Abstract
Rain gutter downspouts are fitted with either a one ball or two ball and socket joint. The joint is rigid. It bends up to 30° for a one ball joint or 60° for a two ball joint. Non-sealing joints are used to draw air downstream with the water. Further debris and clog clearing is provided with a venturi effect coupled with an acceleration along the concave sides of the balls toward the center of the gutter downspout pipes. Rotation of the ball along with tilt give the installer flexibility in keeping the wide side of the downspout pipe flush with the house as well as allowing zig zag patterns to avoid windows.
