Ashland Water Group CV-100NL Brass Check Valve 1 in

Product Description

The ASHLAND WATER GROUP CV-100NL is a 1-inch brass check valve rated for 200 psi service. It delivers positive sealing action across both low- and high-pressure water supply applications. The lead-free brass construction meets current federal and state lead-free plumbing laws, making it code-compliant for potable water systems. Licensed plumbers and pipefitters install this valve where backflow prevention is required without the need for an active actuator or external power source. The spring- or swing-assisted check mechanism closes automatically when flow reverses, protecting pumps, water heaters, and distribution lines from backflow contamination.

This check valve is suited for residential and light commercial plumbing systems in 1-inch supply lines. Typical installations include domestic water service entries, booster pump discharge lines, water heater inlets, and irrigation supply connections. Its 200 psi pressure rating accommodates municipal supply pressures and standard booster pump outputs without derating. The compact brass body fits standard threaded pipe connections common in both new construction and retrofit plumbing work.

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 water supply and relieve system pressure completely before removing or installing any check valve. Verify flow-direction arrows on the valve body are oriented correctly before making final connections. Use appropriate thread sealant rated for potable water on all threaded joints.
