Heating problem on floor standing boiler

[samtheplumber]

Hi guys,
I have a old floor standing Glow worm boiler. and when fired up heating gets upstairs ok from the 28mm pipes on the left hand side, but there are 2 x 22mm drops on the right to feed downstairs rads and is tee'd back into the boiler via a pump. Is the pump faulty? or is there a blockage after the 22mm tee? (hot above the tee not below)

Cheers guys

get a magnet to test the pipework if it sticks it is blocked. also could be pump.
