I have some 32mm pond hose (http://www.amazon.co.uk/1-25in-Corrugated-Black-Flexi-hose-metre/dp/B007V1ZE16) which I need (read: would like) to connect to a section of 110mm waste pipe. My Google foo must be weak, as I'm struggling to find a way to join the one to the other. I wonder if anyone with better pipe knowledge than myself can suggestion a way to forge a union between the two?
