My name is Raj and my Rachio3 suddenly stopped working yesterday. I had to raise some of my sprinkler heads. I released the pressure on the line by opening the relief value to drain the water in system (have a gravity assisted drain). After i was done raising the heads, i closed the value and started the system. None of the zones are working. I don’t hear the zone value opening. What could be the possible cause ? I checked my wiring and all of them are intact. Could releasing the pressure caused something ? Please help as i am lost.
I have a master value and zone valves.
