We have cpvc also and have the same problem. I checked in our attic and there are (2) 1/2" pvc pipes running the length of the house. They are anchored with metal "nail in" brackets every other truss. If you found a cure for this problem would you please let me in on the secret? I read something about using a special type of plastic bracket to remedy this problem. If so what is the name of it? Thanks |
