smelly? whats on the roof? I would get that sorted first.jduncan69 said:i have a ceiling mounted bathroom extractor fan which exits through the roof, is it possible to adapt so as to remove smelly back drafts when not in use?
thanks for any help
Andy (or anyone else), I have only seen these included in the fan housing and could do with putting one into my exiting duct work (just to stop drafts not smells). Can you give us a clue as to where you think these can be purchased ?andy said:jduncan69 said:breezer said:we had a fan with a non return "flaps" they close when fan not working, opened by pressure of fan, is that what you mean?
