DIY first flow diverter (part 2 is done and available on youtube)

This is the parts list for the diverter. It does not show the 1/2 inch pipe, 1/2 inch threaded adapter, 55 gallon barrel, or the o ring that is used for the vent.  The inch and a half pipe that contains the table tennis ball must be schedule 20 , the inside diameter of schedule 40 pipe is too small for the ball to fit inside it. Part 2 of the video is done and posted on youtube.
