Sprinkler Leak and lawn bog/flood
Part of my lawn was a bit flooded last fall and boggy. I do not know how to figure out whether or not I have a broken sprinkler head or line. Heads seem to be ok when 'on'. There is no obvious out of control sprinkler head. Other than digging up the lawn looking for whatever pattern of piping may have been used in configuring the system, are there other tests I should consider first?
