Talking to a fellow plumber who told me that he usually doesn't install cleanouts. If the line doesn't have a c/o but is accessable, he'll drill a hole in the top of the pipe. Snake out the pipe, then put an expansion plug in the hole.
I really thought he was joking with me and he thought I was joking when I said he should install cleanouts. Anyone else do this crazy method? The poll is anynomous-whatever.
