Mine personally has never done this, but it's possible I might have just got a good one. I also bought mine a few years ago, so maybe they updated something on the pump recently that didn't improve its performance? Did you try swapping out the oil? Maybe you're getting pumps that are coming with expired oil?

I mounted mine directly to the inside of the cabinet, and the noise is just a small clicking sound once every several seconds. It is only noticeable when it is quiet and you are standing near the pump.

Could be the cogs inside the drive wheel are wore out... It would make a loud clicking/grinding noise. No unusual sounds.. Could be the activator lever is not connected properly

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.

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.

Gee...sounds like a faulty product. Shouldn't do that. Try a tiny bit of cooking oil on the gasket that is on the pump and see if it's just a dry gasket. If that doesn't do it...return it.

Mine did that too from day one. The box it came in was damaged and I assume that is what caused the weird noises. It wasn't worth the time and money to ship it back so I just used it until it started giving me uneven heat. Then I junked it.

Yeah it sounds defective. I would suggest calling Amazon to see if you can get an exchange.

I found cleaning the pump intake solved the problem. When I took my out, it had cat hair plugging the intake side. Once I got it cleaned out, it works like new!

Your water tube is NOT far enough in the filter pump! Mine does the same thing after I clean it, makes a hell of a racket! Then I just 'bump' it down gently but firmly and the noise stops!! Just make sure that the wheel is set properly into the pump motor. That should resolve the noise problem!

It could be the pump rotors are beginning to rust and expand like I mentioned in my review. When this happens, they start scraping and making noise, and the water circulates less. There is not much you can do about it.

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.

My pump sounds like it has a small rock in it when it is working. I called Tetra and they said they would send me a new pump but it and the light look like one unit. I would call Tetra and ask for a new one.

I have the same version but with a metal chassis and noticed this whine. I'm going to look into a replacement. It makes the noise about 20 seconds after plugging in the power.

It may be "water hammer." Try this site for a solution: http://home.howstuffworks.com/home-improvement/plumbing/how-to-fix-pipes5.htm

I would like to know that, too. Mine has started making a noise and I don't think it last ten years.
