As a contractor, I would always recommend having a pro do it. There are alot of little things like adjustments that need to be done. Timing, opening the water supply slow, are a few more. For the hundred dollars or so it costs, it is well worth it. If a plant dies or a piece of grass dies, what does that cost. Leave it to the pros. Just my thought.
