How can i stop air getting into my central heating pump. Air seems to build up after a few weeks. Is there some sort of vent i can install

Sometimes the trapped air in the pump can be to do with the position of the pump.

Check which way your pump has been installed, The pump head should not be mounted in the vertical position ( the vent pointing vertically up or down)
