Pentair IntelliChem Flow Switch with Magnet, 10 ft Cable | 754000440
The Pentair 754000440 is a replacement flow switch with magnet for the Pentair IntelliChem chemical controller flow cell. It detects sample water flow through the flow cell and helps prevent the controller from feeding chemicals when flow is insufficient, protecting your equipment and improving dosing safety.
Key Features
- Flow verification for IntelliChem: confirms sample water flow through the flow cell.
- Helps prevent unsafe chemical feeding: disables/blocks dosing when flow is not present (controller dependent).
- Includes magnet and 10 ft cable: common replacement configuration for IntelliChem installations.
- OEM replacement part: designed to fit the IntelliChem flow cell assembly where this part number is specified.
Compatibility
- Fits: Pentair IntelliChem chemical controller systems using the IntelliChem flow cell (where 754000440 is specified)
- Tip: Confirm your IntelliChem parts diagram and existing switch style (connector/cable length) before ordering.
Specifications
- Brand: Pentair
- Part Number: 754000440
- Part Type: Flow switch with magnet (flow cell sensor)
- Cable Length: 10 ft
- Quantity: Sold individually
Common Reasons to Replace
- Controller shows low/no flow even when the circulation system is running normally
- Chemical feed is being inhibited due to a failed or intermittent flow switch signal
- Physical damage, cracking, corrosion, or water intrusion at the switch/cable connection
- Flow cell service/repair where the switch or magnet is missing or worn
Installation Notes
- Turn off power to the controller and circulation equipment before servicing.
- Install the switch/magnet in the correct orientation and location specified for your IntelliChem flow cell.
- Route the 10 ft cable cleanly to the controller, avoiding sharp bends, heat sources, and pinch points.
- After installation, verify the controller recognizes flow and that dosing enables only when flow is present.
- If flow still reads incorrectly, inspect the flow cell for scale/debris and confirm the sample line is not restricted.

Maintenance Tips
- Keep the flow cell and sample line clean and free of scale—restriction is a common cause of low-flow errors.
- Inspect the cable and connector periodically for damage, especially in outdoor equipment pads.
- If you service the flow cell, confirm the magnet is present and positioned correctly before restarting chemical feed.
- Maintain balanced water chemistry to reduce scaling and extend the life of flow cell components and sensors.
