    (b) a flexible tubular arm flow connected to said hose connection means;

    (c) a valve flow-positioned near said hose connection means and between said hose connection means and said tubular arm;

    (d) said arm having an interior channel connected to said hose connection means;

    said arm having a plurality of spaced apertures passing through said arm so as to flow connect said channel with an exterior of said arm;

    said apertures being of a size to allow alternatively a trickle flow or a spray therethrough;

    said valve also flow positioned relatively near at least a portion of said apertures;

    (e) said valve being at least a two positional valve having a first position associated with a first flow orifice sized relatively small and a second position associated within a second flow orifice sized relatively large, such that when said valve is in said first position, said apparatus is adapted to produce said trickle flow from said apertures and when said valve is in said second position, said apparatus is adapted to produce said spray from said apertures; and
