Your water pump is probably just fine and not damaged. If your system is "pushing air and antifreeze out of the city water connection" then you have a bad/leaking backflow valve IN the city water connection fitting. Remove the screen washer from the inside of the fitting where the water hose screws into your city water fitting and you'll see a small "plunger like piece". That is the "backflow valve" it has O-rings that can dislodge, so be careful. GENTLY push that plunger in and try to recenter it. It's spring loaded, so should offer some slight resistance as you push. That might solve your problem, but if not, then you'll probably need to replace the city water inlet fitting.
If you don't have time to do a replacement right now, you can go to any hardware store and buy a "garden hose plug" to simply screw into the city water inlet. That will stop the water/antifreeze from bubbling out of the fitting until you do have time to replace it.
Here's some photos of what you'll find in the city water inlet fitting and one type of "garden hose plug"...
