Yesterday while fixing some faulty lights, customer asks if I can look at the en-suit extractor fan that stopped working quite a while ago...
The ceiling only has a vent grill, so poke my head in the loft and find one of these poxy little In-line fans screwed to a joist....

But then look up at where the duct goes.....

And you guessed correctly, Where the flexible duct dips down...
It is full of water!!

That poor fan never stood a cat in hells chance of extracting much air outside!

Who in their right mind thought that this bodge up was ever going to work successfully??

The cheap and nasty Screwfix type feeble extractor fan - replaced shed loads of these over the years

Even without water in the vent pipe it would never be able to work over that length of flexipipe

Our village hall, built 20 years ago by a big firm of builders, had the same carp ducting extracting from the toilets with the same result, but with the addition of a few holes nibbled by the mice in the loft.

It’s rare that you see these condensation traps.

Would a £200+VAT ventilation course help to address that problematic mess

The root cause is even worse. The way houses are built in the UK with cold lofts. Having built my new house with a warm loft and warm roof construction it is a revaluation in so many ways and fixes so many of the issues with a cold loft and cold roof construction.

A hydroponic loft then?

Swap it for a pump, maybe.

Just thought I'd add these couple of photos after a revisit earlier this week....

This is the water that came out of that flexi duct.. (the base of my yellow tub is approx 330mm)
Which does prove it was probably air-tight as its was able to keep in all the water as well!!!!!

I also found out that the original fan didn't have a timer..

Just basic feed wired direct off the nearest light..
with another quality workmanship cable joint!!!

Seen so many fans wired like that.
