Consider yourself lucky. Hard plumbing from the city water connection prevents the hose from falling out and having 15 minutes of water on the ground.
There should be a winterizing bypass where you normally pump antifreeze into the system.
Disconnect the city water.
Put the antifreeze pickup tube into the jug of water with the correct amount of bleach added.
Run the pump in winterizing mode with AND FW fill mode.
That should pump sanitizing solution into the FW tank.
