About This Item
The Pentair Pump to Filter Assembly (155709Z) is the OEM replacement connection assembly linking a Dynamo or OptiFlo pump to the 16-inch tank of the Cristal-Flo II Sand Filter System.
⚠️ IMPORTANT: SYSTEM VERSION — VERIFY BEFORE ORDERING
This assembly is confirmed for Cristal-Flo II systems manufactured 2009 and beyond. If your system predates 2009, verify the part number against your equipment manual or the original part before ordering.
This assembly provides the sealed hydraulic connection between the pump outlet and the filter tank inlet, allowing water to pass from the pump into the sand filter for filtration. A damaged or deteriorated connection assembly can result in air entrainment, pressure loss, or leakage at the pump-to-filter interface. Replacing this assembly restores the integrity of the flow path between the two components. Match the part number on your existing assembly to 155709Z before ordering.

Pro Tip
Before ordering, inspect the part number molded or stamped on your existing connection assembly and confirm it matches 155709Z. If your Cristal-Flo II system was installed prior to 2009, consult your equipment manual to confirm the correct assembly part number for your specific configuration, as earlier production runs may differ.
