ABSTRACT:
An overflow control system for use with home appliances such as washing machines, incorporating conventional stand pipe which receives the outlet conduit from the appliance, the stand pipe being provided with an attachment having a displacement, conductivity or a pressure sensor installed for sensing the height of liquids in the stand pipe. This stand pipe may be vertically connected to the sewage line outlet found in a home and the signals from the sensors may be used to shut off the power to the appliance and to excite an alarm. Connected in parallel with the sensors may be a moisture sensor deployed under the appliance which again shuts the power off whenever the machine is inadvertently filled beyond its limits or when leakage occurs.
