Pentair 152226 SD80 / Cristal-Flo II 26″ Standpipe & Lateral Assembly
The Pentair 152226 is a complete internal standpipe and lateral hub assembly designed for use with Pentair Sand Dollar (SD80) and Sta-Rite Cristal-Flo II 26-inch sand filters. It replaces the internal piping network responsible for returning filtered water from the filter tank to the return line — crucial when the original standpipe or laterals are cracked, clogged, or malfunctioning.
Key Features
- OEM replacement standpipe assembly — ensures correct fit for SD80 and Cristal-Flo II 26″ tanks.
- Includes central standpipe, hub, and six twist-lock laterals for complete internal filtration plumbing.
- Restores filtration integrity and water flow when old piping is damaged or deteriorated.
- High-quality durable materials designed to resist pool chemicals and prolonged use.

When to Use / Replace
Replace the 152226 assembly when the filter shows signs of poor flow, short runs between backwashes, internal breakage, or when the original laterals or standpipe have cracked or become damaged — common after many years of use or a freeze / over-pressure event. Restoring the internal plumbing ensures proper circulation and filtration efficiency.
Installation Notes
- Drain and depressurize the filter tank before disassembly.
- Remove the old standpipe and laterals carefully, clean the tank interior.
- Install the new 152226 assembly — seat the hub and twist-lock laterals securely per manufacturer instructions.
- Reassemble the filter tank, refill with sand (if required) or water, and perform a backwash/rinse cycle to confirm proper flow and seal.
