To get antifreeze into the city fill let the pressure off the system by opening a faucet somewhere. Then pull the little filter screen from the city fill and press the spring loaded check valve in. You should get a squirt of water/antifreeze mix at first. If you don't think you have enough pure antifreeze coming out pressure up and let it off again. Press the check valve and it should shoot pure antifreeze. Stand to the side when you do it. Ask me why I know that.
