I was given an XP4 that had only been used once as a demonstration, but it had no pipework with it. Ever since I've had it it has been very noisy, kind of a buzzing/rattling sound - like it has air in it. What's the best way to prime it without the standard pipes, and get all the air out? I think that must be the problem, as occasionally if you shake it, bubbles come out. But I can never get it all out. At the moment I am priming it by starting the syphon by sucking the hose.

Any ideas?

several times I heard rattling the axon of the impeller was damaged or missing but that was too noisy..

I don't think using other piping should cause the filter itself to make noise. Air bubbles should not cause the noise you are hearing either. Check the impellar. Make sure it clean, in the correct postion or not damaged in any way.
