PVC Pipe Sizes: A Guide To Sizes and Dimensions

Early in my plumbing career, I mistakenly ordered pipes based solely on nominal sizes, resulting in a project delay when the fittings didn’t match the actual pipe dimensions. This frustrating experience taught me the importance of understanding the precise relationship between nominal designations and actual measurements in PVC piping systems. PVC pipe sizes use nominal
