Pentair Lid Assembly Complete | High-Capacity Automatic Feeders | R172385D

Description

The Pentair Lid Assembly Complete (R172385D) is the OEM replacement lid for the HC Series High Capacity Automatic Feeder, covering models HC-3315, HC-3330, and HC-3340.

The lid assembly seals the feeder’s chemical chamber, maintaining the controlled environment required for consistent chlorine or bromine dissolution. A compromised or damaged lid allows moisture intrusion and disrupts the measured feed rate — replacing it with the OEM-matched assembly restores proper feeder operation and protects the internal components from exposure.

Poolaroo Pro Tip

When replacing the lid assembly, inspect the lid O-ring and feeder body threads for wear, chemical deposits, or cracking before reinstalling. Chemical feeders operate under constant chemical exposure — if the O-ring shows any deterioration, replace it at the same time to ensure a proper seal and avoid a repeat service call.
