I had a situation that this house is located in the mountains and the city was raising the water pressure in order to get the water to the top of the mountain. With the pressure guage I purchased with this regulator, I found that the water pressure was rising to 160Lbs. and sometimes more. This was causing the popoff on the water heater to bleed off pressure over 180 the rating of the valve loosing hot water. Also faucets would leak when there wasn't a problem with them. Installing the regulator was somewhat easy. I cut into the existing copper line under the house. I added the adapters that will make it easy to just unscrew the unit if I need to replace it for some reason. I also added a valve past the regulator so that I could attach my pressure guage to check the pressure before I crawled out from under the house. I have tested the pressure over and over and it is working great.

I used this product on an incoming water main line to our residence with input pressure of 80psi and I wanted to reduce it to 54psi.

I like the product and it appears well build and durable. However, the first two units installed were defective from the factory and they would allow outgoing pressure to "creep" from the 54psi setting all the way to 75psi within an hour.

Upon the installation of the third unit the pressure has been holding precisely at 54psi now for the past couple of months and all is well.

It just took me the time and effort to install three units to finally get a good one which we now have installed.

When the city boosted water pressure for the freezing months. Flush valves started leaking. Installed on main cold water line and problem went away. There is still plenty of pressure and volume for all normal functions.

The old one in our home went bad and discovered Supplyhouse.com. They had a great price so I figured I would give them a try. Fast delivery, great price and correspondence was great. Valve dropped right in and I'm back to a manageable pressure in my home.

Comments about Watts 1-1/4" 25AUB-Z3 Pressure Reducing Valve, Lead Free (Threaded F Union Inlet x NPT Threaded F Outlet):

A good product, but it seemed to reduce the flow as well as the pressure. I replaced it with a 1 inch Watts valve and the difference is substantial. Could be a port issue.

Brass pressure valve

Comments about Watts 1-1/4" 25AUB-Z3 Pressure Reducing Valve, Lead Free (Threaded F Union Inlet x NPT Threaded F Outlet):

We live in rural Arkansas. We installed a water line from the city line to our house (1000 feet)of 2" PVC in 1984. It needed replacing and we did the job with ProPex 1-1/2 pipe placed inside the old PVC. In the process, we replaced the 4 pressure regulators (subject of this review). All of the needed replacement parts came from Supplyhouse.com. Their items, shipping time, cost, and support were all 5-star!! The quality of these valves was superb as were all the ProPex parts. Highly recommend!

Installed easy, holds the pressure very consistent. Easy to adjust. What else is there to say, it reduces the pressure. I had 90 PSI comming into my house and have it adjusted to 60 PSI now. Plenty of pressure for the home.

I would recommend to others.

  • Q:

    does this unit have a relief bypass?
    Asked on 4/26/2016 by bill from stuart,fl.

    1 answer

    • VERIFIED BUYER

      A:

      Yes, the standard bypass feature permits the flow of water back through the valve into the main when pressures, due to thermal expansion on the outlet side of the valve, exceed the pressure in the main supply.

  • Q:

    If the pressure on the exit side exceeds the pressure on the inlet side will the flow be reversed. i.e. Will this valve allow a backflow to occur?

  • Q:

    What is the maximum flow rate if I reduce the outlet pressure to 50 psi?
    Asked on 9/5/2015 by marc249 from Prosser, WA

    1 answer

    • VERIFIED BUYER

      A:

      That depends on your input pressure. At 75psi input pressure, a 2 inch reducing valve is spec'd at 95 gpm. However, it tails off quickly. At 65 psi input, you are looking at only 45 gpm. If you need more, I would recommend you look at the U5B series where at 65 psi input you would get 85 gpm. There is a big difference in these valves and I always recommend the U5B series over the 25AUB series for just about any application.

      The instruction manual states "To adjust pressure setting, loosen
      the lock nut and turn the adjusting bolt clockwise to increase pressure, counterclockwise
      to decrease pressure." The manual can be found here on our site :
