As with your other thread, we need more info, more pics, broader view of the entire system, your thoughts, on what you see, and why you suspect something is wrong.

Very difficult to see in your pic, but it looks like a Watts valve (gas cutoff), not a pressure relief valve. Need a better pic to tell for sure. Did the WH have a TPR Valve installed?? If not, then it's is/should be a Watts valve. Also, that gas line could have been installed a whole lot better.

I thought it was a Watts valve. The connection can be used for pressure discharge pipe?
Thank you !

I see your post on the Nachi site, and have responded there also.

I guess I need to know what your definition of a "pressure discharge pipe" is??

The fuel line should be running from the main fuel supply, through the Watts valve, and then terminates at the WH control valve. There is no "discharge".

The Watts (cutoff) valve is typically installed where a TPR Valve is not practical for the installation. Where is the WH located at? Above a finished space??

Okay, that explains why the Watts valve was used instead of a TPR.

So the only question that remains is, was the fuel line run properly? If so, my only comment would be about the poor workmanship of installing the fuel line itself. Too long, and should be properly secured. Google CSST for a installation manual. Keep it in your files for future use and reference.

Okay... I'm outta here for tonight. If you have more questions, I'll be back tomorrow, if someone else doesn't get to it first.

Kyu,

Okay, the gas line connections themselves look good. My only concern now is the length of the gas lines, and their looseness. If memory serves right, the individual lines cannot be longer than about 3 feet. If that checks okay, then that should be it for the gas lines.

Now... do we get into the plumbing lines themselves? Was there a 'water' pressure release valve installed? It may not be at the WH it self, and can be located at another location in the plumbing, but there are restrictions to that. Did you Google the Watts valve? There is usually an installation guide which would be a lot easier for you to see the diagrams and understand.

First time, the WH has pressure release valve, but not have pressure release pipe. so I recommended install the pressure release pipe for safety reason.
The repair was done like that instead of pressure release pipe . other word, plumber installed 'watts valve' on the location for pressure release valve. I found no other pressure release valve and pressure release pipe.
 I've 1st time seen like that installation and very confused.
I have to respond for the safety issue.
Please advise. Thank you !

Recommend a qualified and licensed plumber evaluate the system for safety concerns as there does not appear to be a plumbing pressure relief valve installed on the piping as required for use with a Watts 210-5 NG cutoff valve.

No problemo!

Just remember, when doing an inspection, if you run across something that bewilders you, take lots of pics, close-up and a broad view, and gather as much info as you can. The more inmfo you provide, the better chance we have of helping you.

The contractor has sent information/documentation is implying that instead of the actual pressure release valve and discharge pipe, the watts shut off valve is sufficient in its place. Do you happen to know if this is correct/okay? Thanks again for your tremendous help!
