Patent number: 10352030Abstract: A toilet having a tank to receive water and a bowl connected with the tank. Water travels from the tank to the bowl to discharge waste in the bowl through a manifold connected to the bowl and into a drain line. The toilet has a jet trapway portion having a jet inlet with a nozzle connected with the tank. The nozzle directs water from the jet inlet to overcome an upward bend in the jet trapway portion until received by the manifold at an inlet below the upward bend. A waste trapway portion extends from the manifold opposite the jet trapway portion and connects with the drain line. Waste is discharged from the bowl through the manifold over a bend in the waste trapway portion by combining water flowing from the jet trapway portion into the manifold with waste flowing from the manifold into the waste trapway portion.Type: GrantFiled: March 7, 2016Date of Patent: July 16, 2019Assignee: FLUIDMASTER, INC.Inventor: Tuan Le
