This product is an Intex-specified replacement valve (part number 10747), commonly known as a "hook valve." It is specifically designed for Intex 1500, 2500, and 4000 series sand filter pumps (filters) for above-ground pools and replaces defective original piston valves. It is an essential component for restoring the filter's multifunctional switching capabilities, including filtration, water recirculation, draining, circulation, and shut-off. Important information: Original part number: 10747. Compatible filter models: Specifically designed for Intex 1500, 2500, and 4000 series sand filter pumps (please check your specific filter model before purchasing). Valve type: Multifunctional combination piston valve. Turning the operating lever on top of the valve activates the internal piston to switch between different water channels, enabling various pool maintenance modes.
