We chose the Honeywell Lyric Wi-Fi Leak & Freeze Detector as our top pick because it offers easy setup and a smart sensor with Wi-Fi capabilities. It can sense changes in moisture, humidity, and temperature, so it can protect against mold and frozen pipes too.
Our runner-up, the Zircon Leak Alert is a simple detector with a no-fuss setup, loud alarm, and our favorite choice for traditional sensors. The LeakSMART detection kit includes a water shut-off mechanism but requires more money and time to set up.
Each of our picks are effective at guarding your home against water damage with clever alert systems and long battery lives.
