Watts is relatively new in this market that is dominated by a single brand. I chose the Watts because I was happy with their RO system and it had a stainless adjust bolt

Easy to install, easy to adjust, solid
Installation took me several hours because I failed to realize that my outside faucets bypass the water pressure regulator, and the water pressure meter I bought lacked an adapter to thread into the kitchen faucet. Installation was easy, but I saw no change in water pressure. Eventually I figured out that I had to test the water pressure inside the house, not at the outside faucets. Once I got that set up adjustment was easy. A plumber installed one of these twelve years ago. This year my reverse osmosis water filter sprang a leak, plus other stuff had small leaks. The old water pressure regulator was done for. Now that I have a water pressure meter I'll check this every year.

    Dude, this thing works.
    So my wife tells me the water pressure seems a little high. I immediately call the water dept who comes out and checks it at tells me it's 192 psi, and my pressure reducer isn't doing squat. I freaked out. Called everyone, no one could come. Of course if you've ever been without water you know how miserable that is. Made the run to Home Depot. I've never done anything like this. This thing was easy to install and it essentially fit into the exact same space where the old one came out of. It probably took me an hour to remove the old one and install this one...but IT WORKS. So happy to turn the water back on 55 psi. YESssss....

      This Watts pressure reducing valve was exactly what I needed to replace a 10+ year old Watts PRV that had failed letting 150 PSI into my house plumbing. The failed PRV was causing my plumbing to squeal loudly any time a faucet was turned on. I realized that the pressure was much higher than normal and tested it with a pressure gauge to confirm the PRV failed. It was a direct replacement and having the union and female threaded side allowed me to replace my old PRV in 20 minutes without having to do any soldering. The new PRV works flawlessly and reduces the 150 psi street pressure down to 50 psi. This PRV has the ability to adjust the pressure from 25-75 PSI, but the factory preset of 50 psi works great. I love the fact that Watts has kept the dimensions of this PRV the same to make replacing very easy. Just shut off the incoming water either at the meter or at the house shut off, drain the lines, loosen the union and back off the male adapter. Be sure to have a wrench on the male adapter when taking off and installing the new PRV to prevent stressing the house plumbing. Make sure the O-ring is on the union face, tighten the union and test for leaks. Saved myself several hundred dollars by doing it myself.

      Works Great and Can Be Easy to Install
      My previous pressure regulator failed, and I replaced it with the cheap $59 Shark Bite unit from Home Depot. It would not hold pressure, so I returned it and spent a little more for this regulator. It holds pressure just fine, and seems to allow greater volume of water to flow through it. As a hint, I also bought two Shark Bite adapters to thread into the unit’s outlets, and a Shark Bite slip coupling. With these three extra pieces, install took about 10 minutes. I suggest you consider spending the extra $20 or so for these upgrades.

        Install of the pressure reducer went as planned so far as that component was concerned. I wish Home Depot sold the double-union version of it, as that would have been considerably appreciated for this project's application, where the existing pipe was located too close to the wall to spin the body off/on the male pipe adapter.

        Well built pressure reducing valve but there is a design flaw. The union leaks. The O-ring in the union is too thin to hold supply side high water pressure; my supply pressure is 150psi. Other competitors use a think rubber gasket but Watts use a thin o-ring only. It's too thin. Applying teflon sealant on the o-ring stopped the leak temporarily but I don't think it can be a permanent solution. Other than that, it's a good valve. Water pressure and flow rate is good. I purchased a double sweat union model (3/4" LF25AUB-S-DU) at a local HomeDepot. It's not listed on website but local stores stock it. Double union model is easier to install and cheaper than FPT model. It's made in China.

          Failed after 28 months
          Purchased Watt 3/4 inch FPT x FPT brass pressure reducing valve from Home Depot in May 2014, I installed June 2014 at my home. In October 2016, received water bill for $120 more than usual lead me to discover the unit failed. The valve is located on a heavily wooded portion of my lot, and I was surprised to see a swamp on this rocky hillside next to the above grade install of this valve. Hope no neighbors get zika they will be mad at me! The leak occurred where one of several small bolts holds the upper and lower portions of the valve together (see uploaded photo of active leak). The piping is all PVC; so its not metal induced corrosion. This was a residential water service in San Antonio suburb where service side reaches 120 psi. Only 1 year warranty from Watts. Im looking for another brand to replace. See image of water spraying out of valve! I contacted Watts via website and asked if they would stand by product in some capacity; I dont anticipate hearing back from them but if I do I will update review.

          Should've bought sooner!
          The pressure regulator performed better than expected. Easy to adjust pressure due to seamless construction. My hubby, not a licensed plumber, was able to install without a hitch. Replaced one that died an ugly, wet death. Easy to read model numbers without squinting.
