Abstract
Water is conserved by detecting unintended inflow of water into the tank of a flush toilet. A sensor acoustically and/or vibrationally coupled to the flush toilet detects sound and/or vibration generated due to turbulence in water flowing into the toilet tank. An electronic circuit analyzes the sensor output to detect cyclical water inflow not intended by a user. The electronic circuit generates an alert such as an audible and/or visual indication that the toilet is leaking.
