Doug, try wholesale plumbing companies. The name of the one here that I finally found it at is Morrison Supply Company, but they aren't in Michigan. I went through about 8 local plumbing stores that could get it, asking who they would recommend trying. Finally got the one that stocks it. Don't ask for SD 2729. Even Morrison didn't know it by that. Ask for thin wall gravity feed PVC. I paid 1.86 per foot for the first 2 sections. The last 3 sections the guy gave me a break on...about half price 94.5 per foot. So they can deal if they will. Good luck. Its a hunt, but well worth it. Jim.
