About This Item
The Pentair Tank Bottom (178731Z) is the OEM replacement lower tank shell for the Clean & Clear RP cartridge filter series and the SEP Separation Tank series (SEP 48, SEP 72, SEP 96, and SEP 144).
What It Does
The tank bottom forms the structural lower half of the filter or separation tank housing, containing the water under pressure during filtration. A cracked, warped, or leaking tank bottom compromises system pressure integrity and must be replaced to restore safe, effective operation. Match the part number stamped or molded on your existing tank bottom before ordering to confirm the correct fit.

Pro Tip
Before ordering, inspect the tank clamp ring and any associated O-rings or gaskets at the tank seam — these components are subject to the same stress as the tank body and are worth replacing at the same time to ensure a leak-free reassembly. Consult your equipment's installation manual for torque specifications when reassembling the tank halves.
