Hello Chaps, after sorting out my drainage problem for me I have another plumbing problem! My nephew has a blocked macerator in his house. From doing a bit of googling it looks like a Broysan. The motor seems to be making a noise but when flushed nothing actually happens. Is this something I can attempt or does he need an engineer? A new one is about £240 and looks pretty simple to swap. But if it can be cleaned or unblocked I’m willing to try that first.
