Surprise... Sprinkler System

In the garage, hidden in the corner, ever since we moved in, has been a Rain Bird control unit. I knew it was for a sprinkler system. I had seen the sprinkler heads here and there around the house. Today I turned it on and fired it up, not expecting much. To my surprise the entire system works perfectly. Six zones from the front yard by the street all the way to the back yard. The little sprinkler heads are incredibly strong. I had inadvertently put 25 lb stones over some of them and they easily lifted them up. Ah, water pressure.
