I agree that thermal expansion is likely the problem, but it may be the PVC drain pipes, not the copper supply pipes. I have the same problem in my house. Plumbers seem to have a difficult time getting the thermal expansion tolerance correct on PVC pipe
, which expands significantly when warmed. Most of my neighbors have the problem to varying degrees.
