Waterway Manifold for Water Filter

No, this specific manifold (part number 550-4300) is engineered exclusively for the Waterway Crystal Water Cartridge Filter. It will not fit other Waterway filter lines, so verify your filter model before purchasing.

You should consider replacing the manifold if you notice cracks in the plastic housing, warped components, or if the internal air relief assembly is no longer seating properly. These issues can lead to poor filtration performance or water bypassing the filter cartridges entirely.

This product is the manifold assembly itself. It typically does not include the air relief valve or pressure gauge, so you will need to transfer those components from your existing assembly or purchase them separately.

Replacing the manifold is a straightforward task for most pool owners. You will need to turn off the pump, relieve the pressure from the system, remove the filter tank lid, and swap the old manifold for the new one, ensuring the cartridges seat correctly into the new assembly.

The manifold acts as the central hub for water distribution within the filter tank. If it is damaged or misaligned, water can bypass the filter media, resulting in cloudy pool water and reduced filtration efficiency.
