Leaking Water Expansion Tank
I have a Watts Water Expansion Tank, I assume it is the 2 gallon size, that has developed a leak in the tank. It is attached to my hot water heater and when the cold water valve is turn on, a fine thin spray of water comes out of the top of the unit. It is not leaking where it is attached to copper pipes. It is about 6 years old, we build our house in 2001 and it was originally placed by the builder. I assume I will need to replace the tank. I have basically 2 questions. Any idea on how this leak could have come about? The unit is an all metal constructions. The second question, can this repair be done by someone with absolutely no plumbing experience or would it be safer to use a plumber?
