If you have a sump pump and it starts up, it will burn out very
quickly, they are water cooled. Hot water is not going to cool it.

a submersible pump, but not a pedestal pupm.

Not really. I run sump pumps on a regular basis up to a constant 16
hours a
day in 125 degree water and they last for years. I have another self
priming pump that will get rid of 190 degree water in a flash and has
been
doing so for about 15 years, but that is only about 20 to 30 gallons at a
time.

Zoeller spec is 130 degrees and most residential water heaters are right
in
that range.

But when the t&p valve blows for temp, it's 210 or more. Do they
blow for temp or for pressure?


If the temperature gets too high, it will increase the pressure and can blow
it. By the time it gets to the sump, the temperature is going to be down
considerably and won't be a problem. One of the uses I have for a sump pump
is for steam boiler blowdown. The valve is manually opened and the water is
212 as it hits the flash tank. The it is pumped up about 8 feet and over to
a drain. Most times is is a 20 gallon batch of water. This is done 3 to 4
times a week in winter. The pump was there before we bought the building 10
years ago and still works fine.
