The Leak Defender is a unique sensor based water leak detection system engineered for simplicity, with easy installation that takes about 30 minutes. It is designed to detect leaks near the well pressure tank, manifold or other nearby appliances and shut off the water by cutting off power to your well pump while sounding an 80-decibel audible alarm. Up to 6 hard-wired water sensors can be placed on the floor in the mechanical room or near indoor well system components for fast proactive response to potentially catastrophic leaks. When the leak is resolved and the area and sensor are dried, a simple button press on the sensor is all it takes to restore power to the well pump.
It comes with dual cable output connectors for multiple sensors and will accept up to ten sensors at a max distance of 600 feet. Leak Defender RS has input/output signal capability for the house and other alarm systems if needed. This system uses a relay inline with the power either to a pressure switch or constant pressure controller for water pressure regulation.
No external power source is required as it draws off of the power going through the pumping system between the pressure switch and the circuit breaker. Installation is easy on new well pump installations and retrofits and does not require any plumbing. It typically takes less than 30 minutes to install and can even be connected to your alarm system’s central monitoring station IF YOU Select the version of the system you want from the drop list in the product’s section that indicates “with Relay”. This option upgrades the control box at the factory to include the ALARM INPUT/OUTPUT RELAY CONNECTOR MODULE but you can buy it separately to add on later if you order it without the module initially.
