How to choose

Alarm volume and alerts

Alarm volume is given in dB, and a higher figure means a louder on-site alarm: Flood Buzz gives 95 dB, GoveeLife and YoLink give 105 dB, and RUIKORING adjusts from 0 dB to 120 dB. Match the alert path to how you want to hear about a leak.

Range and placement

Range is the distance a sensor signal covers: GoveeLife reaches up to 1804 feet, YoLink reaches up to 2034 feet, and RUIKORING gives a maximum range of 328 feet. Place sensors where water collects first: under sinks, behind toilets, in basements, and beside washing machines. Flood Buzz fits behind toilet bases and inside cabinet corners at 1.75 x 1.5 x 1.5 inches, while RUIKORING suits kitchens, basements, and laundry rooms.

Battery life and packs

Battery life sets the replacement rhythm: GoveeLife and RUIKORING give 5 years, YoLink gives up to 5 years, and Flood Buzz gives up to 3 years. Pack size decides how many spots you cover at once: GoveeLife comes as a 3-pack, RUIKORING as a 5-pack, and YoLink and Flood Buzz as 6-packs. Moen installs on the main water line instead of sitting on the floor, so count it apart from the floor sensors.
