I have a Rainbird automatic sprinkler system about 5 years old. We haven't used it for the past two years due to drought restrictions and it was working properly. After turning it back on and reprogramming, it now cycles twice when it comes on. I manually set it to come on when the yard needs it. It starts at 0430 but it runs through two cycles and then shuts off. It's not a big problem because I have adjusted the time so it gives me the deep soaking when I want it but I would like to have it work correctly. Any ideas?
