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?

What kind of floor do you have? If it's concrete I'd probably just
leave it alone. I've never seen one of those valves blow myself. I
have seen them develop leaks that you will not notice if you route it
into your sump pit. I have seen slow leak failures of hw tanks as
well as catastrophic failures. All were the tank leaking, not the
safety valve. If you want to do something to protect the floor area
of your basement I'd suggest a pan under your hw tank and route a
drain from it to your pit. The pan will cvatch the pipe as well.
