Top 3 Features to Look for When Buying Water Leak Detectors

  • Automatic Shut-Off

    When shopping for the best water sensors, look for water leak detectors with an automatic shut-off feature. As soon as the sensor detects water, it may sound an alarm, send you an alert, and stop your home’s water supply. While these water leak detectors can be more expensive, they can help you avoid costly repairs.

  • Temperature Monitoring

    Buying a water leak detector with temperature monitoring can warn you of freezing pipes. Frozen pipes can lead to bursting and repairs. Some water leak sensors with temperature monitoring can send an alert to your phone.

  • One last feature to look for when buying water leak detectors is access to a mobile app and alerts. Having an alarm that goes off while you’re home won’t help very much, but having an alarm you can check through your phone and receive alerts can keep you abreast of any leaks and temperature changes.

Factors to Consider When Buying Water Leak Detectors

  • Power Source

    Most water sensor detectors are battery-operated to easily be placed anywhere in the home without requiring professional wiring or wall outlets. If there’s ever a power outage, your water sensor detectors will continue to work. However, depending on the sensor, some must be wired and connected to your home’s water system for special features such as automatically shutting off your home’s main water source if a leak is detected. If you’re leaning towards a battery-powered water sensor detector, look for one with long battery life – some can last up to 10 years. You’ll also want to make sure your sensor has a low-battery warning to automatically alert you that it’s time to change the battery.

  • Water Detection

    Some water sensor detectors detect water leaks at less than ⅓ inch while others notify you of a leak as soon as water touches the sensor. Before you purchase a water detector make sure you understand how much water it takes to sound an alarm or send a mobile push notification. The best water leak detectors have adjustable sensitivity to give you the power of how much water should accumulate before sounding an alarm. Also, consider a sensor that floats just in case leaks quickly turn into floods. You’ll still be alerted when your sensor is submerged in water.
