Watts 9257 Pressure Reducing Valve 3/4 in Lead Free

Product Description

The WATTS 9257 is a lead-free pressure reducing valve designed to regulate incoming water pressure to a safe, consistent downstream level. Based on the LF25AUB-Z3 series designation, this valve is factory set at 50 psi and sized for 3/4-inch pipe connections. Pressure reducing valves of this type protect plumbing fixtures, water heaters, and appliances from excessive line pressure that can cause premature failure or leaks. Licensed plumbers and pipefitters install this valve on residential and light commercial potable water systems where inlet pressure exceeds recommended service levels.

This valve is suited for residential and light commercial potable water service lines where incoming municipal or well pressure must be reduced to protect downstream plumbing components. The 3/4-inch size is a common main service line size in residential construction. The lead-free construction meets requirements for use on drinking water systems in jurisdictions that enforce lead-free plumbing standards.

Key Features

• Factory preset at 50 psi for immediate installation without field adjustment
• Lead-free construction compliant with safe drinking water requirements
• 3/4-inch connection size fits standard residential main service lines
• LF25AUB-Z3 series design for reliable downstream pressure regulation
• Protects fixtures, appliances, and plumbing components from high inlet pressure

Compatibility

Designed as an OEM-style replacement or new-installation pressure reducing valve for 3/4-inch potable water service lines in residential and light commercial plumbing systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the main water supply and relieve system pressure before removing any existing valve or making connections. Install the valve in the correct flow direction as indicated by the arrow on the valve body. Verify downstream pressure with a gauge after startup to confirm proper operation at the preset 50 psi setting.
