I have plumbed a new sink into my downstairs toilet and I was going to use the old waste pipes that are already there, however, I needed to slightly adjust the angle. I have bought a push fit waste bend and the extra 32mm waste pipe I need, but the old waster pipe is about 2 mm bigger, what do I need to get to avoid me having to change all the waste pipes (it would mean a lot of work doing that!)
