Pentair 178562 (24901-0003) Tank Bottom / Lower Body Assembly (Almond) for Select Pentair & Sta-Rite Filters

The Pentair 178562 is an OEM tank bottom (lower body / base) in an almond color used on select Pentair and Sta-Rite pool filter systems. This part replaces the lower half of the filter tank when the original is cracked, warped, leaking, or the clamp/O-ring sealing surface is damaged.

Common Compatibility (Verify by Filter Model & Parts Diagram)

  • Pentair Clean & Clear cartridge filters (select models, commonly referenced with 50 sq ft configurations)
  • Pentair Predator / Warrior cartridge filters (select models)
  • Pentair EasyClean D.E. filter systems: EC60 tank bottom listing

Filter families can share similar-looking tanks across multiple sizes and revisions. Confirm your exact filter model number and the tank-bottom part callout in your parts diagram before ordering.

Key Details

  • Part number: 178562
  • Part type: Tank bottom / lower tank shell / base assembly
  • Color: Almond
  • Function: Provides the lower tank structure and sealing surface for the tank O-ring and clamp band

What This Part Fixes

  • Water seepage or leaks from the lower tank shell
  • Cracks from UV aging, impacts, freeze damage, or stress around fittings/clamp areas
  • Warped sealing surface that prevents the tank O-ring from sealing correctly
  • Damage discovered during filter rebuilds or internal element replacement

Installation Notes

  • Turn off the pump and relieve all pressure at the air relief before opening the filter.
  • Transfer bulkheads/fittings as required and inspect for cracks or worn threads.
  • Replace the tank O-ring whenever the tank is split (recommended) and clean all sealing surfaces thoroughly.
  • Clamp/band hardware must be tightened evenly per the manufacturer procedure (avoid over-tightening).
  • After restart, check for slow seepage once the system reaches full operating pressure.

What’s Typically Not Included

  • Tank O-ring (commonly sold separately)
  • Internal elements/modules (cartridges or D.E. grids/modules)

Maintenance Tips

  • Keep the tank O-ring clean and lightly lubricated with pool-safe silicone lubricant to reduce pinching and leaks.
  • Never open the filter until pressure is fully relieved and the gauge reads zero.
  • If the filter sits in direct sun, provide shade when possible to help extend tank life.
  • Protect the equipment from freezing conditions—ice expansion can crack tank components and fittings.
