[QUOTE="NozSpark, post: 180787, member: 601"] Firstly you need to make sure that you opened any isolator valves back up that you might have shut while changing the pump, then check for any air bleed screws/valves and open them until water comes out... you could also have air trapped within the pump, so slacken off the big chrome screw on the back of the pump until all air is removed.. If you still have an airlock after doing that, come back and either I or someone else will talk you through pushing it out with a hose! [/QUOTE]
