What do u do about pipe vibration?

Depends on what is causing the vibration. Is it water hammer, insufficient pipe supports, faulty pressure reducing valve, etc, etc? More info and we will see what we can come up with.

I am with MGD, we can answer unless you provide more info. When does it vibrate, what causes it. Does it happen when you shut off a valve or flush a toilet?

Describe the vibration. Loud knock? Pipes shaking? What? Do you have a PRV (pressure reducing valve) see image installed where the water enters your house? Is it the hot or cold water pipes? Please give us all the details that you cam. Back to you, Tom
