I have an upstairs toilet, which I have extended to fit a bath and
sink. The soil stack is on the outside wall and is cast iron, I need to
connect the pipes from the bath and sink to it.Can I use a 'strap boss'
to do this?

No Strap Bosses are only made to fit PVC Soils Stacks. You may be able
to use a 'screw on' type boss but I cannot remember wether they fit CI.

You have a bit of a problem there. The Cast Iron Soil Stack will be a
real ******* to drill. It might be easier to fit a section of PVC Pipe
at the top of the stack and boss into that.

Cheers.. I thought that my be the case!
I will replace the top of the soil stack, I can put the sink into that
easy enough, but the bath waste will be below where the WC goes into
the stack, making the bottom section a bit more awkward to replace! Was
hoping there might have been an easier solution!
