Product Overview
The Pentair 150085 extra long lateral is an essential component of sand filter underdrain assemblies used in many Pentair and Sta-Rite pool filtration systems. Positioned inside the bottom of the filter tank, the lateral collects filtered water and channels it into the return plumbing while ensuring even distribution of water through the sand media.
The extended length helps spread water evenly across the sand bed, which improves filtration efficiency and reduces channeling that can lead to cloudy water. The quarter-turn connection allows the lateral to lock securely into the filter manifold while making installation and replacement easier during routine filter maintenance.
