Frequently Asked Questions (FAQs)
1. How does a water detector work?
Water sensors detect the presence of water and, when placed in locations where water should not be present, a leak. When Wi-Fi is enabled, the sensor can send out a notification to the homeowner through a smartphone app.
2. Do water leak detectors work?
Water leak alarms work great, but they will only help you to save your home if you're in your there when they go off. If you're out, you obviously won't hear the alarm, and if it's a big leak, a whole lot of damage could be done before you turn off the water and call the plumber.
