Performed full system check. Repaired lateral line leak on station 8 in the backyard beds along fence that was causing pressure loss. Adjusted crooked popups on stations 7 & 8. Replaced 2 nozzles on station 7 to reduce spray on fence & shed. When performing system check, the valve for station 7 stuck on twice. The DCA had to be closed in order to shut off the zone both times. When the DCA was opened, the valve did not continue to stick. Sent estimate to replace the valve. Disconnected the station so that the system could be ran with the valve sticking.
