La Pavoni Steam tap indent repair. 

Ideally it is better to have a curved big washer with same curvature of the boiler. This will repair the deep indent.

Pressure depends on the setting of the pstat (new models) or of the ball spring for old models. Heavy leak caused by this dent may also cause weak pressure.

Excellent job! Thank you very much. Can I ask you how can I set the ball spring for old models? I mean: there is some possible setting? thank's again@@rueljuachon4374
