Very thorough and quick work. It took Dave several days to work me into the schedule (to be expected since he is a small, proprietor run business) but once he was here he was able to diagnose and cure our old system in about 1 hour. Many chipmunk-chewed holes in bed drip-lines were repaired, and a busted pipe was detected and repaired, a damaged rotor-head was replaced, the mist heads in the back lawn were replaced with more efficient and far reaching heads using the same openings, One spray head in the front was replaced to contain the water to the lawn, not the sidewalk. As for extending the backyard zone, Dave explained that the water pressure would not allow this, but came up with an alternative plan that would be less expensive. To be added next Fall.
