Also check the check valve on the city water inlet. They have a tendency to stick a little bit open, and if it isn't seated the right way, water will drip out of that.
To do this, turn the pump on and let it stay on. Go out to the city water inlet, remove the screen, and push on the valve (don't stand in front of it) and release it really quickly. Do this a couple times until it looks like the puddle inside the city water inlet doesn't get any bigger.
