Ok, the problem isnt that i am stupid. Or so i thought. Ill give you the set up and the problem last. Zone 4- Corner beds of front middle part Weather Matic controller- 1 1/2 Problem, zone wont go. Here is what i have done so far and why i am confused. I tried all the other zones, they are 100% ok. I FINALLY found this control box buried under some ground cover. Open her up and all looks ok. Different than i would have done it, but it is i think about 6 years old. Wires "look" ok. I have not tested for current as i dont see how this will tie into the problem. Read on. So zone wont fire off timer so i decide to do it manually. I flip it and it sounds BARELY open. No water comes out anywhere. I try other zones and realize very little water indeed is going through that zone. So i pop the top and clean everything. i open valve a little to make sure it wasnt clogged. Nada clog. I reassemble the valve and still nothing. Here is where i get REALLY irratated. So tinkering as i think i unwind the cylinoid. (the electric wire gadget, sorry i am not technically that great) I get about 9/10ths of the way up and BLAMO the zone starts up just as pretty as can be. Every head goes and all is good. So i crank it back down. BUZ KILL! Everytime i take it almost all the way off it works, but otherwise it dont. I even bought a new electric cylanoid today to see if i was just really dumb and that would fix it. I knew better, but i was stumped. This has been a week long torment. Please help me here. I know the owner (commercial guy) is wondering. He says today, "Well, you can only do the best you can do right?" I said "no, im saving that for the end of the job" I'm a part timer as far as irregation goes i know. Gotta learn somehow i guess right? Besides, there are a major shortage of guys here that want work. Believe it or not. What am i missing? Everything else is fine except something with or around the cylanoid. HELP!
