Had my unit fail after 6 years..seemed to start to leak from heat exchanger. I was able to replace the unit myself. I did not plump the setup just replaced same combi unit under way ..wondering if all the piping and valves are done correctly

Also anyway to increase water pressure? I'm on well

Is the filling valve necessary?

Also any explanation on how to bleed the radiator pls
