About this item

  • LEAD-FREE WATER PRESSURE REDUCTION: The Watts 3/4" Lead-Free Water Pressure Reducing Valve is installed at or near meters to cost-effectively control water pressure flowing to appliances and outlets in commercial, industrial, and residential applications. This assembly includes an NPT threaded union female inlet by NPT female outlet connection, a removable integral stainless steel strainer, thermoplastic seat, bronze-sealed spring cage for accessible outdoor waterworks or pit installations, and thermal expansion bypass.
  • EASY INSTALLATION AND MAINTENANCE: This lead-free water pressure reducing valve is designed for straightforward installation with easy handling and in-line serviceability, featuring a thread union by NPT female connection that simplifies the installation process.
  • THERMAL EXPANSION PROTECTION: The valve includes a bypass feature that effectively controls thermal expansion pressure, permitting 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. It has an operating temperature range of 33° F (0.5° C) to 180° F (82° C).
  • VERSATILE PRESSURE ADJUSTMENT: This valve is suitable for pressures up to 400 psi (27.6 bar) and allows for an adjustable pressure range between 25 to 75 psi (172 to 517 kPa), with a standard setting at 50 psi (345 kPa).
  • EVERY DROP COUNTS: Water. It's in our name and close to our hearts. Since 1874, Watts Water Technologies has been delivering innovative technologies that make the world's most precious resource safe and accessible.

The 3/4 in Lead Free Water Pressure Reducing Valve assures rapid response to pressure changes and maximum flow with minimal pressure drop. Complies with all lead-free installation requirements. Temperature range of 33 to 180 degrees F (0. 5 to 82 degrees C). Suitable for accessible outdoor waterworks or pit installations. From the manufacturer: Calculations show pressure-reducing valves can save as much as 30% on domestic water heating costs, prevent water waste and perhaps even lower municipal sewer usage fees.

Exelent.. better then what I expected. My house was built in 1973 and this product matched the original piece. Also as describe was set at 50 psi of pressure. Resolved the shaking pipes problem.

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.

Perfect replacement to the one that was faulty at our new house. Took about 1 hour and fixed our high water pressure issues. I would recommend you get a water pressure gauge to make any adjustments and verify correct pressure around 60psi.

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.

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.

This product works as It should. In the description it said it was set for 45 psi and I tested it after it was installed and it tested 45 psi, so that was a plus. I installed the only yesterday so it is too early to to say how long it may last. But, as these go, they are pretty dependable. Amazon asks you to rate a product before you get to accurately test. Happy with it so far. Also, in the description it listed the dimensions way wrong. It is not that large. It about the same size as most water regulators.
