The Pentair 522623Z External Low Flow Switch Kit is the genuine OEM flow switch for the IntelliChem® chemical controller, supplied with a 3 ft cable. It tells the IntelliChem whether water is actually moving through the system, so pH and ORP monitoring and chemical dosing only happen when there's proper flow — a critical safety interlock that prevents dosing into stagnant water.

How do I confirm this part fits my equipment?

Check the part number stamped on the component you are replacing, or find it on the parts schematic in your owner's manual. If the number differs or is unreadable, send us your equipment model and serial number and we will verify fitment before you order.
