Jim, I've used both the SDR pipe and normal PVC up to sch 120. I then turned to using PVC Heat Duct pipe. It has thin walls and comes in diameters up to at least 24" which makes larger secondaries much lighter. Originally, I had some concerns about it being gray (possibly due to carbon in it), however, although I didn't specifically measure it, I did not see any noticeable difference in performance. Here's a link to one company that sells it: https://www.indelco.com/c-2352-pvc-gray-duct-pipe.aspx
Cool, and it's about 2/3 the price of drain pipe (20' is $250 for drain pipe) - this is about $150 for 20 feet.
Now to find a local supplier in the Los Angeles area.
