Abstract: Apparatus and a process is provided for restricting that portion of the flow of water which is directed through a tube to refill the bowl of a toilet after a flush. Typically, the bowl refills before the toilet tank fills so that some water overflows the bowl and is wasted down the sewer. Accordingly, a conduit is connected to the discharge of the bowl refill tube. The conduit has a tapered bore which diminishes continuously from its inlet to its outlet. The diameter of the bore at the conduit's outlet does not permit sufficient water to discharge and refill the bowl after a flush. The conduit is formed of material which is readily cut. An objective bowl water is established. In a process of progressively trimming back the outlet of the conduit, an ever larger and larger diameter bore is exposed, increasing the amount of water discharged.

Abstract: A device and method for engaging the fill valve assembly in a water closet and maintaining the fill valve assembly in a closed condition regardless to the level of water in the flush tank of the water closet. The device includes two suspension elements that engage the walls of the flush tank on either side of the float lever portion of the fill valve assembly. A flexible element extends between the two suspension elements, wherein the flexible element passes under the float lever as extends from one suspension element to the other. As the flexible element is pulled taut, the flexible element abuts against the float lever and upwardly biases the float lever.

Abstract: A tank type toilet has a water saving, vacuum-assisted flushing system that incorporates a diverter valve disposed in the tank portion of the toilet. During the flushing of the toilet, pressurized water is discharged from a ballcock valve assembly in the tank and delivered to the diverter valve which creates from the received water a water jet that is used to create a vacuum area within the diverter valve. The vacuum area is communicated with an uppermost interior portion of the bowl trapway to facilitate a main flushing action in the bowl that requires less flushing water. At the same time, the water jet entrains tank water therein, through water inlet openings in the diverter valve body, and delivers the jet and entrained water to the rim flushing passage of the bowl to augment the vacuum-assisted main flushing action.
