So I’ve been inspecting in 2023. I always measure the water temp at the sink since it usually doesn’t have a mixing valve or scald prevention/whatever like a shower does.
Now I know all you vets will scoff with my rookie numbers but for me on a HI, this one is hot. It probably peeks a few degrees higher than this I want to say I saw 148, but I was just taking pics.
Commercially, I saw this all the time and more at 180 degrees, but it was on equipment designed specifically for cleaning certain solvents and screens and it required special aprons, face shields, elbow length gloves and such.
This pic is for granny at the sink. Yeouch.
My thermometer is a commercial grade traceable. It’s rated as accurate to 1 degree C and in reality, it’s accurate to about .1 degree.
Certainly a safety hazard. Not sure of the year of the home or if it had one not properly adjusted but Temperature-actuated mixing valves have required in Florida since 2014 FBC. It’s a detail that many builders around here like to save money by not installing one at the water heater.
146.3°F is certainly very hot. That’s enough to cause some damage pretty fast.
My personal record was set last month at a fancy rental cabin.
you could pour water over a tea bag and have hot teat in seconds. Instant hot, no waiting. Scalding.
Curious, does it specifically say somewhere that they must be installed? The code you posted doesn’t seem to say they are required, only that they must meet certain requirements when installed?
P2724.1Temperature-actuated mixing valves.
Temperature-actuated mixing valves, which are installed to reduce water temperatures to defined limits, shall comply with ASSE 1017. Such valves shall be installed at the hot water source.
In 2010 they did not include that language.
