@JasonH - some older controllers will have that terminal labeled as a Pump Start Relay, so that is why it may have been labeled as “Pump”. Unless the “pump” wire worked itself out of the Rachio terminal or the solenoid turned itself (maybe the on/off cycles), not sure how it was working before.
Well it’s working currently as far as I can tell. We will ride this ride as long as we can. If anything changes I will come back and update here.
Thanks so much for everyone’s help!!!

Have you checked the solenoid wires?
