He may not have a PRV...
Both of my houses have had them, but one of my old neighbors in Duluth didn't have a pressure reducing valve! He wondered why he had to replace 3 water heaters in 7 years and finally discovered the contractor had left off that particular item. And in that neighborhood, we had 145 psi line pressure!
I had to buy a commercial garden hose for our front spigot because I was always rupturing consumer-grade hoses if I left the water turned on for more than 10 minutes.
Yup, Gwinnett has some damn high water pressure at the street!! When I lived in Norcross, my PRV gave up. My first indication was the pressure relief valve at the water heater started leaking. Of course, what did I do? Yup, replaced the valve. Still leaked! LOL It was doing its job.
I went out and got a gauge and attached it to the back water spigot and it read 135#!! Yeah, that was a bit too high. Replaced the PRV and dialed the pressure down to about 60#. Who knew those things actually went bad?!
