I was standing on the porch petting my dog and appreciating the cool Spring weather in Texas when out of nowhere, one of my sprinkler heads popped up and sprayed water for about 1 second and went back down :o It can't go down that fast if I was controlling it with the remote. Did other sprinkler heads on that station pop up too? I can't say for sure but I don't think so. No one else was home. The sprinkler remote was in the house. I live in the country with no neighbors so there are no neighborhood kids that could have done this. I'm on community well water. Pressure is good. I don't know if this has ever happened before but it's the first time I've seen it. Can anyone explain what might have caused it?

Thanks
