A plumbing fixture system comprising a plumbing fixture bowl and a trapway fluidly coupled with the plumbing fixture bowl. The plumbing fixture system further comprises a Venturi device comprising an inlet and an outlet. The Venturi device forms an interior volume. The Venturi device further forming a channel from the inlet to the outlet. The interior volume is fluidly coupled to the channel. Liquid flow from the inlet to the outlet causes a first reduction in pressure in the interior volume. The plumbing fixture system further comprises a conduit extending from the interior volume of the Venturi device to the trapway. The first reduction in pressure in the interior volume of the Venturi device causes a second reduction in pressure in the trapway.

A minor water leak prevention apparatus for a water inlet valve, in which a float is mounted on a regulation bar and received in a water container. The water container is mounted on a siphon tube. The siphon tube is formed with an air aperture. A counterweight buoyance switch is mounted on the water container. The counterweight buoyance switch has a counterweight water compartment having a lower end forming a water drain hole. The counterweight water compartment has an upper end to which a closure pressing plate is mounted. The closure pressing plate is opposite to the air aperture. The counterweight buoyance switch controls opening/closing of the air aperture. This arrangement allows water ingress through a water inlet valve to be stopped when minor water leakage occurs in a water tank.

A plumbing fixture system includes a plumbing fixture bowl and a plumbing fixture tank coupled to the plumbing fixture bowl. The plumbing fixture tank is configured to house liquid. The plumbing fixture system further includes a siphon flush valve assembly disposed in the plumbing fixture tank and an electric actuator configured to induce, via the siphon flush valve assembly, a siphon flow of a portion of the liquid from the plumbing fixture tank into the plumbing fixture bowl.
