The WATTS BRASS TUBULAR 3/4 LFN45BM1-DU-EZ-GG is a lead-free water pressure reducing valve designed to regulate and maintain consistent downstream water pressure in potable water systems. Built with NPT-threaded double union female connections at both inlet and outlet, this valve allows for straightforward in-line installation and removal without cutting pipe. The adjustable pressure range of 25 to 75 psi covers the most common residential and light commercial service requirements. A built-in gauge tapping port accommodates a 160 psi gauge, giving technicians a direct read point for pressure verification during commissioning and service calls. Licensed plumbers working on domestic water supply systems are the primary installers of this valve.
This pressure reducing valve is suited for residential and light commercial potable water supply applications where incoming street pressure exceeds the safe or code-required range for building fixtures and appliances. The double union design makes it well-suited for retrofit installations where service access is limited, allowing the valve body to be removed and reinstalled without disturbing the surrounding piping. The gauge tapping port adds value in applications where ongoing pressure monitoring is required or where local codes call for a visible pressure indicator at the PRV location.
Designed as an OEM-style replacement or new-installation pressure reducing valve for 3/4 inch NPT potable water supply systems in residential and light commercial applications.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code and applicable local codes. Shut off the main water supply and relieve system pressure before removing or installing the valve. Ensure flow direction matches the arrow or marking on the valve body. Use thread sealant rated for potable water on all NPT connections and verify gauge port integrity before restoring system pressure.
