Al, on the 6" PVC, you won't find it at HD or Lowes. I've heard from some that a few Menards carry it. If you are interested in using it, you need to find a wholesale plumbing supply house. Ask a couple plumbers in your area where they buy their supplies. I found a couple places that could get it, and one that normally had it but was out, and one that had it in stock, but didn't know what it was called! Ask for thin wall gravity fed sewer and drain pipe, 6". The ATSM numbers didn't seem to make much sense to anyone I talked to. I bought 2 10' lengths at 1.86 per foot, then the last 3 they sold to me for almost half that! It was 10.11 each including tax (8.25%). McMaster Carr has the best price for the 6/6/6 wyes, and the 45 els. If you use any 4", again better priced there. I got 6/6/4 wyes at Lowes for just under 19.00 each. Go figure, they have some fittings, but no pipe! Maybe the same fittings fit on the green S&D pipe that they carry, never tried to fit it together. I got my 6" flex from Woodworker's Supply. Best price I found. Waiting on the 4" to come off back order. With a little use of a hair dryer, it fits on the 6" PVC nice and tight. And for those of you with MiniMax and maybe other, dust inlets that are metric...The 4 inch thin wall PVC is a tight tight fit over that, then you can plumb with the pipe and fittings! I didn't even feel that I needed to seal the joint, but I did silicone the edge anyway. I'm guessing the other units have the same outlet for DC hookup that my E16 has. Hope this helps!. Jim.
