Ok so I change the valve still had the same problem. Then I checked the water valve at the street. Plumber for got to turn it on full blast. ALL is good. Thanks everyone.
Looked for leaks but cant find them. Water is on the other zones work great. I just had a new hot water heater put in. Only one valve. everything looks normal. So here is my plan. I plan to pull all the heads about 10 and cap them. I want to turn the water on and i think that will expose my leak. quick question. how do you know if you have a faulty valve?
OK here it gos. My sprinklers were working fine. I turned them off because of a storm that came through. I turned them on a few days later and the front sprinklers turn on but it seems like there isnt enough pressure. I checked the valve it seems ok. I don't see any major puddles. Only around the sprinkler heads. I think that's because there isn't enough pressure to push them up all the way. So what do you guys think?
