Pentair 9-1/8" Lateral | Tagelus TA100 / Triton II Sand Filter | 152202

OEM Replacement Lateral for Pentair Sand Filters

The Pentair 152202 is the OEM replacement lateral for the Tagelus TA100 and TA100D sand filters and the Triton II Fiberglass sand filter. If your filter is channeling water around the sand bed or returning sand to the pool, a cracked or broken lateral is the most common cause — this is the correct replacement to restore proper filtration.

What It Does

The lateral sits at the base of the sand filter's underdrain hub assembly, drawing filtered water through its slotted surface while blocking sand from passing into the return line. A failed lateral allows sand to bypass the filter bed entirely, sending abrasive particles through your plumbing and back into the pool. Replacing a damaged lateral restores the filter's ability to trap debris and maintain clean, clear water.

Pro Tip

Sand filters typically use multiple laterals arranged around a central hub — replacing just one cracked lateral is a short-term fix. While the filter is open and the sand is removed, inspect every lateral for hairline cracks or broken tips. Replacing the full set at once prevents a return service call and is significantly less work than re-opening the filter a second time. Match the 9-1/8" length and 1-1/4" MPT connection against your existing laterals before ordering to confirm this is the correct size for your underdrain assembly.
