90mm Soil Stack

[gfh123]

To solve an unpleasant backdraft I need to fit a wind cowl/cover to the top of a 90mm (3.5") diameter cast iron soil stack. I've searched everywhere but come up with a complete blank. Does anyone have any suggestions re sourcing one or obtaining an adaptor. Thanks.

Backdraught on a soil stack sounds improbable to me.

Any more details?

Won't fit it's 110mm OP needs 90mm.

@gfh123 any more details as per poles apart?

Might need a flex seal type connection if it is what you need
