Does the pump itself make much noise when submerged?

No, very little noise. At least nothing you can hear above the very nice fall of water. We have it in a 2' by 1.5' plastic flower pot in our front yard. I just hear the water.

The pump does not make much noise...it's quiet unless the water level is below the intake.P

Noisy is a difficult term to define. Not more noisier than other pumps like it. You can definitely hear pump running. Suggest you have some barrier (wall or floorboard) between you and the pump if you want a quiet environment. Noise resembles a humming sound but does get louder as pressure builds up.

Not really, but I don't use it inside a room so the open air somehow muffles the sound of the pump. There is a hum that I hear when it's running

it's not noisy at all I can barely hear it unless the water level in the tank is really low then you can hear the water fall, but the filter itself is quiet.

There are no odd noises, it does let a lot of water flow so if you have good water pressure and turn it on full force you will have a quite a flow

I find it to be very quiet except when the reservoir is running low, which is good because it alerts me to refill the reservoir. I have it sitting on a rubber mat and the noise is almost nothing.

Not that bad....if you have used pvc to pipe it out, find a piece of rubber to put between the pump and the pvc...that will help to lower the sound from vibrations a little....

Yes. It is an underwater pump that makes no noise. I've had it for the entire season and it worked great!

There is gentle hum- it's a slight motor sound mixed with a water evaporating sound- it's almost a whisper like the name lol. It's not bothersome to me. But it's not 100% silent.

I haven't experienced any noise after the pump stops and the check valve closes. It sounds like the valve is leaking a little bit and allowing water to drain back.

When I have been in our basement near our water heater, I have never heard the Grundfos pump unit make any noise. The part installed under the sink does not hum or make any type of noise whatsoever. We have had this unit for over a year, and we love it!

Mine does make some noise when the water circulates through the pipes but not excessive. It may have something to do with how much water pressure you have when the valve opens and closes.

I would say that the pump is a fairly quiet, muted sound. Doesn't run for long once you first inflate, just small adjustments here and there.

No, the pump gets just very loud, because it pumps mostly air. The thing is OK but nothing to write home about. If your floor is not 100% plane, the bowl runs over and everything gets wet.

Not at all, be careful not to let the air go in all of a sudden then it might sound (funny) But the pump itself doesn't make any noise.

standing 3 feet away from this pump you can only hear a very soft hum which is unavoidable,and my tank has water falling in it which completely covers the sound,definitely far from noisy,hope this helps...

Yes Amy, the unit makes a low humming sound with a slight vibration when in use. Make sure you use a little bit of liquid soap or jewelry cleaner in with the water.
