I recently repaired a leak in my water service lateral (1" PVC to 3/4" copper). The fitting I replaced was hard to reach without digging a LOT more hole. I got the copper-to-PVC adapter in well enough, but it was damned hard to get the PVC pipes into the glued-up slip joint because there wasn't a lot of flex available.
I thought afterwards that I could have put a series of right-angle bends in the PVC pipe which would afford a lot more flexibility during the repair. Is there a reason NOT to do this? Would make for stress in the pipe? Any hydraulic effects?
THanks a heap,
