What is the difference between Schedule 40 and SDR 35?
SDR will bend with the shifting and settling. Having a higher flex tolerance means less breaks from the soil conditions. Schedule 40 is so rigid that in the event the ground shifts or settles this pipe has no give. It will simply snap or break from the pressure.
How do you measure plumbing pipes?
To find it, measure around the circumference of the pipe with flexible measuring tape. Divide the circumference by pi, or about 3.14159. For example, if the circumference is 12.57 inches (319 mm), you would divide by pi, and get an outside diameter of about 4 inches (100 mm).
