An apparatus for delivering sludge-type matter from a supply line has a manifold conduit rotatably coupled on one end to the supply line and adapted to receive matter flowing therefrom. A distributor plate includes a plurality of ports extending therethrough. A plurality of distributor conduits are each coupled on one end to a respective port on one side of the distributor plate to receive matter therefrom. A rotating plate is rotatably supported on the other side of the distributor plate and coupled to the other end of the manifold conduit. The rotating plate is adapted to rotate relative to the distributor plate to align the manifold conduit with a respective distributor conduit to direct the flow of matter therethrough. The rotating plate has a plurality of stop cams formed on the peripheral edge thereof, each corresponding in position to a respective distributor conduit. A catch member is biased against the peripheral edge of the rotating plate and, thus, is adapted to permit rotation of the rotating plate in one direction, but prevent rotation in the other direction upon abutting a respective stop cam. The manifold conduit is aligned with a respective distributor conduit upon the catch member abutting a respective stop cam.
