My domestic central heating , problems with a lot of air in sysytem, all upstair radiators cannot bleed, expansion tank is full. When attempt to bleed the radiators nothing coming out. :cry:
Are the bleed points on the radiators blocked ? put a sheet on the floor to protect carpet etc, and get an old cloth. Take the bleed nipple out of the radiator and insert a pin, beware if it was blocked you may get wet so you have to be quick.
It could be airlocked, or there could be a blockage in the cold supply to the central heating side of the system.
