Air lock

[gangeox]

Is there a way of installing a valve to the top of a rad to allow a hose to be fitted then flush out the radiator so as to remove any air lock?
the air bleed nipple thing is not very quick and with a big air lock will take ages. The rad is farthest from the boiler and is not getting hot at all no matter what i do.
Thanks in advance

Yes. It's not very pretty but you can remove the whole fitting which contains the bleed screw, replace it with a 1/2" BSP male threaded drain valve. That will have the nozzle to attach your hose to.
Make sure you use some PTFE around the thread to seal it properly.

Thanks for that it worked a treat.
