Does anyone have a solution on how I can fix the pipes from banging. Some of the baseboards are new and some are existing. The holes where the pipes are running through are 1 1/4 and the pipe is 3/4. The customer says the banging is occuring periodically, and I don't know what else to do, it is very difficult to see where it is coming from. I know it is the pipes hitting on the wood as they are heating. Does anyone have a good solution for fixing this or has had a similar situation. The baseboards are all on drywall with all the pipes running in between the studs. i tried shoving insulation in the holes, but it is still making noise.
