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,
