Resideo whldt1000/u Water Leak Detector Cable Sensor

Product Description

The RESIDEO whldt1000/u is a water leak detection unit designed for residential use by plumbers, HVAC technicians, and property maintenance professionals. It combines a standalone detector with a 5-foot patented sensing cable that can be routed along floors, around equipment bases, or behind appliances to cover a broad detection zone. Two AA batteries are included, making the unit ready for immediate deployment without external wiring. The detector measures 3.0625 inches wide by 3.0625 inches high by 1.25 inches deep and ships in a white finish. When moisture contacts the cable, the unit triggers an alert to notify occupants before water damage escalates.

This detector is suited for residential water management applications where spot detectors fall short. The sensing cable extends detection coverage well beyond the footprint of the unit itself, making it practical for installations near water heaters, sump pump basins, under kitchen or bathroom sinks, and behind dishwashers. It is commonly installed during appliance service calls or as a standalone add-on during plumbing or HVAC maintenance visits. No low-voltage wiring or smart-home integration is required for basic operation.

Compatibility

Designed for use with water heaters, sump pumps, under-sink installations, and behind dishwashers as stated by the manufacturer. Suitable as an OEM-style leak detection accessory for residential plumbing and HVAC applications.

Installation Notes

Place the detector flat on the floor or a level surface with the sensing cable arranged to cover the target leak zone. For water heater installations, use the included double-sided tape and mounting hardware to secure the unit to the water heater base. Shut off the water supply to any appliance being serviced before beginning work in the area. No licensed trade credentials are required for basic placement, but plumbing or HVAC technicians often install these units as part of broader service calls.
