Ferroli optimax he plus 31c expansion vessel

[Myquantum]

hi everyone, I have just joined, so apologies if this has been asked before.
pressure keeps dropping to zero. When at zero there is no pressure on the expansion vessel,which should be at 1 bar, it looks like the only way to replace this is to remove the boiler completely.
can I just tee into ch return and add an external vessel ? I presume that I will to blank off the existing vessel. (Boiler is about 4 years old).
thanks in advance for any advise. Dave
