company that would love to come in and destroy my yard and charge me $$$
doing it. So before the backhoe arrives to rip down my fence and
destroy my sprinkler systems, any and all recommendations on what to
check/do are most appreciated.
Cheers,

Is there a line that might be too shallow so it is freezing and causing
temporary blockage?

Highly doubtful. It's been above freezing until the last day or so for
weeks.
