Thanks to you all. You’ve been incredibly informative and given me a lot to think about. I hadn’t realised that macerators were such troublesome things to have, but judging by the comments and suggestions, I will certainly heed your warnings and avoid having one if at all possible!
Perhaps I need to go back to the plumber with a few alternative solutions (thanks to yourselves) and come up with a better plan.
