Is there a way to keep the pumps from knocking? I just received this today and hooked it up to my two new Hydor Evolution 600GPH and it knocks loud.

No. The manufacturer has indicated the popping sound is the impeller hitting the housing as it starts up, which Hydor says is inherent in their 120v AC power heads. They recommend running the pumps longer so it will pop less, but you'll still hear the knocking if you hear it now. Hydor's only recommendation was to switch to their DC pump and controller system, which does not have the issue with spinning backwards or striking the housing. The Smart Wave controller cannot fix the issue with the power heads.

I'm not quite sure what you mean by "knocking", but the Hydor Wave Maker simply transitions power to and from the power heads. It must be the heads themselves. I have 2 Hydor power heads and I heard a slight click in the beginning but nothing now...at least quietly enough I don't even notice.

Make sure the tube going into the pump isn't kinked and fits nicely in the out spout. I don't think my is noisy. My dog and my two cats use it just fine.

Depending on where the pump is sitting, it may be vibrating on the surface. It will make some noise, but compatative to other air pumps this one is quiet. You can also try putting a washcloth underneath it.

I've not actually experienced this. You might have a defective pump, although I can't be certain.

We have actually experienced the same issue with the banging sound. It isn't consistent from use to use or even within one session. It doesn't appear to alter the performance, but it is certainly annoying. It isn't clear what the cause is so I'm hoping it isn't causing internal damage to the machine.

my pump is quiet however sometimes it will touch the top sides of the lid and make noise. I am just mindful of that and will move it accordingly.

It shouldn't be that loud! Mine is roughly a month old and it's only "noisy" when it it isn't full of water. Try filling to the max, if that doesnt help try cleaning the motor. Other than that it could be a bad motor......

There is a propeller/screw type element at the end of the curved pipe - pull that pipe and element up and off the unit... clear any debris in there and make sure that the propeller/screw type element is seated nice and tight and straight and not fouled with any hair or other such stuffs... then re-seat the components. That should stop any rattling... What kind of noise are you hearing? It's not absolutely quiet, there is a bit of splashing that you can hear.

I add water every day because the top of the fountain may appear full, but could actually be low in the bottom. The day mine started making a noise, I opened it up and there was only about an inch of water in it, but top looked full. This is probably how others had the pump burn out on theirs, or seemed too noisy. Just a heads up....

The pump is not that loud. Mine is in the garage, so the sound is not an issue for us. It does make a clicking sound every few seconds while it is refilling the tank after you use water and also while it fills the tank. Otherwise, it does not make noise unless it is in use. Hope that helps!

Take the unit apart and pull the little pump out and see if its clogged with debris. When the pump get clogged it will start getting loud. Also if there is air getting in it will be noisy so make sure to fill the enclosed compartment(where the filter sits) is filled with water first. Hope this helps.

I did not shake mine so I cant tell if it makes noise. Previous answer sounds right. If in doubt, call the factory. I am very pleased with the filter. You might want to buy a brass fitting for the water connnection. I dont like the plastic connector. I had a brass fitting from my old filter that worked perfectly.

I have this same problem. It's loud and I can't for the life of me figure out why it started or how to stop it. I'll have to buy a new machine (not this one).

My pump is in the basement. You can hear it but it becomes background noise. If you are looking for a silent pump, good luck!

When I start hearing the pump, my water level is low. Keep it filled up and you should not be hearing that noise! It sucks up a lot of water but then, it puts out the amount of steam I need for my quilting projects. I have to use a flashlight to be able to read the water line....must be bad lighting at my ironing board!

It is the permeate pump causing the noise, the motor makes noise and then you hear the pressurized flow run through the lines. I bought this unit because I thought I needed a permeate pump being on a well, and my water pressure is perfectly fine. It actually caused too much pressure and made my faucet leak which was the main reason for my return. I now have the exact unit without a permeate pump and I couldn't be happier. If your water pressure is around 60PSI I would return this and get the non permeate unit.

Since this was a gift to my Daughter in Ca. had to wait for an answer, this is what she said..hit it about 10 times, then you'll hear the strong bursts on the next few pumps. 3 pumps works for me. Good luck!
