Applications & Compatibility
This tank bottom assembly fits Pentair pool filter models including Clean & Clear, Predator, Warrior and EasyClean systems where the original base has cracked, leaked or failed. Before purchasing, verify your filter's model, size and year of manufacture to ensure compatibility with part 178563.
Installation Instructions
- Shut off pump and relieve pressure in the filter system before servicing.
- Drain the filter tank if needed and remove cartridges or grids to access the base.
- Remove the old tank bottom assembly, clean and inspect sealing surfaces for damage.
- Position the new 178563 tank bottom, ensure proper alignment, install new hardware and media as required.
- Reassemble the filter tank, restore circulation and inspect for leaks or abnormal pressure when first operating.
Troubleshooting
- Leak at tank seam: Check that the assembly is seated properly, the gasket is intact, and bolts are torqued evenly.
- Excessive pressure drop: Verify cartridges/grids are installed correctly, media is clean and tank bottom is secure.
- Cracking or warping of base: Ensure the replacement is correct part 178563 and that the filter’s support is level and stable.
Maintenance Tip
Inspect the filter tank bottom annually for signs of wear, cracking or leaking—especially if the system has experienced freezing or heavy seasonal use. Replacing with the 178563 at first sign of damage helps protect the filter integrity, extends media life and ensures uninterrupted pool operation.
