This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering. Poolaroo Pro Tip Sand filter laterals typically crack or split at the base over time, causing sand to pass into the pool return. Before ordering, pull the existing lateral and inspect it along its full length and at the hub connection point. If more than one lateral shows damage, replacing the full set at the same time avoids a repeat teardown of the filter tank in short order.
