How does the geo Waterlock work?


Waterlock’s innovative technology reduces water losses at home by detecting standing water, excess humidity and freezing conditions. Unlike most systems on the market today, it not only detects leaks, but shuts off the mains water supply if necessary.

Combined with an intuitive, easy-to-use app, Waterlock’s early-leak detection gives homeowners peace of mind and control of their water whether they’re at home or away.
