The Craftsman 10000002673 Super Check In-Tank Check Valve is a one-way valve for in-tank plumbing, with a 1/2" compression connection on one end and a 1/2" male pipe thread on the other (1/2" COMP X 1/2" MPT). The 1/2" compression to 1/2" MPT configuration supports connection to standard fittings in residential or light commercial in-tank installations. The valve is identified by part number 10000002673 and branded as Craftsman "Super Check." It is designed to prevent backflow in the tank's supply line and to maintain proper operation of the in-tank system when a check valve is required.
