Our building project is essentially a bungalow, we have two toilets and 4 sinks. The main waste pipe to the drain is already laid but I've never seen this done without a vertical soil-pipe for everything to join into, particularly sink wastes.
What are the names of the sort of parts I am after to join all the various wastes into the main drain (110mm IIRC) I can't picture how it should work
