Does a central heating pump need bleeding?

Air locks often occur when air enters the central heating system and gets trapped in the pump. The trapped air will then reduce the rate at which water flows through the pump. Fortunately, if you are suffering from airlocks, all you need to do is bleed the central heating pump.
