it can be done in compression fittings,22mm to 15mm with a 3/4 olive in the 22mm end

you can use compression fittings available from diy stores or plumbers merchants however make sure it is 3/4" and not 22mm as you need a adapting olive for fitting 22mm fittings on to 3/4" pipe and it may be harder to find
