Pentair 178560 Tank Bottom Assembly – Almond (150/200 sq ft Cartridge Filters)

Part # 178560 — a genuine Pentair replacement bottom tank body designed for Clean & Clear® 150 sq ft and 200 sq ft cartridge filters, as well as select Predator models manufactured after November 1998. This almond-colored lower housing restores structural strength and proper sealing when the original tank bottom becomes cracked, warped, or unable to maintain pressure.

Key Features

Direct replacement for Pentair Clean & Clear 150 and 200 sq ft cartridge filter systems.
Durable molded tank body engineered to resist chemical exposure and outdoor conditions.
Almond finish matches the original filter appearance for seamless integration.
Designed to work with the existing tank top, clamp ring, cartridge, and plumbing connections.
Restores proper filtration performance by ensuring a stable and leak-free filter base.

Typical Applications

This tank bottom assembly is used when the lower half of your filter has cracked, begun leaking, lost structural rigidity, or can no longer maintain pressure. Ideal for residential in-ground pool filtration systems using Pentair Clean & Clear 150 or 200 sq ft models.

Installation & Compatibility Notes

Shut off the pump and relieve system pressure before beginning. Remove the clamp ring and lift off the tank top. Drain the tank completely, remove the cartridge, and disconnect any unions. Replace the damaged tank bottom with the new 178560 assembly, reinstall the cartridge and tank top, and secure the clamp ring. Reconnect plumbing, prime the pump, and inspect for any leaks during startup. Ensure your filter model is compatible with the post-1998 tank design.

Why Choose This Replacement?

Using the Pentair 178560 replacement ensures your filter system maintains its original performance, structural integrity, and safety. This OEM-quality component fits precisely and avoids the risks associated with using aftermarket or incorrect tank bodies.

Maintenance Tips

Inspect the tank body annually for early signs of stress, discoloration, or cracking.
Clean the clamp ring and O-ring contact areas during each filter service to maintain a proper seal.
Monitor operating pressure regularly—sudden drops may indicate air intrusion or leaks at the tank base.
Replace worn or flattened O-rings when servicing the filter to prevent future leaks.
