Technically, if the pipe going to the left is just a pipe going nowhere, it would work still. The PSI in the water heater is the same as where the TPR is.


Even though all water heaters now have a port on them, thats how they did it when the old water heaters didn't have a TPR port on it....

Notice the serious corrosion at the shut-off.

Yeah.... it all needs to be redone. I mean, technically, it doesn't, but if it was my house, I would.

The pipe you are referring to is the discharge pipe.

The real problem here is two-fold. 1) There is no temperature protection and 2) considering the orientation of the PR valve and the corrosion, there may not be pressure protection either. PR valves can and will rust to the point where they will no longer function.

Still, it might work

If my memory serves me, a gas fired water heater is an ASME “direct fired” pressure vessel and therefore requires a pressure relief device to be mounted directly to the vessel.

Did one the other day, the “tenant” had replaced the TPR valve, it dripped, so he fixed it by putting a water hammer arrestor on the end of the TPR valve.


I made him take it off while I was there.

Yup, it stopped the dripping. Of course, so did removing the WHA and tightening the TPR valve a little bit.

Actually it won't and it is very dangerous. There is a reason the T&P valve has to be located in the top 6" of the tank. In a configuration like this one the temperature in the tank can reach in excess of 300 degrees before the temperature of the water in the pipe reaches the threshold of the valve. Then it goes boom.

He should of just put a galvanized plug in it
