When we bought our house, it already had a drip irrigation system installed. One of the anti-siphon valves had moss growing out of the vents, don't know what to call it (the non-valve side) and leaked when the system was off. I have replaced it twice and the problem persists! It's not the same as when the diaphragm is dirty and water bypasses it causing the emitters to stay on or leak. Why is this happening and what can I do about it?
