We recently had our main water line replaced. Since then our water heater starting leaking at the overflow pipe. We changed out the prv and the leak stopped but now the breaker keeps kicking out when we try to heat the water. Our tank is about 3 years old and the we have the temperature set about 120-125 degrees. Do you think we could have too much water pressure coming into the house or could it be a heating element? Any help would be appreciated. It's an electric hot water heater.
