Waterway Supreme Pool Pump C-Clip (319-1540) is a replacement pump component for compatible pool, spa, or bath equipment repairs. It is used when the original part is worn, cracked, missing, distorted, or no longer sealing correctly. Because pump assemblies depend on close alignment between the housing, diffuser, basket, trap, seal plate, and related hardware, the exact part number and pump series should be confirmed before ordering.This Waterway Plastics part supports proper pump service by helping maintain flow path integrity, reduce leaks, and keep the pump assembly operating as designed. Even small pump components can affect priming, circulation, noise, or equipment protection if they no longer fit properly.During installation, inspect nearby seals, O-rings, unions, baskets, and wear surfaces so related maintenance items are not missed. A careful repair helps extend equipment life and avoids unnecessary replacement of larger pump assemblies. Replacement pump component for compatible equipment Verify part number, pump series, and fit before purchase Helps support flow, sealing, priming, or pump protection Useful for targeted repairs instead of replacing a full pump Inspect nearby gaskets and wear parts during service
