      Its kind of hard what to tell you but some of the problems like you say come from , if the pipes are run through studs are joist and the holes are too smallthe pipe expans and moves and rubs on the holes to make a noise. Also you could have a loose washer in a valve that controls the water and also on a PRV valve. Do you have city water are well. Let me know. Try to pinpoint the noise buy turnning on 1 fixture and see if the noise comes from one fix. are does it on all.
