ok so i made a pvc feeder this weekend. My feeder goes something like this.... 4ft straight (4") pipe>22.5 degree elbow>45 degree elbow>22.5 degree elbow> 2ft straight section. The feeder isnt exactly working out. The feed gets stuck at the 45 elbow. I was figuring the 2 22.5 elbows would make the turn a bit more easy but apparently not. any suggestions? do i go with 4 22.5 degree elbows?
