Hello,
In new construction, does code allow couplings in a short run of 3" horizontal drain pipe? Saw an approximately 4' long drain pipe today that had two couplings in it. There should not be a need for that unless the pipe was damaged. I did not think couplings were allowed (especially in such short of a run.).
