Adding extra pressure to the boiler.
Hello,
It's not the first time I have attached the filling loop to add more pressure to the boiler. But now when I try to add pressure water comes out from the bottom black cap.
I never had this happen before. I have tried to tighten this by hand but it already feels tight and I am not even sure it can be done like this.
What am I doing wrong?
