Received quickly and the product was a perfect match. Installed easy and works perfectly.

Well Made, easy installation.
This is an upgraded version of the one it is replacing. It is a heavy duty brass, machined and threaded. It is serviceable and adjustable. Mine holds a nice steady pre-set pressure at 48 psI. I recommend this. I did the install myself. Good choice.

Pressure gauge review
Water heater loved it and so did I. Water pressure returned and works perfectly.

Perfect fit-had all its parts too!
I didn’t need the union as mine fit the new one so that saved me some soldering. Fit perfectly and had all the o rings and parts, I only needed teflon and a plumbers wrench. So happy to have a working PRV again. Installed in less than 30 minutes (drain time included) and it’s great quality and quiet when in use.

Was a perfect replacement for an older water pressure regulator
This part fit perfect without modifying the pipe. The only concern was that it only came with one fastening nut. Lucky for me the existing nuts fit so I used them. It fixed my noisy pipes and high water pressure.

Great price.
I had no problem installing product in my dads house water pressure had gone to 130 lbs before new one put in. Great price compared to what plumber would of charged. Good thing I am a pipefitter/plumber. I knew what the problem was.
