Shop trusted pool filter parts from brands like Hayward, Pentair, Zodiac Pool Systems, Waterway Plastics, Jandy, Val-Pak, Aladdin Equipment, Praher, Raypak, Custom Molded Products, Carvin, and Waterco.

Pool filter parts are highly model-specific, so matching the correct replacement is important. A lid, clamp, O-ring, lateral, manifold, valve key, gauge, or air relief assembly can look similar and still be wrong for your filter model. Before ordering, compare the manufacturer, filter model, part number, tank size, valve style, plumbing size, seal shape, and any markings on the existing part. If you are unsure which pool filter part fits your system, contact Aqua Terra Backyard with photos of the filter label, the old part, and any numbers printed on the tank or valve. We can help you narrow down the right replacement before you buy.
