Abstract
A toilet having a seat section that includes a bowl with a bottom discharge opening. The toilet also includes a source of flush water for rinsing the bowl and removing waste through the discharge opening into a waste storage tank. A pump provides the flush water through a nozzle which directs the flush water into the bowl. A check valve is associated with discharge nozzle to prevent flush water from inadvertently leaking into the bowl. The check valve is capable of being used with either a manually actuated pump or a power assisted pump and reduces the force required by the pump to maintain the valve open than to initially open it.
