Allan, I've typically just had a weld-o-let tapped on the standpipe below the frost line, cold galvanized as necessary and then used a six inch piece of three or four inch plastic french drain around the ball drip, sloped slightly away from the pipe to inhibit silt infiltration (may or not be a problem--just using my Aristotelian brain instead of my observational one to solve a perceived problem) and then surrounding it with gravel. In a pinch I've used a two liter coke bottle with holes punched in one side. Less elegant but more McGyver.
