Assuming you have removed your S trap WC and are replacincing it with a P trap wc, you will be using a 90 degree quick fit adapter. These are available with a boss on the top which could possibly take your waste pipe.
This one is a Mc Alpine.
you sir, are a star.
when can I get one from?
I presume I'll need an anti-syphon AAV on it to stop it sucking the water out of the U bend of the sink?
having said that, a taller than normal U bend as someone suggested could be used - after all, the flush will have finished before someone has finished washing their hands and topping the sink's trap up.
perhaps best to use an AAV tho
