Exclusive Solution for Running Water Control

The YoLink LeakStop is the only solution designed to automatically stop running water in home, office, or apartment toilets and sinks. Prevent water waste instantly and safeguard your property by stopping unnecessary water flow when leaks or excess usage are detected.

Offline Protection

No power or internet in the event of blackouts? No problem. If a leak is detected or daily limits for water usage, flush counts, or duration are exceeded, the LeakStop can automatically close the valve—even during power or internet outages—keeping your home protected. This automatic shutoff feature is enabled by default but can be customized as needed.

Smart white handheld fob from YoLink. Four buttons aligned in a column from top to bottom labeled 1,2,3, and 4 with colors green, red, yellow, and blue.
