Dripping from bathroom extractor fan

[Cosmic]

Hello

Our bathroom is very small, no windows, so has an extractor fan to obviously get rid of steam etc. This works fine during the summer months. However, now we are in the midst of Winter I can only assume that condensation forms somewhere along the foil pipe that leads from the fan, up through the loft to the outside world because the fan drips water. This is particularly dodgy as the fan is connected to the light source, so we've had to unscrew the fan to keep the electrics out the way. This means we have a lovely dripping hole in the bathroom ceiling. Can anyone suggest a cure? Many thanks.

Unless you've had a problem with the electrics I don't see the point in disconnecting it, they are designed for these conditions. By doing this you have prevented the damp air from being removed.

It may not have been running long enough time to clear properly or the tubing is not insulated or not running downhill out. If it has to rise vertically then it will take a long time to clear. Wrap loft insulation around the pipes to help prevent condensation and run the fan for at least an hour, preferably more.

we have the same problem,its the condensation that accuminates in the pipe and then drips into the bath,no point in disconnecting power,i dont think there is a lot you or i can do about it.

Thanks for your replies. The reason we disconnected the fan from the ceiling (it's still connected electrically - it just hangs sideways) is because the water would drip through it and would occassionally ping on the electric connection that makes the fan work - in the middle of the night we would hear the fan whirring away, so we thought it best to disconnect it. The tubing does rise vertically but I'm not sure how well insulated it is so I'll have a look at that. Thanks again. Roll on some better weather!!

You could also offset the vertical pipe and fit a drain trap so that the condensation discharges at the bottom to outside.
