I had a customer that I have done alot of landscaping for call and ask me to start up his irrigation system while I was there to plant another tree. How do I do this? Is there anything more than plugging in and programming the module? I plan on making sure all of the sprinkler heads are functioning properly. I was curious if there was something I am missing. I know irrigatation people charge for this service all of the time. I plan on charging him...not sure how much though.
