The Pentair 520736 IntelliChlor Flow Switch Assembly is a genuine OEM safety component designed for IntelliChlor® salt chlorine generator systems. This flow switch assembly monitors water movement through the chlorinator cell and ensures that chlorine production only occurs when proper flow is detected—protecting the cell and heater system from dry operation and unsafe conditions.
With robust construction and precise activation characteristics, the 520736 flow switch assembly provides reliable performance and safety assurance for residential saltwater pool systems. It helps prevent damage to the salt cell, maintain consistent sanitization, and support trouble-free operation of your IntelliChlor system.

Frequently Asked Questions
Is the 520736 a genuine Pentair part?
Yes. The 520736 is a Pentair part supplied under that manufacturer part number. It is not a generic substitute.
How long does a salt cell last?
Salt cells typically last three to seven years. Life depends on run hours, water temperature and keeping salt within the manufacturer’s range. Low chlorine output at a correct salt reading usually means the plates are worn.
What salt level does the system need?
Most residential systems run between 3,000 and 3,500 ppm. Too little salt reduces output and stresses the cell; too much can trigger a fault and accelerate corrosion of nearby metal.
Can I use a salt system with any pool surface?
Salt systems work with most surfaces, but soft stone coping, untreated natural stone and some heater components are sensitive to salt. Confirm your heater has a cupro-nickel or compatible heat exchanger.
Why has chlorine output dropped?
The usual causes are a worn cell, scale on the plates, low salt, or cold water. Most systems reduce output below roughly 60F by design. Inspect the plates for white scale before replacing the cell.
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.
How quickly does this ship?
In-stock items ship from our US warehouse on business days. You will receive tracking by email once the order leaves the warehouse.
Can I return it if I ordered the wrong part?
Unopened, uninstalled items can be returned within 30 days. Equipment that has been installed or plumbed cannot be returned, so confirm fitment before installation.
Is this covered by a warranty?
Manufacturer warranty terms vary by brand and product. Warranty claims generally require proof of purchase and, on installed equipment, evidence of professional installation.
