I've decided to use 32mm solvent weld pipe with swept bends and rodding eyes. Why not 21.5mm? There don't seem to be swept bends and rodding eyes available. Vertical run indoors to reduce the chance of freezing. For the connection to the cast iron soil stack I'm going to try a standard strap-on boss. I'll see if I can tighten it up to fit the smaller size pipe or at least put some padding in so it tightens OK. Then silicone to make a seal.
