Webstone h-10701w 3/8 in Brass Spring Check Valve

Product Description

The WEBSTONE h-10701w is a 3/8-inch brass in-line spring check valve designed for one-way flow control in plumbing systems. The valve uses a spring-actuated, soft-seated poppet mechanism to prevent backflow and maintain system pressure integrity. Built with a brass body and brass disc, the h-10701w is rated to 200 psi working pressure, making it suitable for demanding residential and light commercial plumbing installations. Its compact form factor and threaded end connections allow for straightforward integration into existing pipe runs without major rework. Licensed plumbers and pipefitters specify this valve where dependable backflow prevention is required in potable water and compatible fluid systems.

The h-10701w is intended for in-line plumbing applications in residential and light commercial settings. Its full-port, threaded connection style accommodates standard iron pipe fittings on both ends. The valve supports both vertical and horizontal installation orientations, offering flexibility in tight mechanical spaces and retrofit scenarios. It is part of the Webstone Series 107 product line and is manufactured to low-lead compliance standards, making it appropriate for potable water service where lead-free requirements apply under applicable plumbing codes.

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 any existing valve or fitting. Ensure pipe threads are clean and apply appropriate thread sealant or PTFE tape before making connections. Verify flow direction marking on the valve body is aligned with intended system flow direction before final tightening.
