WC connector to soil pipe

[Tweezer]

I have a 3.5 inch salt glaze soil stack which I need to connect to a new toilet, I’m struggling to find a connector to fit inside the existing pipe, any ideas

McAlpine drain connector.
If you really can’t get anything to fit then use a big fernco rubber connector with two jubilee clips built in - these are external so keep the full bore and they work very well.

I’ve never failed with a drain connector a decent application of silicon spray and either push it in or if it’s that tight a foot on it

Ian it a soil pipe, or floor drain connection? If it’s the latter, then you can use an extension b (mkea b) multikwik and bent pan connector.
