Description

This standpipe assembly is the core flow path inside the filter, routing water from the top manifold through the sand bed and back out through the laterals. Over time, standpipes can crack, warp, or become blocked—reducing filtration efficiency and risking sand carryover. Using this Pentair OEM 152000 standpipe helps restore full filtration capacity and prevents uneven loading or channeling.

Pro Tip

When replacing the standpipe, take the opportunity to inspect laterals and the underdrain. Together with the standpipe, they ensure no bypass or leak paths. Consider installing a lateral assembly (e.g. SKU 150085) simultaneously.

Installation Tips

Always ensure pool pump is off and filter is depressurized before opening. Confirm filter model matches SD70 / Cristal-Flo II 24" tank for compatibility. Inspect o-rings/seals and replace if brittle or damaged.
