When replacing my old Toro valves I noticed a very fine spray coming out of the Febco 715 Atmostpheric Vacuum Breaker.
It is a simple connection with [2] 3/4" female ends (top, side) to connect a brass pipe from home to poly that feeds a open/close valve to the manifold.

I'll get the FE765-075 - Febco® 3/4 inch PVB Assembly to replace it.
It looks easy to replace.
I am well above the 12 ".... and there doesn't seem to be any local rules (and think some of my neighbors have the same device).
It does appear the guy who installed this system years ago didn't do well.. He had too many zones, and buried the valves without a box
