About This Item
Merch Note: Product go live pending AQS adding this to their Product API and PC fixing Pentair parts pricing.
The Pentair Pump to Filter Assembly (155711Z) is the OEM replacement connection assembly linking a Dynamo or OptiFlo pump to a Cristal-Flo II sand filter system with a 22-inch tank.
⚠️ IMPORTANT: VERIFY YOUR SYSTEM CONFIGURATION
This assembly is confirmed for Cristal-Flo II systems manufactured 2009 and beyond. If your Cristal-Flo II filter system predates 2009, verify the part number against your equipment's installation manual before ordering.
The pump-to-filter connection assembly provides the mechanical and hydraulic interface between the pump outlet and the filter tank inlet. A failed or degraded connection at this junction causes pressure loss, leaks at the pump-filter joint, and reduced filtration efficiency. Replacing this assembly with the OEM part restores the factory-engineered seal and flow path between your Dynamo or OptiFlo pump and the Cristal-Flo II 22-inch tank.

Pro Tip
Before ordering, confirm your Cristal-Flo II filter tank is the 22-inch model and that your pump is a Dynamo or OptiFlo — this assembly is specific to that pump-filter pairing. If your system predates 2009, cross-reference the part number stamped on the existing assembly against 155711Z to confirm an exact match.
