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.

Sounds like a bad pressure relief valve. I'd replace it and then see if
problem wasn't solved.

I find that "hotter than normal" worrisome, whatever ever else you
do, do NOT plug the valve or cap the pipe attached to it, even as a
temporary measure...

and THAT was only a 5 gal unit.

broke,

I'm betting that your "overflow" tube attaches to the pressure relief
valve. With the water heater off and the water inside it fairly cool open
and close this valve a few times. If that doesn't stop the leak then you
should replace the valve.

That should have been an earlier step. The do go bad, they do leak. Once
they start leaking they never stop.
