Abstract
Abstract An ultrasonic drain trap cleaning apparatus for use in a plumbing system. A drain trap is fitted with transducers which receive electrical signals from a signal generator to create vibrations within the trap thereby clearing clogging material. A flow sensor is optionally provided to check fluid flow. If fluid flow is inadequate, the sensor signals the generator to generate signals to the transducers, causing vibrations thereby. A central programmable generator may be provided to generate electrical signals to more than one trap having transducers, or a programmable generator may be provided at each trap.
