Abstract
A flush toilet includes a base and a bowl assembly defining a bowl. The bowl assembly is mounted to the base and defines a discharge opening at a lower end of the bowl. A waste ball valve assembly is mounted to the flush toilet for selectively opening and closing the discharge opening of the bowl assembly. A common sealing member operates to seal the bowl to the base and to wipe a ball of the waste ball valve assembly as the waste ball valve assembly is selectively opened and closed. The common sealing member has a generally horizontal portion for wiping the ball of the ball valve assembly and a compressible cylindrical portion upwardly extending from the generally horizontal portion. The cylindrical portion is compressed between the base and the bowl to define a seal therebetween.
