Quick Plumbing question, air in heater pump.

SRRAE

Hi,

I removed a radiator to decorate and air has got in the central heating. The radiators are bled but the pump has air in it. I installed the pump about 10 years ago because the previous one failed and I remember having to bleed the air out of the pump, but I wasn't to sure how to do it. On the front of the pimp is a 10mm screw and I remember I had to either just loosen it or take it off and there's something behind it which allowed trapped air to escape.

Is this correct and can anyone advise if this is correct and how best to go about it?

Thanks

Should be a largish screwhead in the centre of the pump - unscrew this then gently press on the rotor inside using a screwdriver and this should bleed the pump. Might be some water,though.
