you can induce air from a small compressor at low pressures and usually hear a squeal with cracks or tight breaks, larger breaks require more air but not great pressure.

remember you can compress air but not water, air can be both dangerous and destructive if not properly used

Flow Control...?

This is either a valve issue or a leak, right? If I turn the spray heads off at the head and my pump still runs, it would confirm a leak? I don't have any wet unusually green areas.

Thanks,
BL

ps: I've been fight with some voles (though not in that area).

Forgive me for suggesting this if it's too obvious, but I know I/staff have come across situations like this where the FC on the valve in question has been cranked down by someone in error. (never the homeowner of course

Anyways, I always find it's good to never assume and double check the FC just to be sure when one zone is acting funny and the rest are fine.

Other than that, I would go straight to turning the heads off and checking for flow.. Then start the dig!!

Good luck with it, let us know the cause!

Valve have flow control? Maybe one of the guys here used the 'bread method, to block a line so they could repair it!!
