I have a 4 zone system controlled by a b-hyve. It will make this sound for 1-3 of the zones (sprinklers for lawn) but not on zone 4 (drip lines). If I run the zone manually turning the solenoid it will still make sound. If I turn on another water source like the hose the sound stops. I tried to test the ohms and they seem stable at 0.04 (not sure if I did this correctly).
