no pressure?

hello this is kem I understand you have no water inthe upstaires radiator but you need a bleeding key to bleed the radiators. You have to make sure your boiler is it gravity filling or not if you cheak your radiator you will see that may be air in it or you need to make sure you can fill it by filling loop this of coures depents what boiler you have can you cheak if the leak is from the pressure relive valve or it from ather pipe if it is leaking from the pressure relive valve you need to turne the red knob few time then fill it up if still letting water you need to replace it ( does your boiler over )
