Product review (4 stars): Also bought a battery alarm water detector (works like a smoke detector but for water)
bought after the dishwasher and sink leaked twice causing our wood floor to buckle. its large so measure properly....and decide what to do if it fills with water.  Also bought a battery alarm water detector (works like a smoke detector but for water). Ended up the plumber and flooring guys just drilled holes in the subfloor to allow the water to drain to basement.  Using it now by the back door for the dogs pee pads.
