An interface unit for connecting an accumulation enclosure of a gravity feed conduit to a vacuum conduit comprising: means adapted to be placed adjacent to a surface level for defining a hollow chamber; an enclosure extension extending downwardly from said chamber defining means and having an upper end in the chamber and a lower end spaced below the chamber, the lower end of the enclosure extension adapted to be coupled to said accumulation enclosure in fluid communication therewith, the upper end of the enclosure extension being closed, whereby fluid pressure in the enclosure extension will increase as material is directed into the accumulation enclosure when the extension is coupled thereto; a vacuum conduit extension extending downwardly through the enclosure extension and having a lower open end near the lower end of the enclosure extension, the upper end of the vacuum conduit extension projecting outwardly from the enclosure extension; and means responsive to the fluid pressure in the enclosure extension for coupling the vacuum conduit extension with the vacuum conduit.
