Re: [TCML] Coil forms, any good?

Hi Adam, All,
All PVC Pressure pipe is thick-walled, but the reverse is, unfortunately,  
not true. I have a piece of 3" pipe right here marked, 
3" Silverline COEX Cellular Core PVC-DWV PIPE IPS SCH-40 [ASTM F-891-00  
NSF-dwv I/O] 12 
SL-M-818 ** NON-PRESSURE ** NC 12/15/02 17:26

Thick  walled PVC is pressure pipe, which means it's
NSF approved for transporting  drinking water. Thin
walled pvc is drain pipe, which "may" have less  QA/QC
than pressure pipe.
