Where to Put Smart Water Leak Sensors and How to Test the Alerts
Place leak sensors where water will reach the probes, then test local and remote alerts before relying on the setup.

Walk through the home and look for places where a small leak could go unnoticed. Check under sinks, near a water heater and around supply connections for appliances. Think about where water will travel on the floor or shelf, including slopes and raised edges.

Match the sensor design to the location
A spot sensor needs water to reach its contacts. A model with a sensing cable can cover a longer run or reach behind equipment if the manufacturer allows it. Keep the sensor accessible for battery replacement. Check Wi-Fi or hub signal from its actual location, especially under a metal appliance or inside a cabinet.
Decide who will receive the alert
Check whether the sensor sounds locally as well as sending a phone notification. The EPA WaterSense leak detection guide distinguishes spot detection from systems that monitor flow. If someone else needs to respond, make sure they receive the alert and know which location it identifies.
Run a controlled test
Follow the manufacturer’s test method and verify the local sound and phone notification. Give the device a specific name such as “under the kitchen sink.” Recheck after a router change or battery replacement. Keep the path to the manual shutoff accessible and report actual leaks to a qualified professional when needed.
