Yeah, well i went to my LSF already. Explained my problem already to the guy working in this department. And he said I was the first one with this problem. He tought it might of been the pump. and when I realized it burned, i tought it would be it for sure! But not even!!!!!! So even my LSf dosn t know...... It just seems like in my overflow, there is a pocket of air on top and won't go away. so seems like it won t syphon properly. but the guy told me that you can t loose syphon on these things... So I don t know anymore!!!! It will be cheaper to just throw this crap in the garbage and buy another one then to ask someone to come and check it!
