Well someone just did, I think (I read it 6 hours ago), in this very
People also told bad stories about trying to replace the valve. I'm 67.
I forget what their problems were!
This all matters if there is a relationship between draining the tank
and not having a leak. That webpage someone posted talked about hot
spots caused by sediment, and holes caused by hotspots, but that applies
only to gas wh's. Electric wh's have the heating element in the midst
of the water, no flames at all (on a good day), and even the problem
with sediment covering the heating element was just...... I don't
remember but it wasn't a leak I don't think.
The solution for a big leak when you're away is a pan with a drain that
Ironically, if you had no pan, and it leaked a little at first, you'd
have a better chance of seeing it, especially if it ran out under the
door. But by having a pan with a drain, I think it's much less likely
someone will notice that first small leak.
They also make water detectors, that buzz when the water reaches the two
contact points. I had one in the laundry sink for a while withthe
buzzer under the kitchen sink. Got to be two much trouble to change
When I had an initial small leak, it was right after the condensation
from my AC had driblled all over the laudry room basement floor.
Usually that amount of water dried in a day or two. It didnt' this time
but I didnt' put 2 and 2 together until several days later, I got a
flood, though just in the unfinished room. After that I put in a pan
and ran a plastic pipe to the sump, so the sump pump will pump away any
water from an initial slow leak, and maybe from the bigger leak that
comes later. Though I really have no idea how fast that leak is. Does
it really jump up from slow to fast without going through a little
faster and a little faster yet. Of course I might not notice that
either. Maybe my 2" pipe will be enough, even at maximum leaking.
I wasn't referring to you about the snide remark. It was the poster who said
something about my IQ. Sorry I should have clarified that. If draining is
not necessary unless the unit fails then I won't bother with it. The hot
water supply has been a little wonky lately though, kinda small sporadic
interruptions in the flow but nothing serious.
Thanks for the advice about a ball valve. I will certainly use it when the
How high is the drain pan?
How high is the spigot?
How much bigger than the diameter of the WH is the diameter of the pan,
where the spigot is? EVen if the hose goes down at first and then UP
to go over the pan lip, as long as the end of the hose is lower than the
water level in the WH, the WH will drain.
But why do you want to drain it? What problem do you hope to solve?
Everyone here says that's a way to get sediment in your spigot so it
won't close anymore.
