I know this is old post but only link I found to my problem.
I jumped green wire. Pump runs but only when I do that.
What does that mean? What needs to be replaced?
Also I left it running and found it does pump air but guessing leak somewhere.
What can I add to line that will escape leak hole and show itself without damaging the system?
