Ventilation not fitting

[billbeaumont]

Hi,

I spent the afternoon connecting up my bathroom ventilation system which will run using an inline fan in the loft. I am using 100mm insulated flexible ducting and all went well till I tried connecting this to the roof tile vent. The spigot on this measures 105mm outside diameter and 103mm inside diameter. I tried stretching the ducting over this but it isn't going to work.

Can anyone help me with this simple task before I attempt a bodge job this weekend - the answer is probably staring at me but I'm being a bit blind now!!

Cheers

Will

Fit it around a piece of 100mm soil pipe and it should then push fit into your duct
