Waterway In-Line Cartridge Filter [50 Sq. Ft.] [2"] [w/Bypass] (502-5070)

The Waterway In-Line Cartridge Filter [50 Sq. Ft.] [2"] [w/Bypass] is built for targeted replacement work on compatible pool, spa, bath, or equipment systems where the right part number is important. This Waterway Plastics item is associated with DE Filters & Parts and is selected for DE filter maintenance when the existing part no longer performs as expected or when a system rebuild requires a correctly matched component. The listed configuration includes 50 Sq. Ft., 2", w/Bypass, making it easier to compare against the original part before ordering.

Part number 502-5070 should be matched against the existing component, owner’s manual, or equipment label before installation. This component is useful during filtration service when cracked housings, worn lids, missing internals, or aging filter assemblies reduce water clarity or make routine maintenance harder. Matching the square footage, access style, bypass configuration, cartridge size, or sand-filter body details helps keep filtration performance consistent. For best results, inspect the surrounding seals, unions, gaskets, screws, or mating surfaces during replacement, since related wear can affect performance even when the main component is new.

This description is written to help identify the product by brand, part number, category, and application while keeping the content specific enough for search engines and useful enough for shoppers comparing similar pool and spa parts.
