Re: PVC diameter and cap question

	i also have SDR too.. but its 6" dia. ummm best way to tell if it is, 
is first, one end is "tapered" and you can fit another piece into it to make 
a snug fit.. the second way is that it is very thing( 1/8" MAX) i mean you 
can cut thru it using a punny little Dremmel Blade. 
goood luck,
