When our extractor was installed in the loft it wasnt installed correctly at all so was bouncing around. Pipe filling with water. Loft filling with moisture. I cant get to the top of the house easily to take the vent off and attach the pipe to the outside vent (which should have been done originally and wasnt). So when i noticed this it was a no brainer. Simple to fit and have had no issues since.
