posible I have a small leak somewhere at te bottom of the heater. I had to put a new drain valve onto the heater when I replaced the flooring, I don't see any water around the drain valve yet is it possible that it might have a small leak.Thanks in advance.
