A pump assembly includes a housing and first and second valves. The housing has a fluid inlet port and a fluid outlet port. The first and second valves are substantially identical valves both including a mounting portion, a valve seat and a valve body. The mounting portion has a first end and a second opposite end. The first and second ends are both selectively mountable to a conduit defining a fluid path. The valve seat is interconnected to the mounting portion. The valve body is interconnected to at least one of the mounting portion and the valve seat for movement relative to the valve seat between a seated position and a closed position. The valve body includes a first side and a second side and is operative to seal against back flow from the first side and open to positive pressures on the second side. The first valve is mounted to the fluid inlet port with the first end such that the first valve normally functions to only permit fluid to flow into the housing. The second valve is mounted to the fluid outlet port with the second end such that the second valve normally functions to only permit fluid to flow out of the housing.

A toilet system includes a toilet and a pump assembly. The toilet has a bowl and a base. The base has a hopper for receiving waste from the bowl. The pump assembly is operative for pumping a source of flush water to the bowl and for pumping the waste from the hopper. A first flexible conduit interconnects the pump assembly and the bowl. A second flexible conduit interconnects the pump assembly and the hopper. The pump assembly is flexibly interconnected to the toilet for independent positioning relative to the toilet.
