I have a rainbird Sprinkler system. One of the zones the sprinklers do not pop up. Someone said maybe the valve is stuck closed from the winter. How do you open and close the valve manually to loosen it back up. and where would this valve be located in the little green junction box near where the zone starts????
they dont really stick from the winter. i would say if the valve has a problem the diaphram needs replacing on the inside of it. ( all you have to do is find the same kind of valve and take the old parts out of the valve and replace them, the top, and the solenoid with the new valve's parts. they can be anywhere in your yard. ive even found the valve boxes buried under bushes. some installers don't put them in boxes, they just bury the valves. if you know where any of the green boxes are open the lids and see what's inside. sometimes more than one valve will be in a box. turn the solenoid on the valve. ( this will be the peice that the wire are connected to on the valve. dont turn the solenoid too much or it will come out. just a 1/4 to 1/2 a turn or so maybe a little more or less. and when you find the valve that turns on the zone 8 that is not working that is the valve for that section. you may even be able to hear the valve trying to come on when the timer shows it is running. if not, then check for power at the valve. if no power. there is a short, bad connection, or bad module in the timer. if power- replace just the solenoid first. if that doesnt work rebuild the valve. if you have no luck finding the box with zone 8 in it then try a few tips. get a screwdriver and poke around where some other valve boxes are. they may be close together. use a wire locator or hire a professional to locate the valve and show you how to repair it. to manually open and close the valve- open upthe solenoid like i said. or use the bleeder if the valve has one.
