Find someone else to do the work. I had Dr. Sprinkler do a couple of hours of repairs on my sprinkler system. The kids they sent were gone about half the time ""getting parts"". The sprinklers were installed at an angle so they went too high on part of the sweep and sprayed straight into the grass on the rest of the sweep. The grass where they did their work was a mess. It looked like they had dug them up with a backhoe and put it back with a hand grenade. After $400+, I had to spend another hour or more finishing the job. Save yourself some grief and get someone else to fix your sprinklers
