        I have two 40 gallon hot water heaters that are 10 years old. I have noticed some calcium deposits and rust where the copper pipes attach to the fittings on top of the heaters. Should I call a plumber?

          If you have copper pipe connected to steel pipe, you need to have a dielectric union
          to prevent galvanic corrosion. If you don’t have a dielectric union, the steel pipe will corrode at a fairly significant rate, until it fails. It will always fail at 2 am on a weekend night, when you are out of town!

            Thanks for the information. A plumber will be out tomorrow to check out the problem.
