True - I was making the assumption that inspectors get some form of education or experience prior to entering the business.
I agree it should be shared (in fact I think this is the kind of item that we should be helping more consumers and homeowners become aware of since safety concerns like this exist in homes that may never be inspected.)
My reaction was more out of surprise that this would/could be an issue that some were uninformed about.
I was surprised. I had no idea there were 18 codes relating to just that one little drain pipe coming out of the TPR valve. The end of the pipe can’t be threaded? I doubt that anyone I’ve ever worked with including code officials knows about that one.
I agree. I have seen more than a few “professional” installations that were improper. In a few cases, it turns out that TPR disharges are an “apprentice” job and those guys are either not familar with the code, or they have 30 such jobs to do and rush to get them all completed.
re:TPR Inspection 101 items noted.
Number one: the tpr discharge is the WRONG size.
Two: NO discharge piping
Three: Bottom outlet inaccessible.
There are many others but these are the BIG three.
That’s an old style pressure relief valve. Newer construction now days have expansion tanks, normally installed above the water heater. Remember with the advent of anti-siphon valves and back flow preventers to the cities water supply, there’s no room for expansion any more. This scenario is caused by normal operation of a hot water heating system.
Last fall a water heater exploded in a mobile home and distroyed about of it. No one was hurt but they could have been. Many years ago I saw a film showing the results of a water heater exposion. The WH was 300 feet away and half of the two story house was spread out between. When it blew it went stright up like a rocket right through the house.
Oh yes! Open it up to the public.
On many job sites where union trades are present, the apprentices are the ones who have not yet been granted full status in teh union and, hence, get the grunt jobs. The union plumbers and pipefitters who have been in the trade for years are often good guys to know, as I have found them very willing to share knowledge and advice, and they are not likely to screw up anything as rudimentary as a TPR discharge line.
