An outside drain cock ??? do you mean PRV ?

DRain from a drain point, on or near the boiler, near the pump or on the radiator valve, can't find any ?

Remove one radiator connect a cutting of 15mm pipe to the valve using a nut and olive and insert the pipe into a hose pipe - open the rad valve an it'll drain.
