A toilet tank with a sediment removal assembly comprises a flexible tube connected to the upper discharge spout of the intake standpipe in the toilet tank cavity, and a configured length of coppertubing connected to the flexible tube for water to flow therethrough when the float valve is open to flow water into the tank during a flushing operation. The coppertubing has a longitudinal section which extends downwardly and vertically from its connection to the flexible tube, an integrally joined first lateral or horizontal section curved or bent to lie on the bottom wall of the tank adjacent to the rear wall, and an integrally joined second lateral or horizontal section curved or bent to extend substantially normal to the first lateral section and lie on the bottom wall of the tank adjacent to the then facing end wall of the tank. The lateral sections of the coppertubing include small spaced apart apertures opening inwardly toward the center of the tank cavity, through which jets of water are emitted over the bottom wall of the tank as water flows through the flexible tube and copper tubing. The copper tubing terminates at an open free end adjacent the end wall of the tank along which it lies, such open free end facing the opposite side wall of the tank at its intersecting corner region where it meets the adjacent end wall. When water flow through the flexible tube and coppertubing it is spewed out in a stream directed toward the opposite side wall at the corner intersection. The impact of the water against the opposite side wall in that corner region forces the water to turn and begin to swirl in a circular whirlpool current or stream on the bottom wall of the tank. Such whirlpool current or stream, combined with the jets of water being emitted across the bottom wall of the tank from the small apertures of the lateral sections of the coppertubing, agitate the sediment accumulated at the bottom of the tank, raising the sediment into the whirling stream of water, and carrying the sediment with such whirling stream of water toward the centrally located drain in the bottom of the tank which is open during the flushing operation to carry water to the toilet bowl. Thus, during each flushing operation, sediment in the toilet tank is automatically flushed out of the tank into and through the toilet bowl, and on out the drain conduit leading ultimately to the sewer tile.
