## Overview

The Watts 0009257 25AUB-Z3 is a robust 0.75-inch bronze water pressure reducing valve designed for pressures up to 300psi. Featuring lead-free construction, an integral stainless steel strainer, and a sealed spring cage, it ensures reliable, adjustable pressure control (25-75psi) with easy in-line servicing and thermal expansion management. Ideal for professional-grade plumbing systems requiring durability and compliance.

## Description

Series LF25AUB-Z3 Water Pressure Reducing Valves are designed to reduce incoming water pressure to a sensible level to protect plumbing system components and reduce water consumption. This series is suitable for water supply pressures up to 300psi (20.7 bar) and may be adjusted from 25 – 75psi (172 – 517 kPa). The LF25AUB-Z3 features Lead Free* construction to comply with Lead Free* installation requirements. The standard setting is 50psi (345 kPa). All parts are quickly and easily serviceable without removing the valve from the line. 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.

Review: My house was built in 1966 and had a Watts 3/4" U5B series pressure reducing valve. According to the Watts website, the U5B is a higher performance/capacity model than this LF25AUB-Z3 3/4", and comparing the charts on the volume @pressure, there does appear to be a difference, but it looked small at the pressures that represent my operating environment. My old U5B was no longer regulating pressure, and so everything in my house was being subjected to 120psi that comes off my street. This is relatively close to the 150psi safety release on the hotwater tank and it was wreaking havoc with anything less than contractor grade garden hoses (blowing them apart after a few months in service). I became concerned that the high pressure might also destroy a toilet/sink supply line and in the worst case, flood the house while we were gone. I tried to get a repair kit for my U5B and by all accounts I ordered the right kit, but none of the parts fit. Maybe someone accidentally swapped the parts bags between two kits while comparing, or maybe the U5B I had was so old that the design had changed a bit. For whatever reason, the bell housing dimensions on my U5B did not match the dimensions specs noted by Watts. Even though "3/4" was clearly forged in the side of the valve and the sticker on it clearly read U5B. Anyway, I don't know if the old valve was Lead-Free or not. So I decided it was worth it to just order a new valve. The direct modern replacement for the U5B is going for around $300 +/-, depending on your source, and desertcart didn't have any sources. But the LF25AUB-Z3 3/4" was $80 shipped to my door. So I took a chance and ordered it. Installation was a breeze, turned off the main supply, opened a sink to bleed the pressure off the system, shut off the hot water heater, then just backed off the old unit and put the new one in. The new one is maybe 3/16" shorter in overall length, but there is plenty of slack/give in the copper pipes I have to allow for some differences in size. It's amazing the difference this has made for my appliances and what not. We used to get pretty bad water-hammer, installing arresters helped, but did not eliminate. With the new pressure reducing valve in place there is no more water hammer, my automatic icemaker is working clog-free, and the refrigerator door water dispenser works much better. I may miss the 120psi when it comes to working outside, but so far I love the new pressure and there is room to turn it up a bit. The valve comes factory preset to 50psi and can be adjusted up to 75psi. I don't recall the lower limit. Oh, and I took the old valve apart. To my surprise the diaphragm was perfectly intact. What had failed was the bypass valve. It appears to have rotted/worn away small enough to come apart and it got trapped by the screen. And another interesting fact was that I'm quite sure that screen had never been checked in the 49ish years it had been in service and it was perfectly clean, pretty cool.

## Questions & Answers

**Q: Where this product is manufactured?**
A: It’s assembled in USA.

**Q: where is the stainless steel strainer located?**
A: The strainers are located inside , which is accessible through the two caps on the bottom!

**Q: Will the PRV work in a vertical position ?**
A: It should, it is spring loaded mining it works with water pressure and spring pressure to control the flow

**Q: how many turns is needed on the adjustment bolt before you notice a difference in water pressure ?**
A: The range on this pressure reducing valve is 25-75 PSI with 300 PSI maximum pressure as you turn the adjustment screw down(clock wise) you will see the change pretty rapidly since the amount of threads are not that many, the key is to have a pressure gauge visible so you can watch the PSI go up & down, what you do is add tendon on a coil spring internal!

This was a "drop in" replacement for the original water pressure regulator in my house. The original was 28 years old, and had a pinhole leak in the diaphragm, so could have been repaired. But the new one went in as a replacement in less than 10 minutes, so water was up and working again very quickly. No one actually noticed the water was off , as it was so quick. And the new replacement works perfectly.
