Mine is just a little louder than a factory pump. I did mount it with rubber isolators though.

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.

The pump tends to whine a little while operating, similar to what you may hear in some gm trucks. I have used it several times with good success when doing various ls-x swaps. Never had an issue with the noise being unbearable. What is your application and mount point?

These pumps need to be force fed or have a very low restriction feed or they will cavitate and get very loud. If it's running as a stand-alone pump, it will need to be mounted near the bottom of the tank with minimal bends in the supply line. Otherwise, you'll need a secondary pump to feed the 044.

I could have just gotten a lemon. But the device sounds like it is over working. Air pumps do make a slight noise, I have had fish tanks from salt water to warm fresh water to cold fresh water and have used a number of air pumps (sorry I can't remember the brand names). This one is the loudest I have come across. I am definitely going to go with another brand in the future. Hope this helps.

Assuming the pump itself is OK, it tends to be noisier when the voltage is low or when the pump mounts are loose/vibrate.

Yeah, i have the same buzzing noise. I took the car to a car-audio professional store and they told me that the sound is from the device, not from the car because sounds even with the engine off.It starts to annoy me a lot, if you know what could be the solution i will appreciatte.

My sound is pretty loud. To pump up the volume u have to hold the button down. Mine is so loud that my so in his room is begging me to turn it down. I don't understand what happened with yours. I have no problems at all with mine. And guess what!! My phone volume is turned to half way and my speaker is still loud. I never turn my up all the way up. The speaker just takes off with its loudness. Love it�

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.

Yes, I use to have a pretty loud hammering noise when my pump shut off, but now it is silent. I cannot recommend this enough if you are sick of hearing the water hammer sound.

none of them are particularly quiet in my experience with a usual rough vibratory tone made worse if they are operating under any back pressure. Run it free in a bucket and see how it sounds. If still loud then that's the sound of the pump.The maxijets are worse

K. I got this for a second house. I haven't been there since installed, but my nephew is saying that it is loud. Reach out 2/1, and I will give you an update.

I don't remember the noise being unusual or too loud. I installed the pump at my daughter's house and she has never complained about excessive noise

You will hear a small bubbling noise from the filter, however, the air pump is usually just as loud. So all-in-all, I would say, not very loud.

I'm sorry you're having trouble. The first fountaini bought recommended you leave it unplugged for a few days when introducing it into your cat's environment so they can get used to it. Maybe that would help. If it's used it could be that the pump is a bit noisy but the sound has never bothered my cats. I hope it works out.

It's under the water. There's nothing to hear. If you have the outflow connected to a water feature, you will hear water noises. I have my pump in my indoor pond for the winter; it's silent even when you are next to the 100 gallon stock tank it's in.

This pump is about as loud as a new lawn mower. If you put a deflector wall around it, it would help some. It is a great pump.

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...

Not very noisy at all. We use the pumps for a race car driver's cool suit (circulates coolant through a vest to keep the driver cools in a 150 degree environment) so we don't care about noise. But it is almost impossible to tell if the pump is running without touching it.

No, should not be that loud (but mine is louder than I would like). Mine reminds me of my old fish tank air pump in loudness. Sounds like yours may be vibrating inside of the unit.
