American Granby lf5100-1 1 Inch Bronze Spring Check Valve

Product Description

The AMERICAN GRANBY lf5100-1 is a lead-free, poppet-style spring check valve built for water well system applications. The body is cast silicon bronze with a stainless steel spring and a Buna-N seal, delivering reliable one-directional flow control in demanding installations. Rated at 400 psi WOG, this valve handles the pressure requirements common in residential and light commercial well systems. Each unit ships with a spring, washer, and lock nut. The valve is manufactured in the U.S.A. and meets lead-free standards, making it suitable for potable water service. Licensed plumbers and well system contractors are the primary installers of this fitting.

The lf5100-1 is designed for water well system plumbing where a reliable check valve is needed to prevent backflow and maintain prime. The 1-inch female threaded connections on both ends allow straightforward integration into standard threaded pipe runs. It is appropriate for residential well pump installations and similar potable water distribution setups where a low-lead, high-pressure-rated check valve is required by code or specification.

Installation Notes

Installation of this check valve should be performed by a licensed plumber or qualified well system contractor in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the water system completely before removing any existing valve or fitting. Ensure thread engagement is adequate and use appropriate thread sealant rated for potable water. Verify flow direction markings on the valve body are aligned with the intended direction of flow before completing the connection.
