How do you change pool flow sensor?

To change a pool flow sensor, first, turn off the pool pump and disconnect the power supply to ensure safety. Locate the flow sensor, which is typically installed in the Plumbing near the pump or filter. Unscrew or unclip the old sensor from its housing, disconnect the wiring, and then install the new sensor by connecting the wiring and securing it into place. Finally, restore power and check for proper operation.
