Our 60 gallon electric hot water tank only had enough hot water for
one bath, so the plumber drained the tank and replaced a defective
We had enough water for 2 super hot baths that night, then ONLY cold
was left. And the tank starting leaking on the floor that night,
although dries up during the day.
The plumber next replaced a gasket thinking that would stop the leak,
and pressed the reset button. We again had super hot water for 2 baths
ONLY that night. We pressed the reset button ourselves before bed, and
again had leaking water around the tank overnight which dried up
during the day.
The plumber came back and replaced the thermostat. The water isn't so
boiling anymore, which is good, but we still have a problem with the
tank shutting itself off after the evening baths, plus there's water
on the floor in the morning.
When the tank's panels are off i can see that the yellow insulation is
wet. I'm assuming this is what keeps shutting the tank off forcing me
to reset every evening.
What do I try next? Do I need a new tank? Is the water I see just
leftover water from the bad gasket/super-heated water problem? Will it
dry up on it's own after a few days? I assume the water is what's
shorting the system and shutting things down. But why is there only
water on the floor overnight and not during the day?
Anyway, advice I could bring back to my plumber as a suggestion (or to
a new plumber) is appreciated.
Without seeing it, or knowing how old it is, it's impossible to give
much advice. If the tank was properly drained, there should only
have been a tiny bit of water when the element was removed, not enough
to get the insulation soaked with a lot of water. Did you check for
any visible leaking around where the element was replaced? And even
if the insulation is wet, I doubt it would cause the circuit to
trip. If the insulation is wet, I'd leave the access covers off
until it's dry and make sure the wet insulation isn't on top of bare
I guess since you're already into this guy for an unknown amount, you
should call him back again. But I wouldn't pay him anymore unless
it's clear that whatever is going on is due to some other problem
cropping up that he isn't responsible for.

The tank is roughly 5 years old... I read elsewhere that if the water
is super hot (and it was), that can cause leakage. The thermostat was
apparently shot, but even after replacing it I assume the damage would
have been done and any water that seeped into the insulation would
have to evaporate. it's just weird that I only get seepage overnight.
I think it's either time for a new plumber or a new tank.

Let's see. You have a 5 year old tank. It didn't leak before the
plumber did some work. It leaks now. Simple - he screwed it up or
didn't install something right. As to the soaked insulation - it is
ruined. As well jacketed as it is, it is highly unlikely to ever dry
out again. He should be stuck for a new tank and crossed off your
list of people to call in the future.
There may be hope for the insulation, since it is around a heated
tank that will cause the moisture to go into a vapor state. Need to
leave the covers off the t-stats to allow it to happen. Might even
carefully make a drilled hole in the base of the metal shroud to
clear and accumulation if it isn't able to leak out, but from the
description, that's been able to happen.
No, I don't think the HWH needs to be written off as a loss, but
the same does not apply to the plumber.

I think a NEW plumber is in order. Hell, you probably spent the cost
of a new heater on call backs by now.
If you are handy, just buy a new heater, install the two pipes and the
electric wires and be done with it.
However, if you are handy, shut off the electric. Look for the
location of the leak. It's probably the gasket by the element that he
replaced. There is likely rust under the gasket and its not ever
going to seal tightly. But, if you pull the element out, and coat the
gasket with hi-temp silicone (red stuff from auto parts store), then
reinstall it, you will end the leak. Do leave it sit overnight with
out water pressure though so the silicone can dry. I should mention
if it's rusty around that gasket, the tank wont last much longer.
If there is a pinhole in the tank itself, its time for a new tank.
Why it only leaks at night is beyond me.....
Maybe there is a ghost in it???? :)
Wait a minute.
There are two thermostats for an electric water heater. Both of them
need to be set for about the same temperature, maybe a little
different to acomodate stratification.
element. Then another visit, replaced a thermostat. And there
is still a leak.
What does this pattern suggest to you?
If he were working on my car, would a similar pattern emerge?
And you might want to check the last two numbers of your serial
number, they may indicate year of manufacture. An electric water
heater should be good for about 12-13 years.
