I got 2 fluval 404 had them for about 1yr now, they are both leaking on the side where there is the clip. I was told to clean the impellar and I did. this happend to me twice and the only solution I had was pound it with my fist as hard as I can, it worked the first time, but when it was time to clean it and plug it back in it leaked again. I was also told to put vasaline on it but I dont think that would work, any one else have a solution??

Vaseline = Rubber Gasket maintainence 101. Teflon Tape is great for stopping leaks too. But not as good as a shiney new gasket.
the gasket or o ring sonetimes when you place it down does not completely fit perfect, so make sure it is wet and fits flush with your cover before starting it up. hitting it might break it and they are good filters just hard to start up like ehiems.
Also to be safe i would have your return tubes close to the top of the tank so in an emergency all the water does not leak out hahaha it happened to me man and my chick almost left me when 75 gallons was in our bedroom. good luck bro, also tape works good for extra support.
