My water heater has a 3/4" copper pipe from the T&P valve extending

case somethig happens.
Obviously it would be easy if I used some kind of flexible hose rated
for high temps. Is there anything wrong in doing it this way? How is
it usally done?

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.
