Since when have you stopped assuming. Every post you have ever answered assumed the most complicated process which is why your postings are dissertations and seldom address the question asked. If you do not believe this go back and read any simple questions and see your answer that can run to several pagess. I have replaced hundreds of cracked male PVC adapters. I have never replaced a schedule 80 nipple or the copper it is attached to. If you want to address velocity, then comment on the use of 1/2″ CPVC in lieu of 1/2″ copper, when the CPVC opening is about a third of the area due to the thicker wall.
