A hollow detachable riser extension is mounted on the sump base and is of a size and shape, relative to the sump base, such that, when the riser extension is inverted, the riser extension can be received within the sump base for storage therein during transportation of the parts. The riser extension includes a cover and an annular step portion at the base thereof which fits over and around the upstanding annular portion of the sump base. The step portion is of a size and shape relative to the cover so as to enable receipt of the cover therein when the riser extension is inverted.
