IHELP! have been struggling with my 50 gal Bradford White electric hot water heater (approx. 8 yrs old) for a week now. Woke up the other day to find my garage floor soaked and hot water draining out the overflow tube. I emptied and flushed tank, refilled, only for the problem to repeat itself as soon as the water got hot...Note: it has seemed hotter than normal the night before in the sink.
Since then I replaced both thermostats but as soon as I get the electricity back on within 10 minutes the drain tube had a pretty good flow coming from it..not just dripping! And the water is not THAT hot at the point. Do I take it that my next step should be replacing the pressure relief valve? Or is it a blockage in something else? Currently I am cutting electricity on only a few minutes as needed while catching overflow in buckets/tubs. I am attempting to make these repairs without incurring huge bills as I have just had to have both my roof and a/c units replaced.
What should be my plan of action on finding the correct fix? Thanks.
