About This Item

The Pentair Kit-Flow Switch-iChlor Replacement (523100) is the OEM replacement flow switch kit for the iChlor series salt chlorine generators. Restore accurate flow detection to your iChlor system with the exact-fit part engineered for this generator line.

IMPORTANT: KIT QUANTITY
This listing is for a complete flow switch replacement kit. Confirm the contents of this kit match your replacement needs before ordering.

The flow switch signals the iChlor control unit when water is moving through the system. When this switch fails or becomes fouled, the generator will shut down chlorine production — even when the pump is running — resulting in no sanitizer output. Replacing the flow switch restores proper communication between your plumbing flow and the generator's control logic.

Poolaroo Pro Tip

Before replacing the flow switch, check that the existing switch body and port threads are free of scale buildup — calcium deposits around the switch port are a common cause of switch failure and can interfere with a new switch seating correctly. Use a stiff nylon brush to clear any buildup from the port before installation. Always shut down the pump and power to the iChlor unit before removing the switch.
