Description
The Pentair 178627 Center Core Bottom is the critical lower component of the core manifold in EasyClean EC series filter systems. Designed as a durable housing element, it aligns with the upper core top and connects to the tank bottom, preserving flow geometry inside the filter. Its robust molded body withstands exposure to pool chemicals and UV over many years. When your original bottom becomes cracked, warped, or leaks, this replacement restores the structural integrity of the manifold chamber, helping to preserve filtration efficiency and prevent water bypass.
Pro Tip
Whenever you replace the bottom core, also inspect the center bolt, O‑ring, and top core. Users often replace all core components as a set for performance consistency.

Installation Tips
Always shut off pump and relieve system pressure before opening the filter. Ensure the mating surfaces are clean and inspect O‑rings or seals for wear. Align carefully to avoid cross-threading the center bolt. Do not overtighten — tighten only to factory spec.
