Abstract
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 copper tubing 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 copper tubing 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 copper tubing 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 wh…
