Water heater hookup...need advice.

[David Nasser]

The Gas line ran from the wall to the TPR valve the back to the
water heater.....Looks illegal from my training. Need feedback.

It's a Watts 210 gas shutoff valve. This is a proper installation.

Thanks Jeff....

Interesting.
I've never seen one of those.

Goes under the heading "unusual" in my files.

Make sure there is still a properly installed TPR designed to 210 F/150 PSI and downspout six inches from the floor OR DRAIN This is primary protection and not to be mistaken with this set up of a WATTS 210 gas shut off.
Changed to prevent confusion.

Please show us where that is a requirement

[KEVIN WOOD]

I will let a plumber chime in and explain. If no one does and you can't figure it out look at the instructions for installation.

A TPR valve is not required however a pressure relief valve is. It is usually located near an exterior hose bid. The watts 210 shuts down the gas in an over temperature situation and the pressure relief valve opens in an over pressure situation. They work together and must both be installed

The watts 210 and pressure relief valve replace the TPR set up

So who is right? Kevin, did you f u c k up again?

[KEVIN WOOD]

We call it a TPR in Canada. Temperature/Pressure Relief Valve.

TPR valves have a temperature probe that must extend into the water heater tank, they work on temperature and pressure thus the name. Pressure relief valves work on pressure only.

TPR valves and pressure relief valves are two completely different things.


In my area Watts 210 valves and pressure relief valves are found on interior water heaters where a traditional TPR and drain line will not work (drain to the exterior)

Correct - a TPR valve is a combination temperature & pressure relief valve - which is not required when using a Watts 210 gas shutoff valve.

A standard pressure relief valve is required to be used in conjunction with the Watts 210 gas shutoff valve.

Intallation specifcally requires a pressure relief valve
