The last question is key. Also keep in mind that if it should open
for any reason, there is also the possibility that it may not fully
close again. It's not uncommon for this to happen if you open/close
it for testing. Sometimes you will get some continuous leakage and
wind up replacing the valve.
AFAIK, code in most areas says there has to be a pipe from the TPR
extending down to within a certain distance (6"?) of the floor.
Whether you want or need more than that depends on where the water
would go and what damage it could do. And at the same time, I would
consider where the water from a tank leak would go. Also consider one
of the $10 water alarms, which can give you a heads up, especially if
the heater is somewhere that it will go unnoticed.
