Bathroom Extractor fan - How to keep water out?

I presume this would need to be fitted at the fan end and a waste pipe fed through to exit the external wall somewhere?

Fit it a few inches above the vent in the ceiling like in the photo, the condensate pipe will need to go outside somewhere yes, or if you have an internal stack it can go into that.

To put it simply, that shouldn't happen, however the good news is that it should be a simple fix!


Secondly, get into the loft and look at the pipe. I'd expect its a soft coil, if it is, try slightly raising it which will create a curve upwards which should stop any water travelling down the pipe

I wouldn't put a curve in it would act as water trap. Need to cure the cause.
Which will be something wrong with outer cover.

You removed my first point about the outer cover in your quote

1) Outer cover
2) Curve the pipe

That is, assuming this water is rain water as it sounds, and not condensation as others have suggested

Had a look at the pipe while fitting the new fan yesterday. It looks like it is just a solid vertical pipe. I assume it has some type of cap on the external end but it was dark and I couldn't see the top. would explain why I can't see a grill on the outside wall though.

Another assumption, but does this go out through a raised/vented tile in the roof then? Would look something like:

If so, then you either have a leak, or the most probable option as other have suggested - condensation.

I'm not entirely sure how you're going to fit it, if you have no roof access though. You're going to need to attach it to the vent which you might be able to do through the hole in the ceiling, but then you'll have to connect the condensation drip pipe to something, usually out through the wall.

Might have to measure up where the pipe would go outside, and drill from the outside in, feed the pipe through, hope it doesn't get stuck on anything and then connect it through the hole in the ceiling
