About This Item
OEM 2-Inch Pipe Assembly for Pentair SD40 & Cristal-Flo II Sand Filters
The Pentair Pipe Assembly (Part #152228) is the OEM replacement 2-inch internal pipe assembly for the Sand Dollar SD40 blow-molded sand filter and the Cristal-Flo II high-rate sand filter systems with a 19-inch tank.
This pipe assembly routes water flow through the filter tank to the laterals, maintaining proper distribution across the filter bed. A cracked, split, or warped standpipe disrupts internal flow patterns, reduces filtration efficiency, and can allow unfiltered water to bypass the media entirely — making timely replacement essential for system performance.

Pro Tip
Before ordering, confirm the pipe connection size stamped or molded on your existing assembly matches 2 inches and that your filter tank is the 19-inch model. While the filter is disassembled for this replacement, inspect the laterals and lateral manifold for wear or cracking — servicing them together eliminates the need to re-open the tank for closely related maintenance.
