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. When the tank water level falls to a predetermined level, a float assembly on the diverter valve acts through a poppet valve therein to terminate the jet and divert water flow through the diverter valve to refill the tank and bowl, thereby readying the toilet for another flush cycle.
