Is this product loud when running? If so is it uncomfortably loud? or just a small humming?

I have installed three of these pump kits here in Hawaii. The pump is silent, since it goes in the pond underwater. The filter is nice but their pumps are not reliable. You will need to get a good replacement pump from home depot or from Amazon when your's dies in a year. The water noise from a waterfall will depend on how much splash you have on your waterfall (if you have one ). I would not make the waterfall any higher than 2 feet above the pond's full water level. If the water just returns to the pond from having the hose near the water surface, keep the return hose above the water so that it will not siphon back to the filter if the power goes out or if a hose ever broke somehow. The filter tub can be very safely buried with the collar 2 inches above the ground level. Hide the filter with a fake rock available at home depot, ask for them at the store. This filter system is only for very small ponds, 8 feet by 5 feet by 2 feet deep at most if you want really clear water, the filter needs to be backwashed at least twice a week minimum with koi fish. Use Claritymax Plus bacteria/barley malt powder (available from Amazon.com) to prevent excess algae. Hope this helps, Marty Wisner

Very little noise, Pump is submersible and filter has small water flowing sound. Can't hear it at all next to my waterfall.

It's def louder than a portable generator. If you start it up and don't hear it, you better go check on it. Having said that tho, I don't mean to say that it is distractingly noisy, just that you're going to hear it running.

No I don't think it's overly loud. I use it alot and the hum doesn't bother me. In NYC I have more noise with the windows open. I am very happy with this model.

We run ours on low & it's in the far corner of the room, so in ours is very quiet. It depends on what speed you run it on & how far you are from it.

I think something is not right if it is 'extremely' loud. Mine was not silent but it was like a low hum.

i've never noticed a hum. The red LED is a bit distracting, but I just turn it away from my line of sight. Seems to work just fine overall.Note: I am not an audiophile and don't hear frequencies much above 10 kHz. Sometimes other people hear things that I don't. FYI.

Mine does not hum, I use it as an automatic transfer switch in the living room, it's been on 24 hrs a day for a month with zero noise. I would return it and try another one.

It is not loud at all. However, it does get a bit warm. I have it sitting on my desk and it's been running good without issues. I'd say to make sure there's ventilation wherever you put it.

It's not very loud at all, I was surprised how quiet/relaxing the pump is while running at a high speed. I wouldn't recommend running anything at full speed, there is no need for that if you have cats.

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 very quiet, just a slight hum. I don't even notice it. I've had mine for several weeks! Quite satisfied !

I don't think it's loud at all! It has a slight hum when the motor kicks on.

Not noisy at all, but ours is outdoors in a built in cabinet. In a house, I'm sure it would have a discernible hum, but not enough to call it noisy!

It makes a little noise but not too much. It is just a low hum in the background

A hum that you can hear is normal. If it is loud, something is wrong. If it is noisy without a load connected, I would replace it. Are you sure you have not overloaded it?

It is a low pitch hum. Usually mine is on low and I get used to it and don't really notice it. Higher speed is more noticeable, but still more a medium pitch, not high-pitched.

I am getting the same thing. It is a buzzing/loud humming noise. Anybody know if this is a defect or if something else can be creating this?
