Pls help me with Eheim pump noise

[junxu95]

I bought a Eheim 1262 as a return pump for my 70G tank. I heard this pump is quiet, but there is still "bee" sound from my pump. I put the pump in the water. Did I miss something about using this pump, or I may just picked a bad one.

Thanks,
Ed.

Shake it around to loosen air bubbles..... Is it a rattling sound? Should be silent. Make sure it is fully primed.

turn it on/off a few times, just let the pump break in some more.

I just got a eheim 1262, and there is more noise from water movement than from the actual pump.
Amazingly quiet.

Make sure it isn't bumping up against the glass in the sump. I put rubber suction cup feet on mine to isolate it from the sump.
