Best Water Leak Detectors (2026): Moen, Phyn, TP-Link

Don't let busted pipes or an overflowing washing machine dampen your day. Water plays an essential role in our homes, but it can also wreak havoc. Burst pipes, leaky toilets, and misbehaving appliances can stop your day in its tracks. Water leak detectors help reduce the risk by alerting you to problems quickly so you can act to prevent severe damage. Around one in 60 insured homeowners file a claim related to water damage or freezing every year, according to the Insurance Information Institute, and the average cost of the property damage is about $15,000. The longer a leak goes undetected, the more damage it does, destroying furniture and decorations, spawning mold and fungi, and even threatening structural integrity. I've tested many smart leak detectors over the past few years, and these are my favorites. Insurers love them, so before you go shopping, it's worth checking with yours to see what they offer or recommend, and whether installing a leak sensor can reduce your premiums. Shaped like a drop of water, this versatile standalone device alerts you within seconds of detecting a leak and offers compelling extras like temperature tracking at a reasonably affordable price.
