dplawson Posted August 19, 2015 Report Posted August 19, 2015 LOL...especially when the kraft paper is exposed!
Tom Breslawski Posted August 19, 2015 Report Posted August 19, 2015 I've seen a lot of that lately. You'd think people would check before doing this kind of thing. "It's a good idea for energy efficiency!" Click to Enlarge 46.78 KB More insulation is NOT always better.
plummen Posted July 2, 2016 Report Posted July 2, 2016 So,is that a piece of sdr sewer pipe being used for a stack under the pvc or is it just a piece of really green dwv copper?[:-bigeyes
Jim Katen Posted July 2, 2016 Report Posted July 2, 2016 What do the letters SDR stand for? Marc In the trades around here, it just means "sewer pipe," though most people here call it "3034," after its ASTM designation. In a quick Google search, I was surprised to find that it actually means "Standard Dimensional Ratio" and refers to the ratio between the diameter of a pipe and its wall thickness - the lower the SDR number, the thicker the pipe wall. The thing in the picture does, indeed, look like sewer pipe.
plummen Posted July 3, 2016 Report Posted July 3, 2016 What do the letters SDR stand for? Marc Size Dimension Ratio,its normally sdr26 or sdr35. Basically its either 26 or 35 times the wall thickness of the pipe,We are only allowed to use it for sewer lines outside of a structure around here anyway.
