Q: Will this standpipe fit in non-Pentair filters or different tank diameters?
A: No. The 152000 standpipe is specifically designed for Pentair’s SD70 / Cristal-Flo II 24-inch high rate sand filter and the Sand Dollar top mount configuration. Using it in other tank diameters or brands may result in improper fit or poor filtration. Q: How often should the standpipe be inspected or replaced?
A: Inspect annually during your seasonal or regular filter maintenance. Replace when cracks, distortion, or loss of structural integrity are visible—or when sand is passing through incorrectly or you notice uneven flow distribution.

Pentair Standpipe Assembly SD70 – Genuine OEM Part 152000
Replacement standpipe assembly for Pentair SD70 / Cristal-Flo II 24" sand filters. Ensures proper flow and reliable filtration.
Features
- Fits Pentair SD70 & Cristal-Flo II 24-inch high rate sand filters
- Genuine OEM part 152000 built to original Pentair specifications
- Durability against pressure, corrosion, and chemical exposure
- Lightweight (~40 oz) for easier handling during maintenance
- Simple drop-in installation: no alterations required
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.
