DROP Leak Detectors provide critical data to the DROP water management system to help protect your home from water damage. DROP Leak Detectors sense water in the area and continuously monitor the temperature. This is especially useful in climates where freezing can occur. The leak detectors can be independently configured to automatically shut off the home water supply when the temperature falls below a user designated level or just provide notification of the condition. All DROP products are proudly made in the USA.

Note: All DROP products require the DROP Hub to function.

Automatic Leak Protection

The DROP Leak Detectors provide the ability to shut off water to the home automatically if a leak is detected, or if temperature drops below a certain point to avoid freezing pipes. This can save you thousands on undiscovered water leaks and resulting water damage.

This next-level home protection feature will immediately send you a notification of the event, and can even be fine-tuned via the settings.

    DROP Leak Detectors are great. I like the battery life and built-in temperature sensor.

    I have not had a water leak since I installed the detectors. However, I tested and confirmed that they work great.
