How to Choose a Smart Water Leak Detector

A leak detector can help you discover water where it shouldn't be. Some devices simply sound an alarm; others can send phone notifications or work with automatic water shutoff systems.

Decide what you need

A local alarm is useful when someone is usually home and can hear it. A connected sensor can send notifications when you're away. An automatic shutoff system can detect unusual water activity and stop the water supply, though installation requirements vary.

Where might sensors help?

Common locations are near water heaters, washing machines, dishwashers, refrigerators with water lines, and under sinks, plus other leak-prone areas. Don't place electronic equipment somewhere the manufacturer doesn't allow.

Check connectivity

Smart devices may require Wi-Fi, Bluetooth, a hub, subscription services, or a particular app. Understand that before buying.

Check alerts

Ask whether it makes an audible alarm, sends notifications, lets multiple people receive them, and what happens if Wi-Fi is down.
