One of the things I learned pretty quick is to test the sprinkler system before and after aeration, and make a note that you did on the invoice. Many times when I've called back customers in 6 months or a year for service, they will say something like " last time you broke a couple sprinklers, you should do it for free or at a discount or something" Of course they didn't call you the day after the service because it didn't happen. It give you a little back up.
