It accepts standard female NPT pipe connections and installs in vertical or horizontal orientations without restriction to flow. The full-flow design eliminates internal obstructions, maintaining system efficiency. A neoprene polyester reinforced flapper with a smooth-edge design and cast iron and noncorrosive metal backing ensures reliable sealing on each cycle. The valve is rated at 50 psi, equivalent to 115 feet of head, at 130 degrees F, making it suitable for demanding pump and drainage applications. Licensed plumbers and pump system installers are the primary trades working with this component.\u003c\/p\u003e\u003cp\u003eThis valve is suited for installation in sump pump discharge lines, sewage pump systems, and general water handling applications where backflow prevention is required. It is designed for installation below a basin cover and works across a range of system configurations. Available connection sizes in the Unicheck line include standard, 1-1\/4 inches, 1-1\/2 inches, 2 inches, and 3 inches female NPT, giving installers flexibility across multiple pipe sizes on a job site.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFull-flow internal design with no restrictions to system flow\u003c\/li\u003e\n\u003cli\u003eInstalls in vertical or horizontal orientation\u003c\/li\u003e\n\u003cli\u003eNeoprene polyester reinforced flapper with smooth-edge design and cast iron and noncorrosive metal backing\u003c\/li\u003e\n\u003cli\u003eCorrosion resistant powder coated epoxy finish for extended service life\u003c\/li\u003e\n\u003cli\u003eRated at 50 psi (115 feet of head) at 130 degrees F\u003c\/li\u003e\n\u003cli\u003eStainless steel bolts included\u003c\/li\u003e\n\u003cli\u003eSuitable for installation below basin cover\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 systems using 1-1\/2 inch female NPT threaded pipe connections in residential and light commercial pump discharge or backflow prevention 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 IPC.
