Product Overview

The Pentair 152290Z sand filter lateral is an essential component of the underdrain assembly inside several Pentair sand filter systems. Installed at the bottom of the filter tank, the lateral allows filtered water to flow back to the pool while evenly distributing incoming water through the sand bed during filtration and backwash cycles.

This lateral is designed for use with Pentair Tagelus models TA40, TA50, TA60, TA40D, TA50D, and TA60D as well as Sand Dollar SD40 and SD60 filters, and similar Triton II configurations. The precision-molded slots allow water to pass while retaining sand media, helping maintain efficient filtration and preventing sand from entering the pool plumbing system.
