ABSTRACT:
A system for monitoring a plumbing system having a plurality of fixtures includes a sensor vibrationally coupled to the plumbing system and a processor. The sensor detects a vibration produced by the plumbing system, and generates a signal representative of the vibration. The processor receives the signal, compares the signal to a signal database that associates each of a plurality of stored signals with operation of one or more of the fixtures, and determines that the associated fixture or group of fixtures has been operated based on the comparison. The processor also stores a record of the operation of the associated fixture or group of fixtures.
