Pentair Pipe Assembly SD80 2 in. | Sand Dollar SD80 / Cristal-Flo II Sand Filter | 152238

The Pentair Pipe Assembly (Part #152238) is the OEM replacement 2-inch standpipe assembly for the Sand Dollar SD80 and Cristal-Flo II sand filter systems.

The standpipe assembly forms the central internal flow path inside the filter tank, directing filtered water from the laterals at the base of the sand bed up through the tank and out to the return line. A cracked, warped, or improperly seated standpipe allows unfiltered water to bypass the sand media entirely, compromising water clarity and filtration effectiveness. Replacing this assembly with the correct OEM part restores proper internal flow routing and ensures a sealed fit within the filter tank and multiport valve connection.

Fits Into

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Pro Tip

Before ordering, confirm your filter tank size and pipe connection diameter. The SD80 uses a 2-inch standpipe — if your Sand Dollar or Cristal-Flo II tank is a different configuration, verify the correct pipe assembly part number in your filter's installation manual or against the part number marked on the existing standpipe before adding to cart.
