Removal of Waterflow Switch

• To prevent accidental water damage, all control valves should be

shut tight and the system completely drained before waterflow

detectors are removed or replaced.

• Turn off electrical power to the detector, then disconnect wiring.

• Use a wrench on the flats of the bushing. Turn the switch

counterclockwise to disengage the pipe threads.

• Gently lift with your fingers, roll the vane so it will fit through

the hole while continuing to lift the waterflow detector.

• Lift detector clear of pipe.
