  • Patent number: 9404247
    Abstract: A manual toilet flushing apparatus including an integral inlet fresh water valve assembly (IIFWVA) and a waste water discharge pump assembly (WWDPA) operably isolated from the IIFWVA is provided to preclude waste water from contaminating pressurized fresh water (PFW). The IIFWVA includes a pressurized fresh water inlet port to receive the PFW, an inlet valve body defining an inlet valve cavity (IVC), a second plunger in communication with a first plunger to actuate a check valve to direct a flow of the PFW into the IVC, and an outlet port. The PFW flows through the outlet port to a rim of a toilet bowl. The WWDPA includes a waste water inlet port to receive waste water, a discharge pump body, and a connecting rod in communication with a retractable handle to actuate a piston in backward and forward directions to suction and discharge the waste water through a discharge port.
