It is the genuine Hayward part, supplied as the complete underdrain rather than as individual laterals.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the laterals do\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAt the bottom of a sand filter sits a set of slotted arms feeding a central standpipe. Water works its way down through the media, passes through slots too fine for sand to follow, and leaves through the center pipe. When one of those arms cracks, the slot barrier is gone and sand goes out to the pool through the returns, usually appearing as a fine layer on the floor within a day or two of the filter running.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReplacing them\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is a full day job rather than a quick swap. The laterals sit under the entire sand bed, so the tank has to be emptied before the assembly can come out. Buy the sand at the same time, because old media that has been shovelled out and sat in a bucket is not worth returning to the filter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck your model\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis assembly is listed for the S144T.
