Built from low-lead brass construction and rated for potable water service, it includes integrated taps for system monitoring and pressure testing without line interruption. The spring mechanism ensures positive shut-off when flow stops or reverses, making it suitable for residential and light commercial plumbing applications. Licensed plumbers and mechanical contractors install this valve where backflow prevention and serviceability are both required.\u003c\/p\u003e\u003cp\u003eThis check valve fits inline in 1-1\/4 inch FNPT-threaded pipe runs in residential and light commercial water supply systems. The monitoring taps allow gauges or test equipment to be connected directly at the valve body, supporting routine maintenance and code-required backflow testing. It is well suited for installation on booster pump discharge lines, water service entries, and domestic hot and cold supply headers where reverse flow protection is needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLow-lead brass construction rated for potable water service\u003c\/li\u003e\n\u003cli\u003eSpring-loaded mechanism provides positive backflow prevention without relying on system pressure alone\u003c\/li\u003e\n\u003cli\u003eIntegrated monitoring taps allow in-place pressure testing and gauge connections\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch FNPT connections for direct threaded installation into standard pipe runs\u003c\/li\u003e\n\u003cli\u003eSuitable for both residential and light commercial plumbing systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation check valve for 1-1\/4 inch FNPT-threaded potable water plumbing systems in residential and light commercial applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC).
