Inline Fan leaking

That's really interesting, thanks for the info. I definitely think it's a design flaw with the seams. Why they don't have some sort of rubber gasket escapes me.
Do they mean put silicone on the outside of the casing?
A few people have suggested not opening the window but our ensuite is small, fully tiled & I think mould would start to grow everywhere if we didn't open it.
Our new fan is stronger (think it's 245 cubic metres) but hasn't made any difference.

Put silicone where you would assume gaskets would be - does that make sense?

I hear you about the mould - we have two bathrooms, and the ensuite is really big (converted bedroom), and we had mould forming on the ceiling despite running the damn extractor fan forever - the only way to solve this was to open the windows after the shower, which makes you wonder why you put them in in the first place.

I also do think that these quoted extraction rates are a bit like the advertised mpg you allegedly can get for a car, or the range for electric cars on one charge: theoretically possible, but in practice unachievable.

To be honest, I would be quite happy to have them removed, they are doing more damage than good, as our electrician initially only secured the ducting to the fan with cable tidies and put no insulation round the ducting - ha, that caused a few issues!

I also think that, certainly in my experience, electricians do this job reluctantly - they can wire everything up, but the "plumbing" side of things they have little interest in.

Another annoying thing is the person who installed the 1st inline fan made a 6 inch hole in bathroom ceiling and used a reducer to attach to 4 inch ducting so I'll need to get a plasterer in to fix the hole if we go back to an axial fan on the ceiling. Not just a straight swap over. Hope you manage to get yours sorted.

Ok, that is truly annoying - good luck with everything!
