Whilst I've got the cistern off, is there a fast filling valve? This

Is there an incorrect restrictor fitted? The design of a torbeck is
such that it's almost an "open pipe" when open, capable of filling
very fast but will shut off with a bang...

There are two restrictors supplied with a new valve, a HP (lots of
fins IIRC) and and LP (not so many fins) but you can use a torbeck
without a restrictor if your supply is gravity from a tank on the
floor above say.
