About This Item
The Pentair Pump to Filter Assembly (155710Z) is the OEM replacement connection assembly that links a Dynamo or OptiFlo pump to a 19-inch tank Sand Dollar SD40 or Cristal-Flo II filter system.
⚠️ IMPORTANT: SYSTEM VERSION NOTE
Compatibility with the Cristal-Flo II Filter System has been confirmed for systems manufactured 2009 and beyond. If your Cristal-Flo II system predates 2009, verify the part number against your equipment manual before ordering.
This assembly provides the dedicated plumbing connection between the pump outlet and the filter tank inlet, maintaining a sealed, flow-optimised path between the two units. A failed or cracked connection assembly can result in air ingestion, pressure loss, or water leakage at the pump-to-filter junction. Replacing it with the correct OEM assembly restores the factory-specified hydraulic connection between these components.

Pro Tip
Before ordering, confirm your pump model is either the Dynamo or OptiFlo — this assembly is not interchangeable with connection assemblies designed for other Pentair pump families. If your Cristal-Flo II system was manufactured before 2009, cross-check the part number stamped on your existing assembly against 155710Z before purchasing.
