Electrical Question

Bathroom extractor fan vent position.

Hi

I am getting my bathroom extractor fan replaced (which was not installed properly in the first place). The existing hole had no ducting and was half covered on the exterior by the the wooden board just behind the guttering.

Its a Victorian terrace house with no real sofit - tiles stick out by about an inch with guttering running flush against the exterior wall secured to the wooden board.

If a normal exterior grill was installed it would be right under the guttering - would this be safer to use an something like this to avoid any rain water getting in?

I assume this can be used externally.

Thanks

Hi dave

you shouldn't need to use that adapter at all as the ducting should slope down as it goes through your wall this allows air and water to leave through the vents but not find their way back in.

Our advice would be to install a new fan core cut thro the wall install a duct thro the cavity to a new fan grille on the outside wall, save messing about with the old grille in the soffit, which if the property is older amy start to create new problems with water ingress etc.
