It does in my state of GA.
Works in MN!
In your case, no, because it looks like it is reduced to 1/2" pipe.
It needs to be 3/4 all the way through, and the pex fitting for 3/4"line is actually about 5/8", so even a 3/4" pipe may not meet code
Is it okay that it’s connected directly to the valve? the UPC says something about no pex or pert within 18" I thought. is that only tank heaters?
In Florida (and any other area which bases their local Codes on the ICC), PEX (or other flexible piping has several requirements).
Reference FBC Residential 2017 2020
The discharge piping serving a pressure-relief valve, temperature relief valve or combination valve shall:
1.Not be directly connected to the drainage system.
2.Discharge through an air gap located in the same room as the water heater.
3.Not be smaller than the diameter of the outlet of the valve served and shall discharge full size to the air gap.
4.Serve a single relief device and shall not connect to piping serving any other relief device or equipment.
5.Discharge to the floor, to the pan serving the water heater or storage tank, to a waste receptor or to the outdoors.
6.Discharge in a manner that does not cause personal injury or structural damage.
7.Discharge to a termination point that is readily observable by the building occupants.
8.Not be trapped.
9.Be installed to flow by gravity.
10.Terminate not more than 6 inches (152 mm) and not less than two times the discharge pipe diameter above the floor or waste receptor flood level rim.
11.Not have a threaded connection at the end of the piping.
12.Not have valves or tee fittings.
13.Be constructed of those materials indicated in Section P2906.5 or materials tested, rated and approved for such use in accordance with ASME A112.4.1.
14.Be one nominal size larger than the size of the relief-valve outlet, where the relief-valve discharge piping is constructed of PEX or PE-RT tubing. The outlet end of such tubing shall be fastened in place.
That’s going to pertain to the supply and outgoing piping, not the TPRV.
The PEX is undersized. PEX is a problem period. PEX is the new poly, mark my words.
PEX had been around since the 80’s. I am not saying it won’t have problems, but it will likely be fitting related IMO.
There are several class action suits regarding PEX in motion. It will be the new poly, plastic is not a good choice for supply plumbing.
Even Cpvc has issues, especially when in a hot Florida attic. It gets very brittle.
I happened to just barely step on one in an attic a few months ago, and water started spraying everywhere.
Luckily it was over the garage, and my son was right there at the ladder, so he had the water turned off after just a few seconds.
Had to pay a plumber couple hundred bucks to come fix it, but could have been much worse! I thought it snapped on just one joint, turns out it was 3 different places!
(I would have just fixed it myself, but didn’t think that would go over well with the seller and realtor)
Oh man, I’ve been down this road twice… once I did it, once it was one of my inspectors. Both under the same circumstances - in an underfloor crawl space sliding along with our backs touching the insulation, hit a low point drain buried just above the bottom of the insulation. I swear, sometimes you just look at CPVC wrong and it starts leaking!
As for OP, I have no problem with Pex for a TPR but the non-rigid type pipes are usually required to be secured at the bottom to prevent them from whipping around and spraying scalding water. I can’t remember if that’s a code or just manf. recommendation but just seems like a good idea in general.
Sure that PEX TPRV tubing is wide enough?
As well, CSST bend radius is suspect.
That looks like an appliance connector to my eyes, and not CSST. CSST is a lighter shade of yellow and the ribs are spaced further.
You don’t know what you don’t know, until you know it.

Actually, the new evidence shows that the plastic pipe is failing, not to mention the issues with the fittings.
Yep I agree. Until the cases are resolved. Example.
Look at the screenshot I posted. It’s in the code that the PEX must be oversized AND secured.
Your eyes are not wrong…
