Questions about ensuite installation in Caerphilly
Can an ensuite go anywhere?
It needs a route for waste water. Gravity drainage is best; where that is not possible, a macerator or pump can work. We check at the survey.
How noisy are macerators?
Modern units are quieter than older ones but still audible. We use them only where gravity drainage is not possible and fit them to reduce noise.

Yes, across the whole of Caerphilly, including Caerphilly, Gelligaer, Blackwood.
