Wow, There is sooo much knowledge out there! I'm a new member that has been watching the site closely for several months! The question that I have is what pipe does everyone pull? I see alot of you use PVC mains and Poly chutes. Do you use SDR21 or schedule 40? The local reps that I have say most people in my area pull 20' sticks (glued) SDR21 throughout the entire job. However more and more are switching to poly pipe. And what about drains? Does anyone use them? I have a Case Maxi and a Sullair Compressor.
