About This Item

Flow Switch for Pentair IntelliChem Chemical Controller

The Pentair External Flow Switch Kit (522623Z) is the replacement flow switch assembly for the Pentair IntelliChem chemical controller, supplied with a 3 ft cord for external installation.

What It Does

The flow switch signals the IntelliChem controller whether water is actively circulating through the system. When flow is detected, the controller is permitted to dose chemicals. When flow is absent, dosing is suspended — protecting the pool surface and equipment from concentrated chemical exposure.

Specifications

Description External Flow Switch Kit with 3 ft cord
Compatible Controller Pentair IntelliChem
Cord Length 3 ft
Quantity 1 Kit

Poolaroo Pro Tip

When replacing the flow switch, verify the switch is installed in the return line where steady, unidirectional flow is present — not near a tee or elbow that may create turbulent flow. A switch that triggers erratically due to poor placement can cause erratic dosing behavior from the IntelliChem. Consult your IntelliChem installation manual for the recommended installation location and pipe orientation before installing this kit.

For the DIY homeowner, Pentair represents the intersection of rugged durability and silicon valley-tier technology. They pioneered the Variable Speed Pump revolution with the IntelliFlo®, saving American pool owners millions in energy costs. Today, their ecosystem focuses heavily on automation, allowing you to control your pump, heater, lights, and chemistry from a single app. While they are a favorite among professional builders, their "EC" (E-Commerce) line of equipment allows homeowners to access pro-grade technology with valid warranties for DIY installation.
