Hi,
I have fitted an extractor fan to my bathroom in a 3rd storey flat. The problem I have is that the grille that is fitted to the outside of the wall is just a fixed vent and does not have the flaps to stop wind blowing back through it and into the room when the fan is not running.
Due to the height of the building it is not practical to change the external grille. Is it possible to buy something that could be used inline with the ducting to only allow airflow one way?
Thanks,
Alan.
