New Valve Vibration
I just switched out my old Irritol 2400T valve with a new one. Now when you turn on that zone is comes on vibrating and makes alot of noise. It will then quiet down but once it shuts off the whole thing vibrates and shakes again. I have tried turning on all the zones to release any air. Any suggestions on whats wrong or what I can do to correct this issue? Is this a bad valve?
