Febco Clanging

My irrigation system includes a Febco 765 PVB. When the system is on, after about 10 minutes the Febco clangs repeatedly for a few seconds, making the sound of a machine gun. Any ideas? I can call my installer, but I'd like to have some knowledge first. Thanks! ?(

Make sure there are no partially-closed valves upstream of the system.
