Legend Valve 105-106 Inline Check Valve 1-1/4 in Fnpt Brass

Product Description

The LEGEND VALVE 105-106 is a brass inline check valve sized for 1-1/4 inch pipe with female NPT connections on both ends. Check valves allow flow in one direction and prevent backflow, protecting pumps, water heaters, and distribution lines from reverse pressure. This valve is constructed from brass and meets ANSI/ASME B1.20.1 and ANSI/ASME B16.18 standards. It is installed by licensed plumbers in residential and light commercial piping systems where backflow prevention is required without the need for a specialized backflow preventer assembly.

The 105-106 is suited for inline installation in potable water supply lines, hydronic heating systems, and general plumbing distribution where a 1-1/4 inch FNPT x FNPT connection is required. The brass body handles typical system pressures and temperatures found in residential and commercial plumbing. Its compact inline design fits standard pipe runs without requiring additional fittings or adapters at the connection points.

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 before removing or installing any check valve. Apply thread sealant or PTFE tape to the male threads mating to the FNPT connections and tighten to hand-tight plus the appropriate number of turns without over-torquing the brass body. Verify flow direction arrow orientation before completing installation.
