Description

The Waterway 519-4320 cartridge manifold plug is a direct OEM replacement part used in Waterway Crystal Water inground cartridge filter systems. This is a model-specific internal filter component, not a universal substitute. When the original plug is worn, damaged, or missing, replacing it with the proper Waterway part helps keep the cartridge manifold assembly correct and the filter rebuild cleaner.

Pro Tip

When servicing the filter, inspect the pressure relief assembly and lid O-ring at the same time. Replacing worn companion parts during one teardown saves repeat labor later.
