Product Overview

The Pentair 24850-0102S bottom tank half kit serves as the structural base for Sta-Rite System 3 filtration systems. Installed as the lower section of the filter housing, this tank component supports the internal filtration cartridges or elements while providing the foundation for the pressurized filtration chamber.

The bottom tank half works together with the upper tank section, sealing O-ring, and clamp assembly to maintain a secure and leak-resistant filter housing. Built from durable materials designed for pool equipment environments, the assembly withstands pressure cycles, chemical exposure, and outdoor conditions. Replacing a damaged tank bottom helps restore structural integrity and ensures reliable filtration system performance.
