The shop
Eight people, four of them testers
Estacado does one kind of work: backflow assemblies, and the irrigation lines they protect. The testers carry their own gauges and keep their own licenses current. The rest of the crew repairs and installs, and the office keeps the lists, the reminders and the filing.
