Webstone THD-107XW Check Valve 1-1/4 Fip

Product Description

The WEBSTONE THD-107XW is a check valve designed to allow flow in one direction and prevent backflow in piping systems. Check valves like this are essential components in hydronic heating, domestic water, and plumbing distribution systems where reverse flow could cause equipment damage or system inefficiency. This valve features 1-1/4-inch female iron pipe (FIP) connections, making it compatible with standard threaded pipe installations. It is typically installed by licensed plumbers and mechanical contractors during new construction or retrofit work on residential and light commercial systems.

The THD-107XW is suited for applications where backflow prevention is required in threaded piping systems. Its 1-1/4-inch FIP connection size fits common pipe configurations found in hydronic heating loops, potable water distribution, and general plumbing service lines. The FIP threading allows direct connection to male-threaded pipe or fittings without additional adapters in standard installations.

Key Features

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Shut off the water supply and relieve system pressure before removing any existing valve or fitting. Ensure the valve is oriented in the correct flow direction as indicated by the directional arrow on the valve body. Use appropriate thread sealant or PTFE tape on all threaded connections before tightening.
