Hi! I have learned a lot about irrigation systems in the past couple months, but can't seem to nail down my current issue. It began with leaking sprinkler heads in zone 7 (24 hours per day). I also noticed some erratic operation when the system was turned on. I replaced the control panel and that seemed to fix the erratic operation, but the zone still leaked. I had someone out and they replaced the valve, and that seemed to fix the problem. A few days later, I noticed that zone 6 now had leaking sprinkler heads. I changed out the sprinkler heads (not really expecting it to fix the problem). I then inspected the valve and replaced the diaphragm. Then I replaced the entire top section of the valve. Still leaking, so I replaced the valve entirely, and that fixed the leaking sprinkler heads. Guess what...couple days later, I am now noticing leaking sprinkler heads in zone 5. It seems like too much of a coincidence that each valve is failing this way. Could my problem be something else upstream of the valves?
Thanks!
Thanks!
