Top 3 Features to Look for When Buying Water Leak…

Top 3 Features to Look for When Buying Water Leak Detectors

  • Automatic Shut-Off

    If you want your home’s water to be stopped at the first sign of a leak, 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 even more costly repairs down the road.

  • 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.
