I have a potterton promax system HE plus boiler which is leaking everytime it's running. I have ID'd it coming from this plastic container at the end of a pipe I believe. As you can see, the fitting is not flush with its plastic setting on the right hand side anymore.
What is this piece, what needs replacing and is it something a novice can do themselves? At very least it's good just to know the name so I can call a plumber. Thanks
