In response to Re: Correct Slope for 4 inch drain pipe
: What is the correct slop for 4 inch drain pipe? I have read in some places that drain pipe should
: slope at 1/4 inch per foot but if the pipe is 3 inch or greater it should be 1/8 inch per foot. Should
: it be 1/4 inch or 1/8 inch or does it matter?

Dave,
Most plumbing codes call fro a minimum of 1/8" per ft. slope.
