Drain alert device

Abstract

A drain alert device for detecting an overflow condition in a drainage system having a drain conduit, wherein wastewater is received through an inlet of the drain conduit, is provided, comprising an overflow conduit extending horizontally from the drain conduit below the inlet. The overflow conduit leads to an overflow detection device which includes a vessel having an internal volume sufficient to contain an amount of overflow wastewater. A buoyant member having an elongated, substantially vertical, overflow indicator resides within the vessel, and the overflow indicator is guided by a guide tube extending above the vessel. Thus, the overflow indicator reveals the extent of an overflow condition by protruding through the guide tube in response to the level of wastewater within the vessel. The vessel further includes a drain port having a threaded coupling capable of receiving a conventional flexible hose so that the appliance may be operated despite obstructions in the drain conduit. Optionally, the overflow conduit includes a device for partially impeding the flow of wastewater through the overflow conduit into the vessel to minimize false alerts due to splashing of wastewater during normal drainage.
