Product Overview

The Pentair 155007 sand filter lateral is an essential component of the internal underdrain system used in sand filtration systems for pools and spas. Multiple laterals attach to a central hub inside the filter tank and extend across the tank floor to distribute water evenly through the sand media.

During filtration cycles, water flows through the sand bed where debris and particles are captured. The lateral system then collects the filtered water and directs it back into the circulation plumbing. Properly functioning laterals are critical for maintaining balanced water distribution, preventing sand from returning to the pool, and ensuring efficient filter performance.
