- 9-1/8 inch lateral length
- Fits compatible Triton II TR100 sand filters manufactured after May 1985

- Exact Pentair part number 152202Z for reliable replacement identification
The Pentair 152202Z Sand Filter Lateral is a genuine OEM replacement used in select large Pentair and legacy PacFab sand filters. Pentair's current replacement-parts catalog identifies 152202Z as a 9-1/8 inch lateral for the Triton II TR100 and Triton TR100C families, while current replacement references also document use in Tagelus TA100 and TA100D filters.
Sand filter laterals sit at the bottom of the filter and allow filtered water to return through the underdrain assembly while helping keep the filter media inside the tank. A cracked or damaged lateral can allow sand to return to the pool. Replacing the correct lateral restores the intended internal distribution system without replacing the complete filter.
Best For
- Pentair Triton II TR100 filters manufactured after May 1985
- Pentair Triton TR100C commercial filters
- Pentair Triton TR100C-3 commercial filters
- Pentair / PacFab Tagelus TA100 and TA100D applications
- Replacing a cracked, split, or damaged 9-1/8 inch lateral
Why This Part Matters
The lateral assembly is part of the sand filter's underdrain system. Water passes through the sand bed and enters the lateral slots before returning through the filter plumbing. If a lateral breaks or its slots become damaged, filter sand can escape into the return line and enter the pool. Correct fit is important because Pentair uses different lateral lengths and styles across its sand-filter families.
Common Signs to Inspect the Laterals
- Filter sand repeatedly appears in the pool
- Sand returns from the pool's return fittings after filtration or backwashing
- A lateral is visibly cracked or broken during filter service
- The lateral does not seat correctly in the hub
- Your filter parts diagram specifies Pentair 152202Z

Compatibility & Fitment Notes
Pentair's current parts catalog lists 152202Z as the 9-1/8 inch lateral for Triton II TR100 filters, with eight required, and notes this application for filters manufactured after May 1985. Pentair also lists the part for TR100C and TR100C-3 commercial filters with eight required. Current replacement references document TA100 and TA100D fitment as well. Because Pentair uses multiple lateral lengths and designs, verify the filter model, manufacturing date when applicable, and the 9-1/8 inch length before ordering.
Installation & Service Notes
Turn off the pump and fully relieve filter pressure before opening the tank. Sand-filter lateral replacement normally requires removing enough filter media to access the hub and lateral assembly. Inspect the hub and the remaining laterals while the filter is open. Install the replacement lateral in the same orientation and connection style specified for the filter, then refill and restart the filter according to Pentair's current service instructions. Do not open or service a pressurized filter.
