No, mine is very quiet. I've read in the Rasa thread some people have had good luck by adding one drop of dish detergent which acts like a lub (so they say). It also is suppose to help eliminate the micro bubbles that collect. Bleeding does take a while, I let mine go for 3-4 hrs on new system bleeding. I'm no expert here, and these are just things I've read. Take them only for what there worth.

I've also read there's been a few of these kits that need to have the pumps replaced, which is more of how I'd think things would go. Sorry I couldn't be of more help!

Unfortunately, the pump either works as expected or is very noisy. I had a noisy one - dish soap did not help either. I finally had to get it replaced. I would try the dish soap method though. Take it out - pour a few drops through the pump outlet. Let it sit on the side for a few min, turn it the other side and let it sit. Then try it out. Your water will get all foamy, but just leave the res cap opened. All you should hear is the water whoosing due to bubbles.

EDIT: Also make sure it is mounted properly. After I got my second pump, I occasionally can hear the pump. Goes away once I move the case a bit. I finally had to jam some foam on the sides, top and bottom to isolate it from the case more. All I can hear is a slight hum just like I would expect from a pump - and that only if I get real close to it. The first pump I had, I can hear it from outside the door of my room - about 10ft away.

I second using dish detergent and just being patient. My pump was silent, then loud, then silent, then loud again. It was so loud one time I could hear it across the house late at night with nothing else moving around. Now, it is completely silent. Use some blue Dawn detergent, and no more than two drops. Shake the case around a bit, and let it sit for a while. Eventually, the pump noise should go away.

Hmmm, I have a really noisy pump (not from a rasa kit, but it's the same pump), I had assumed it was just the mounting since it wedged into a little server case. I might review that.
