Isn't the point of this forum to share advice and knowledge so that you're better informed when you do get somebody in? Whilst I appreciate the point you are making, it's not through lack of trying on my part. I've had multiple people in, and it's possible I've been unlucky. However, the reality is probably that every person has a different solution depending on their own experience. Just as on here, some have said accumulator, some have said blockage, some have said pipe size. They're all guesses based on experience, which I appreciate, as they have given me ideas to look into. There'll be some here who understand the science behind it, and it's those I'm asking to help to explain what I'm seeing.
One of the questions I asked at the beginning of this thread is quite a straightforward one. Would 28mm pipes be beneficial even though the megaflo inlets and outlets are 22mm. Hopefully amongst all the noise about secondary returns and how incompetent the plumbers I've had so far are, somebody might be kind enough to answer the questions I raised.
