I replaced my fathers water heater and the copper pipe for the previous pressure relief valve comes out of the wall 3' up and was fine for the previous heater as the relief valve was on the top. The new one is on the side and not close enough to solder in some decent angles to get it hooked up again. I think it's pretty lame and probably not even code but what about putting some threaded ends on both pipes and installing a braided flexible hose? I currently have a pipe soldered on that goes straight down but don't want water to go all over the wooden floor and would rather have it go in the pipe which leads outside the home. Any help would be appreciated.
