Connecting Extractor to Soil Vent

[m4rky]

Hi, I want to connect my bathroom extractor to an unused soil vent ont the roof.

I have seen several posts on this forum regarding this and have not found quite what I am looking for.

I have a Vent-Axia Vent-A-Light which is 100mm.

The soil stack is 110mm.

So how to I connect the two together??
I haven't seen a product that will connect these two pipe sizes.

A link to a product would be great so i know what it is I am looking for.
Even better would be something Screwfix sells

problem you might have is rain ingress or condensation droping down into the extractor.

Use the flexi piping plus this

dextrous: Thanks for the link. I have the normal silver Duck Duct tape is the Power tape much better, it sounds as though it is more waterproof?

holty: Hopefully I won't get any rain ingress as I have a mushroom on the top on the soil pipe. As for condensation, what will be the cause of this? Will it be caused by the air being extracted?
