The first paragraph
Leak detectors are essential for preventing water damage that can lead to costly repairs and mold. In 2026, a range of smart detectors offers features like temperature sensing, long-range connectivity, and integration with popular smart-home ecosystems. This guide reviews the best models and explains where to place them for maximum protection.
Overview of Leak Detector Technology
Leak detectors work by sensing moisture and, in some models, temperature changes. When a sensor detects water or a drop in temperature that could indicate a frozen pipe, it sends a notification to a paired smartphone app. The alerts allow homeowners to shut off the main water supply or take other remedial action before damage escalates.
Key benefits include:
- Immediate alerts regardless of location.
- Battery-powered units that last years.
- Compatibility with voice assistants like Alexa, Google Home, and Siri.
Common Placement Areas
- Under kitchen and bathroom sinks to catch leaking pipes.
- Crawlspaces where pipes may freeze.
- Behind washing machines or in laundry rooms.
- Behind toilets to detect overflow.
- Near water heaters and sump pumps.
- Behind dishwashers and refrigerators.
- Beside fountains or indoor water features.
- Behind fish tanks.
- Near AC or dehumidifiers that could overflow.
Many detectors offer an attached cable to reach tight spaces, such as under a toilet or below a water tank.
