Help my fluval 404 is not working

[artemisblossom]

I have fluval 404 and it doesn't work (and no I can't take it back) I have replaced the impeller, the inpeller shaft, and the round thing (impeller cover maybe)? The plunger thing broke also and I ordered a new one. The thing is , it is not sucking in any water at all. I have put a makeshift plunger thing in there but it is still not sucking in any water. The hoses are not clogged or anything.Does anyone have any ideas what could be wrong with it? Would that little plunger thing cause it to do this? It wasn't working when I first tried it and I bought the other pieces then the plunger thing broke but it wasn't working before that either, it will take almost 2 weeks to get the plunger thing I ordered, but I hate to wait that long to find out something else is wrong with it. Right now I have put 2 small filters I had on my 20 gal tanks on this one (55 gal) but that is not going to work for long and being so close after christmas I can't afford to go buy a new fluval 405

Is it primed?

Try holding the intake hose up higher than the water level in the tank, and pouring water through it to flush out the air.

It sounds to me as well that it is not primed properly. Try filling it with water and then filling the hose with water too. Start it up and I reckon it should work fine.

Is it making any noise when it is turned on?

Thanks for your replies everyone, filling the hoses with water and then submersing them and turning on the fluval seemed to work , it has been running now a few hours with no problems
