Can you post the code that requires a PRV and expansion tank be installed together. I’ve never seen it. I’m always willing to learn new things.

How do you like that stupidity in the SOP?

A domestic potable water supply pipe pressure relief valves are used when the water pleasure can exceeds 80 PSI in many jurisdictions if I am not mistaken.
UpCodes: 608.2 Excessive Water Pressure
Where static water pressure in the water supply piping is exceeding 80 psi (552 kPa), an approved-type pressure regulator preceded by an adequate strainer shall be installed and the static pressure reduced to 80 psi (552 kPa) or less.
Ball valves are not pressure relief valves or pressure regulators.
Might just be me but, A: the position of the stainless steel clinches on the plastic elbows and other fittings appear to be suspect.
B: The exposed domestic potable water supply pipe to the right of the stringer is prone to accidental mechanical damage.
C: The stainless steel hose clamps on the plastic pipe to PEX pipe fitting transition are amateur connections.
UPC 608.3
But there are many municipalities that adopt their own codes. But most will require an expansion tank on a house with a closed system. Just check your local codes.
I’m curious do you normally quote UPC codes when your state follows IRC codes? Of course the code you reference does reference a closed system with a tank type water heater.

I never quote code in my report. It was easier to look up UPC code on my phone than my local city code.
And besides it’s a safety issue. I would rather the water expand into the expansion tank then into the water tank and blow the tpr or bust a pipe joint or fixture.
It’s a non-issue with a tankless water heater. It’s not required by the manufacturer. But you want to recommend one in your inspection report you do you. Have you ever considered asking a licensed plumbing contractor their opinion?

I never said anything about a tankless water heater. I’m not sure where that even came from.

Okay maybe I did, sorry I recently had spine surgery that failed and I am taking gabapentin, which makes me forgetful and a bit hazy in the brain. It’s medicine that’s is supposed to work in the brain to help with nerve pain. My next surgery on October 14th is going to be a 2 level TLIF fusion on my L4 thru S1. Removing 2 disks, adding spacers to restore height, then they are adding Rods and screws.
Here is a photo of my MRI from 2010 and then may 2024.
All the white crap in the second pic is scar tissue highlighted from the contrast dye, from my surgery in March 2024. That was a failure. The Dr. Removed bone to relieve pressure on my spinal cord. All it did was destroy my muscle in my back.
