SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

Since we have not been getting much rain, I decided to make sure my Rainbird EZ1 was working so I could water my grass. I have 6 stations, three valves located in the front yard and 3 in the back yard. After turning on the sprinkler system, stations 1, 2, and 3 (in one box )in the front yard all worked. I then went to check the back yard and station 4, 5, and 6 did not work. I turned the solonoids and I could not get them to come on. I then twisted the bleeder screws on them and they all came on. The major problem I have know is that the water will not turn off on station 5. The only way I can get it to turn off is to shut off the water source. Now I can't get any of the stations to turn on because 5 will not turn off.
How do I get 5 to manually shut off?
Do I need to replace a valve or a solonoid to get the three valve in the backyard to automatically turn on with the system or is there something else that I need to look at? How do I know which valve or soloind to replace with there being 3 of them in the same box.
Thank you in advance
