Pressure Reducing Valve 85 psi

The Watts LF25AUB-HP-Z3 is a lead-free brass pressure reducing valve designed for residential and light commercial plumbing systems. It connects via 3/4 inch FNPT threads and arrives preset to 85 psi. The unit meets ASSE 1003, CSA B356 and IAPMO standards for potable water applications.

Adjustment Range 75 to 125 psi

The valve regulates incoming supply pressure between 75 and 125 psi, providing headroom for typical municipal pressure fluctuations. It withstands a maximum inlet pressure of 300 psi and a maximum water temperature of 160 degrees Fahrenheit. Installations requiring pressure settings outside this range will need a different valve model.

Thermals Noise Power Draw

As a mechanical water valve, the LF25AUB-HP-Z3 operates without electrical power, fans or active cooling. It produces no operational noise beyond normal water flow sounds. The lead-free brass body handles thermal stress up to the rated 160 degree maximum without degradation.

Questions about this item

Will the 3/4 inch FNPT connections on this valve match the 3/4 inch copper piping already in my home?

Yes, the valve uses 3/4 inch FNPT x FNPT connections which are standard for 3/4 inch plumbing. You will need appropriate male-threaded adapters or sweat fittings to join it to copper pipe.

How can I verify the valve is regulating pressure to the 85 psi preset after installation?

Install a pressure gauge on a downstream hose bibb or faucet. With no water running, the gauge should read approximately 85 psi, confirming the factory preset is active.

Does the box include the pressure gauge or any strainer needed for installation?

The valve body is supplied alone. It has no integral strainer and no pressure gauge. Both must be purchased separately if your installation requires them.
