We moved into a new-used home about a year ago. 6 months ago our water no
longer got very hot. We had a plumber come out and install a new element in
our heater. (I believe there are 2 and he replaced 1). 2 days ago our hot
water got VERY hot. It will cause a burn if you hold hand under it now. Is
this indicative of a failing element? The hot water heater is probably 20
years old...probably time for new one? Or should we check on replacing the
other element?
