I remember working as a plumber's helper during my university days. There was this "old school" plumber who started on cast iron DWV, then went through the Copper DWV, then to ABS DWV over his career (this was more than 25 years ago and he was 65 back then)...anyway, he always sanded his ABS fittings and pipe ends lightly before applying the yellow sovent cement. He said he did that to make sure nothing was on the pipe that would cause a leak. I have never seen this step mentioned anywhere. Was this plumber wasting his time? Is there any merit in sanding the joints before glueing? Is any harm done?
