Connecting toilet to cast pipe

[diycooper]

I am fitting a toilet in one of my rented properties I am doing up. The stack inner diameter is 3 1/2 inch cast which goes straight down into ground. I need to use a standard plastic swan neck pan connector to get toilet back but am unsure how to get it connected into stack without cementing.


I am reading the MKS7 might do ?

Does this fit directly into a cast stack ?

If so do I then need a piece of 4 inch plastic soil to go in the MKS7 then connect the swan pan connector to it or is it just a straight MKS7 then then the swan neck pan connector will fit into this ?

Thanks

Couple of ways you could do it.....

Trim an adjustable 3 1/2" extension piece, fit to the cast

then fit the 90 Deg rigid into that

These are McAlpine BTW, both adjustable length.

Will the swan neck fit right in the extension or do you still need to insert a tiny piece of 4 inch plastic pipe ?

Would the MkS3 to swan neck do as Wickes sell the MKS3 for delivery.

I have already purchased this one so just need the right connector to go in the 3 1/2 cast then to the swan neck ?

Sorry for all questions just confused.

Would this one fit the soil stack then the swan neck I have purchased go straight into that

I don't use multikwik stuff but looking at the dimensions then yes, that extension will fit the cast, if your cast is 3 1/2", then the pan connector will fit into that.

Thanks for prompt reply.

Am I right in saying the other end of the pipe not the the stack end is 4 inch to fit directly into my connector ?

Not sure cooper, it's not very specific on diameter and as I mentioned it's always McAlpine I use.

It is described as an extension for a multikwik connector though, so going by that I would consider that it means that it's an extension for the standard 110mm pan connector.
