A slow leak under a sink or behind a washer can go unnoticed for weeks, and by the time water shows up on the floor the damage — and a renter’s deposit — is already at risk.
These small puck sensors sit where leaks start, sound a loud 100 dB alarm on the spot, and send alerts to a phone through the included WiFi gateway. There is no plumbing or tools involved, and nothing to uninstall when moving out.
There are limits to plan around. The gateway works on 2.4 GHz WiFi only, and phone alerts depend on the app, so a missed push notification on mobile data is a known complaint. Test the alerts after setup rather than assuming they will reach you, and note that the $43.99 price here is the brand site’s price, not the Amazon deal price seen earlier.
