Designed to help prevent flooding by automatically shutting off the well pump as part of a broader leak detection system; Leak Defender can use up to 6 hard-wired sensors to help catch leaks early, and some systems can also connect to alarm monitoring stations
230VAC bare lead model with 10-foot power cable; when planning the original purchase, flexible installation options can support up to 6 sensors with the Leak Defender system, and installation takes less than 30 minutes in a typical setup. The cable may retain a coil shape during installation, so lay it out properly for best sensor performance.
Connects in-line with a pressure switch for simple installation near pipes or a tap point connected to the well system; compatible accessories should be selected at the time of purchase rather than as a later retrofit, so buyers can compare features and price before finalizing related controls
Detects water at a preset level of 1/16 inch
Internal relay disconnects power to the well pump when water is detected
Manual reset pushbutton restores operation after an alarm; the user is unable to resume operation until the alarm is cleared and the reset is performed by pressing the pushbutton
Green LED indicates normal powered operation
Red LED indicates an alarm condition and pump shutdown in response to a failure
Uses an isolated low-voltage sensing circuit with no shock hazard at the probes
Stainless steel sensing probes
Waterproof epoxy-encapsulated sensor electronics are encapsulated to protect internal components, tested for reliable operation, and support long life
No control box required; this bare lead version is intended for a hardwired 230VAC power source rather than a plug connection, and we strongly recommend using a licensed electrician for installation where local code or wiring requirements apply; used in water treatment and well water equipment applications, including basements and similar spaces where temperatures can affect leak-risk awareness
The WaterPro Well Stop Sensor is a 230VAC water detection safety device from Aqua Science designed to help prevent catastrophic flooding in buildings with well systems by detecting water near the pressure tank area and automatically shutting off the well pump at its preset 1/16" detection level. It helps prevent damage from leaks by stopping the continuous flow of water once water is detected. That kind of early shutoff matters when water leaks waste a trillion gallons annually in the US. It is designed for installation near a well pressure tank, such as by well equipment in a basement, with the sensor positioned on the floor where a leak may collect, while also helping protect the house side of the system downstream of the pressure tank if water reaches that part of the plumbing.
This 10' bare lead unit is built for homeowners, property managers, contractors, and well system technicians who need reliable well pump flood protection in residential or light commercial well systems, and it connects in-line with a pressure switch and uses a built-in power relay to shut the pump off when a leak is detected, making it an effective leak sensor for well-system protection. That makes the WaterPro unit a practical leak-detection device for protecting property, equipment, water system performance, and overall home security against water damage, and it can also work with controls such as the Leak Defender, including connected leak-detection setups that can send smartphone alerts when water is detected and shut off water to the well pump.
When water touches the two probes, the sensor triggers shutdown immediately; water sensors typically detect water very quickly, and as a rapid-response benchmark the D-Link sensor detects water in less than one second, while the WaterPro unit responds by illuminating the red alarm LED and disconnecting power to the well pump. The green LED shows normal power status, the red LED shows a shutdown condition, the isolated probe circuit avoids shock hazard, and manual reset is required after an alarm. The details below explain operation, installation with a pressure switch, relay and LED behavior, safety features, compatibility with water well systems and Leak Defender controls, and how proper sensor placement supports reliable leak detection and water-damage prevention.
