I need help with a heat exchange machine. It is a Casadio Dafne S1. The boiler was giving off a lot a of steam from the top of the boiler. Eventually so much that the boiler could not reach the desired temperature. After a bit of research I guessed it might be the anti-vac valve. I have taken a pic where the steam was coming from. It is covered with a rubber cap which has a tear in it from where the steam escapes. A pic of the inside shows that there is a pipe but not connected to anything. 1. Is this the anti-vac valve or something else? 2. I have removed the screw from the clip holding the rubber cap but still can't remove it. Need help with how to do this. 3. Should the pipe be connected to anything or is that the way it is meant to be? Thanks!
