Abstract
An example vacuum-assisted toilet includes a toilet bowl including an outlet. The outlet of the toilet bowl is fluidly coupled to a first flush valve, for example, using a first pipe. The first flush valve is fluidly coupled to a second flush valve that is positioned downstream from the first flush valve. For example, the first flush valve may be fluidly coupled to the second flush valve using a second pipe. The second flush valve is fluidly coupled to a vacuum source. The vacuum source may include, for example, a holding tank having a vacuum pressure therein, a vacuum pump, or any other suitable vacuum source.
