ABSTRACT:
A plumbing fixture with a toilet bowl having a P-trap with means for inhibiting overflow from the toilet bowl when an obstruction exists in the waste outlet thereof, comprising: a tolet bowl having a flushing rim thereabout adapted to be coupled to a water supply pipe; an electrically controlled flushing valve for controlling the flow of water in the water supply pipe; a source of electricity for operating the flushing valve; a switch for controlling the flow of electricity to the flushing valve; a blow-out jet pipe coupled to the P-trap and adapted to be coupled to the water supply pipe; a hollow adapter having at least four openings thereinto wherein one opening is coupled to a water supply pipe, one opening is coupled to the blow-out jet pipe, and one opening is coupled to the flushing rim so that when water resides therein water also resides in the adapter via the opening coupled to the flushing rim, said adapter having a weir therein dividing the openings coupled to the water supply pipe and the blow-out jet pipe from the other openings therein; and an electrical probe mounted in the remaining opening in the adapter thereby disposing it below the top of said weir, the electrical probe being operably connected to a detection circuit, the detection circuit operating to prevent the electrical actuation of the flushing valve when water is in the flushing rim and in the adapter about the probe, and completes the circuit between the probe and electrical ground.
