In both upstairs and downstairs bathrooms, whenever we flush the
toilets, and then immediately go to the sink to wash our hands, the
water coming out of what is supposed to be the cold faucet is very hot.
After about 30 seconds, it will go back to cold.
Recently, we had a flood in our upstairs when the black floating ball
in the tank of our toilet broke while we were not home. 80 gallons
were deposited below. When repairing the toilet, the plumber noted
that there was hot water filling up our tank.
Does anyone have any ideas for these two things to be happening? I
don't know if they are related or not, but I am open to suggestions.
The plumber thought that the filter in the shower might need to be
changed and could be causing the issue.
Thanks in advance,
Could be feedback from a water heater connection.
But can also be caused by faulty Single-Handle faucets
or by a washing machine inlet solenoid valve.
Try and isolate fixtures like these (byclosing shutoffs)
and see if the problem disappears.
If not, then look for more complicated causes.
I replaced the filter in the shower handle yesterday, but it didn't do
any good. I also turned off the water to the hot and cold on the
washing machine but I still got the same response. I am leaning towards
having an expert come out and examine.

Check to see if your toilet supply was plumbed to mix a little from the

from sweating on the outside if the humidity is high.
It might have been done that way and has gone out of adjustment.
Though I'd more likely go with the suggestion that you see if the hot
water filling the tank stays hot for a couple of minutes of flow by
holding the flapper up by hand so the fill valve stays open and water
keeps flowing in. That'll give you more to go on. If it stays hot
continuously after the sink water cools down you've got more to look for.
I once ran into a toilet which must have been installed by a drunken
worker. It WAS fed from a hot water supply line, and I guess no one
noticed it until after they'd closed up the wall.
Something about your story bothers me though. Did your plumber explain
how the hell 80 gallons of water "got deposited below" because the float
ball broke? Isn't that just what the overflow tube in the tank is there
Did the ball break off its arm and then manage to float around and end
up covering the top of the overflow tube, thus blocking it off? That, or
a badly clogged drain is about all I can think of which would cause that
"water deposition" event to happen.
That brings up another situation. If a faucet is shutting off flow to the
sink, but leaving an opening between the hot and cold chambers you could get
a mix also. Since the toilet is on the same line to the bathroom, it may be
getting a dose of the hot water. That situation came up here a few months
Thanks for the response. I too was very skeptical of the overflow tube
not catching the water. I have been told that some plumbers will
increase the water flow into the tank to make it fill up quickly, but
when they do that, it exceeds the capacity of the overflow tube. Of
course, your two causes might be to blame as well. An engineering firm
now has our toilet and is preparing a report for the insurance company.
I will say that the exact same thing happened down the street to a
family which had the same builder and the same plumber as a
subcontractor. I am hopeful that something might come out of
I have a similar situation but it's not a problem. The cold water line
runs across the top of the main furnace duct in the basement. In the
morning, the cold water will run hot and then cold. The same water has been
sitting on the furnace duct all night and gets warm and that little segment
of hot water moves through the pipe and out the faucet as soon as the water
is turned on in the morning.
Only happens in the winter when the furnace is going.
If the pipes are in the ceiling the heat in the attic is causing the water
sitting in the pipes to get hot. If there was a cross connection the water
would stay hot not cool down. The same thing happens in my two upstairs
bathrooms. Dose the water stay hot filling the toilet ? Pull the cover off
the tank and check. I will bet it cools down.
