3/4 in. x 3/4 in. Brass Pipe-Thread Water-Pressure Reducing Valve

Did realize how bad my existing valve was. Just finished install and better performing than my old one. Was concerned because a few other reviews said they had one fail... I'll update if mine does... But out of the box... happy I finally replaced my old one.

Pretty easy to install not being a plumber. BUT, you must have play in the pipes because you have to put the washer in between the inlet and the inlet seat properly or it will not seal. Mine is wide open against an unfinished wall. I had to loosen the nail in horizontal feed pipe strap above so I could push up on the vertical pipe the outlet was attached to (make sure you always re-tighten or it could vibrate, even silently and cause damage over time. My uncle was a plumber). You may need a plumber If the space it too tight and you cannot get it to give a enough. It's worth the money not destroying things you may not know how to fix. MAKE sure to use the white plumbers tape for the outlet and the seat (the round brass fitting the inlet sits on), for the inlet at the bottom if you do it yourself. I like the fact that the closed pressure is about 50 PSI and when I opened the faucets, etc. it stayed at a stable 40 PSI so there isn't lots of variance. The old one was all over the place and whined constantly, no more of that. I set mine to 53 PSI because of distance and number of outlets in the house. The output is from 40 PSI lots of water running to 43 PSI one faucet on which is safe enough for the appliances. It's worth the money if you can do it yourself.

Regulator installed easy on the first shot with with no leaks or leak-by. I was hesitant about the cheaper models with performance and leak issues according to reviews. This one is rebuildable and includes a removable strainer. Upon taking all of the regulators out of their boxes at the store, the overall quality looked better on this model than the others on the shelf. This also has a union on one end and uses female pipe threads which makes future removal and re-install easy.

Old plastic one failed this worked great

Works like a charm, replaced an identical one that was pushing 30 years old. That was still working, but I needed to replace the meter assembly, and it didn't make sense to leave the old one.

perfect match,and works excellent.

Easy to install if replacing existing unit in a easy access space. Simple to set pressure as well (with use of a pressure gage).

Worked like a charm. Went with the all metal version for durability.

I feel bad writing such a negative review. It took me a while to determine why my water heater pressure relief value kept triggering at 150 psi. After taking countless pressure readings, with the water heater turned off and on, I believe that I was able to narrow this issue down to a faulty pressure regulator. The issue was not the expansion tank. I noticed the pressure would creep up with the water heater turned off. For example, the house pressure would be set at 40 psi, then creep up intermittently to say 60 psi, then increase further when the water heater turned on. Unfortunately I do not know the incoming pressure from the City. I can only assume that it's higher, say anywhere from 80 to 120 psi. I believe what was happening is the expansion tank would fill up prematurely due to the higher that expected water pressure. This would render the expansion tank useless when the water heater turned on later. Just a theory. I replaced this Zurn with a Watts and the pressure now holds steady at 50 psi (when water is turned off of course). Also, the pressure barely increases (less than 5 psi rise) when the water heater turns on. I believe the expansion tank helps to limit the pressure rise when the water heater is on. I took the Zurn apart in an attempt to understand what could have gone wrong. After understanding how it works, I felt that the stem O ring may have been loose enough to allow for higher pressure water to leak just beneath the diaphragm and thus cause the house pressure to creep up. That's not good. When this happens, yes, the diaphragm shuts the valve even more so which is good. However, water is still leaking between the stem and O ring causing the house pressure to increase. Note I use the word "felt" because this assessment or conclusion may be completely wrong. While I am disappointed with Zurn and would expect a pressure regulator to last more than 1 year I am just happy that this is now fixed!
