Extractor fan prob
Hi,
I live in a flat with an internal bathroom. It has an extractor fan that seems to be able to prevent the bathroom from steaming up very well, but somehow seems to suck in fumes from other bathrooms in the same block. Looking from outside we seem to have an outlet on the outside wall (about 3m from the bathroom) on each floor but still we are getting smoke fumes from other flat's bathrooms. We have an Xpelair extractor which has a flap behind the fan that only flaps 'outward' thus preventing air from coming in. We can only smell smoke coming in when the extractor is on - when it is off there is no problem. The extractor is sucking air out, but I assume not very efficiently. My question is, is it the extractor that needs replacing or do I need to put some sort of backdraft "preventor" behind it? My innitial though is that the extractor needs replacing since the problem only occurs when the extractor is on so maybe it is just not powerful enough, and the exhaust from other fans in the block is coming back in through mine. Any thoughts?! Any help appreciated. -- Ant |
