Correct Slope for 4 inch drain pipe
Posted by Dave K on December 12, 19100 at 11:46:50:
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?
