I have a Rainbird ESP modular sprinkler system containing 11 zones. When I turn the setting to "auto" the sprinkler heads in zone 1 just seep water. Zone 2 works fine...but I have 5 other zones where the water just seeps out of the sprinkler heads. Oddly enough, if I manually select zone 1 and press the start the sprinkler heads pop up fine. Now, I'm forced to manually turn the dial to each zone to get the system to work. For example, I just went and turned the dial to zone 1, and pushed start and works like a champ. I will have to do this for the next 10 zones to water my HUGH lawn. Appreciate any help!
