How loud is the pump. we're looking to use it for a school project and will be narrating while it's on. Thanks in advance.

It was a gift for my husband, and he doesn't have the best hearing, but when asked, said you could easily be heard over it.

The pump is very quiet. It works well. Can work on either one or two batteries. . a good buy.

I don't remember it being loud, just a little motorized noise. You should return it and have it replaced if it's loud! Good luck!:)

This pump is louder than some. But it shouldn't get louder when it's mounted, sound like it may be loose and vibrating. I can hear the pump with the engine off, but barely.

It is no louder than other filters. The main noises are the bubbles and the pump. If your pump is quiet the filter will be quiet. I keep mine in my bedroom and the noise does not bother me.

It uses a vibratory pump which emit some noise when running, but it should not be loud enough to scare anybody. It should be serviced or replaced.

We use it on our boat it's moderately loud when the motor is off, but our boat has a 250 on it and it gets hard to hear when it's running

the pump noise varies on surface and what diameter hose you have on it as that seems to conduct noise also (pump is louder with bigger tubbing I have noticed. I personally have is outside under a bucket so its pretty quiet in that case :) I know several people that could sleep through it, I could not, and I would think it would be too loud for a bedroom, this is a great pump but its definitely better a ways away from sleeping areas.

Not so fast people. *Most* of the time this unit is pretty quiet, only producing a very low steady hum. However, it *can* get annoyingly loud (3-4 times its normal volume) where it's sort of vibrating the plastic pieces of itself together. Topping off the water level sometimes helps a little, but most of the time it makes no difference. (It does the same thing right after a fresh cleaning too, so it's not an issue with debris.) When this happens, you can tap it / nudge it / smack it and the vibrating noise will cease - USUALLY. But sometimes it won't. There have been times where I wanted to smash it to bits with a hammer to make the noise stop. The only thing I've found that you can do to quiet it down is to completely open it up like you're cleaning it and pop the pump assembly loose and reseat it. It helps to barely press the pump down onto its suction cups, which is now what I do when I clean it. Before, I used to press the pump down firmly, which seemed logical but only increases the chance the unit will vibrate loudly. It seems like they ought to have put rubber seals between the plastic pieces where they meet or at least on the little studs the pump sits between or something, although I'm sure that would've increased the cost. Oh, I have the unit sitting on a thick, soft, rubber mat too. It's not sitting directly on a hard surface that would exacerbate any vibration noise.

At least yours still makes noises. That said, I had a similar experience with the HAAN I had. Upon start-up there are loud clicking noises that get quieter as the pump primes with water. The unit I purchased stopped working after the third use.

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

It's as quiet as this type of air pump gets. Not to say there isn't a little hum, but it's not obnoxious at all. The real sound problems are with the "commercial" type air pumps. They make it sound like take-off is imminent. I've used both types so I have first hand knowledge of the sound they produce. Hope this helps a little. West from Florida

It is kind of noisy, but not in a loud way. We have it outside behind the shop and it pumps water to the front deck. When it's pumping, I can't hear it when I'm watering plants. It isn't an on-demand pump, it runs continuously.

I have it in my bedroom about 6 ft. from where I sleep. No problems. One warning. I have baught several pumps through the years and just because one is quiet does not mean the next one of the same kind will be also.

Hi I did not finish installing the generator so I don't know how loud it is. When I go back to Florida this fall I will finish installing it and hope it runs quite.Sorry I can't help you. I can tell you it seems to be well made.

Ours worked relatively quickly, but we've found it to be very loud. Don't use it much.

It's not quiet. I used a sound level meter to compare it to a couple other units and it's literally 10-20 times louder. The sound it makes is also particularly annoying.
