Hello,


I just had a new irrigation system installed for my new lawn. When the system starts up in the morning I am getting a loud banging sound that repeats multiple times. When the system changes to the other zone it happens again.


When the system shuts off I do not get any banging of the pipes or a banging sound.


I would appreciate any advise you can give.


Thank you for your time.
Jason

Where's the sound the loused? Can you localize the noise by feel? Any more details? Back to you. Tom

If it is a new install, why not have the installer come back?
