Is an electrical problem causing repeated hot water tank breakdowns?

(Note: I posted a question about this problem in the plumbing forum in February and I'm still looking for a solution.)



Since May 2012, I've been having a recurring hot water tank problem and the latest plumber who repaired it recommended that we have an electrician take a look at the problem. Several times the tank has had to be repaired due to scalding hot water coming out of the faucets. The plumber thinks that the tank's thermostats might be getting stuck in the "On" position and that it might be caused by a power surge or some other electrical issue. Further details are below.



We bought our townhouse in October 2003 and we are the original owners. The original tank lasted about 8 and a half years. It was replaced in May 2012 with a Rheem 50 gallon electric tank. Since then, we've had to have a plumber come over four more times in less than 3 years. The second time was in February 2013 and the plumber replaced the tank with another (identical) Rheem 50 gallon tank. The third and fourth times we had to call a plumber were in May 2014 and January 2015.



To sum up, in less than 3 years since a new tank was installed, we've had to replace the tank once and repair it three times. Two of the repair jobs involved replacing heating elements and thermostats. One of the repair jobs involved replacing only the heating elements. The problem surfaces when we start to get scalding hot water coming out of our faucets. In at least some but not all of the cases, we've had very, very minor leaks from the tank with, in the worst case, a puddle on the floor less than two inches in diameter.



Does anybody think that an electrical problem could be at the root of our troubles?
