The EcoPower sensor-operated Electronic Flush Valve utilizes a self-sufficient power source. Each time the toilet or bidet is flushed, water spins a small internal turbine, generating power that is then stored in a series of capacitors and used to power the flush valve’s sensor eye, microprocessor, and solenoid.
