ABSTRACT:
A water level warning device for use in conjunction with a bathtub or a sink, for audibly warning a user when the water flowing into the bathtub or sink has reached a predetermined level. The warning device comprises a cylindrical tube containing a floating ball and having a plurality of circular openings extending fully therethrough for allowing water from the bathtub or sink to enter the tube. The top of the tube has a pressure-activated sensor and a speaker in communication with the sensor. The height of the tube may be telescopically adjusted by the user, thereby allowing the user to set the level of water required to activate the sensor. In use, the floating ball floats upon the upper surface of the water entering the tube, and activates the sensor when the level of water reaches the top of the tube. Upon selective activation of the sensor, the speaker emits an audible alarm.
