DiversiTech Flood Prevention Switches offer straightforward installation, convenient maintenance, and exceptional reliability. When the water level rises in the auxiliary or main drain pipe due to a blockage in the air conditioning condensate drain, the switch effectively interrupts the system, preventing water overflow and safeguarding against potential damage to doors, walls, and ceilings. The core of the switch features a robust yet accurate magnetic reed switch, constructed from materials resistant to rust and sticking, ensuring consistent and smooth operation on every occasion.
