Bled radiator air came out no water the bottom gets hot but then stops on the third floor the rest of the radiators in the house working fine so do you think it’s a blockage

    It’s almost certainly not a blockage, the system pressure is probably too low to raise the water to the full height of the third-floor radiators.
