Ok, here are the photos of the two solenoid boxes and the parkway box. The parkway box is the one I think has a Febco type double check assembly. http://s1159.photobucket.com/albums/p632/texasf/

Just today I found a second solenoid box in the front yard so now I have something else to work with. It's go...
My wife and I bought this house just over 8 months ago. The house was built in 1996. We required that the previous owner install a new controller which is a Rain Bird ESP-M. Due to the drought in Texas, we are under stage 3 watering restrictions so we can only run our system once every 2 weeks. About 6 weeks ago I turned on the system by starting each zone in order manually. Each zone was set to water about 6 or 7 minutes. A couple hours later I could hear the water running. I went out to check ...
