I have a small problemb regarding a poxy cast iorn soil stack which is not only inside but takes up a lot of room. I put a new suite in but the toilet was an old one .This was joined to the stack via its own right hand connector ie built into the pan. I had to buy a new toilet pan as the one i had to replace the old one was close coupled system and it is to awrkward to use flexi hoses and bends as the angles are to tight . But the cistern flush handele is to close to the soil stack to allow boxing in and would stop the handle from being used. I cant afford the expense of having a new plastic soil stack replaced as this would mean ripping half the new kitchen out aswell. Is it possible to remove just the part that is in the bathroom replacing it with a plastic one and have it on the outside .? This is very fustrating as my bathroom is so tiny can you help.
