We've got 3 extractor fans in our house, all seemingly fitted by clowns who are somehow worse at DIY than I am - even though they would have been done by 'professionals'. New builds for you I guess! It's been on my list for a while, the en suite seems to get damp and we get bits of mold in the shower. For the meantime I've bought a little Bosh window vacuum thing for the water in the shower and we already use a squeegee but I'm going to replace the ceiling extractor with an inline direct to roof tile vent, just need to get someone in to do the roof as there's zero hope of me doing that. Currently the duct goes up into the loft, takes an immediate 90 degree turn and then goes around 12 foot to the soffit. I don't think it's working anywhere near well enough. I cleaned it out today and it was absolutely caked in dust.
I decided to tackle the one downstairs today, it's not been used since we moved in because it sounds like a 747 taking off. After removing the cover and getting the exact model number, then checking the manual, it has three settings via a jumper in a block, 1 being the lowest and the 3rd being Heathrow. I changed it to 2, still far too loud so settled on 1. Whilst doing this whatever is holding it to the ceiling gave way and it fell down about 2cm (from the small gap that was there before). Both other extractors are like this too.
I decided to take the thing out and have a proper look.
It's supposed to sit on the ceiling via these little L shaped clips which are 'spring activated'. Except they aren't; they're old, brittle and basically ****. The extractor works perfectly, so I'm going to just silicone/glue the thing on as the best I managed was to get it on with a 5mm gap at the front of it. Either that, or replace it because it's the cheapest model and has no timer and only a trickle speed, which is effectively the '1' setting that it's on. Not sure it's worth the expense though as there's just a toilet in there, sink, and washing machine and we've never had any damp issues in this room.
