said by leibold:yeah this has to be one of the dumbest T&P exits I've ever seen.. I can't see how a plumber would do this? It has no drain near by as it's a basement dirt floor. said by Subaru:
Ok so I will change that, but should I change the T&P valve as well?
Regardless whether or not you decide to replace the T&P valve, you should definitely attach a pipe to the exit of the T&P valve that directs any hot water escaping from the water heater safely towards the floor. I don't think it is required that the T&P output is attached to a drain but left as is it could spray hot water into someones face while standing next to it.
The output of my T&P valve (water heater installed by previous owner) pointed straight at an electric outlet (non-GFCI) without faceplate. It almost looked as if someone deliberately tried to make it as dangerous as possible (all three safety issues have been fixed properly).
