A pipe coupler couples the discharge pipe to the inlet pipe. The coupler has a middle portion having a middle internal diameter; a first end portion disposed at a first end of the middle portion and arranged to receive an end of the discharge pipe; and a second end portion disposed at a second end of the middle portion and arranged to receive an end of the inlet pipe. The middle internal diameter is adapted to provide a smooth transition between an internal diameter of the discharge pipe and an internal diameter of the inlet pipe.
