Product Overview

The Pentair 152226 standpipe assembly is an internal plumbing component used in Sand Dollar SD80 and Sta-Rite Cristal-Flo II 26-inch sand filters. Positioned inside the filter tank, the standpipe connects the lateral assembly at the bottom of the tank to the multiport valve at the top, allowing filtered water to flow back into the pool circulation system.

This assembly includes the central standpipe, lateral hub, and multiple laterals that form the underdrain system inside the sand filter. The laterals distribute incoming water evenly through the sand bed while collecting filtered water and channeling it through the standpipe. Replacing a damaged standpipe assembly restores proper water distribution, filtration efficiency, and reliable operation in compatible Pentair sand filter systems.
