It is the most quiet on the market. Pair it with a Eheim canister filter and you will have to be really close to hear anything. Put it this way, I hear the air bubbles when the hit the surface. Remember, if you get the 500, you have to block off one output or use both.

When the water pumps there is a soft "humming" you can only hear in the bathroom where it is installed - definitely not loud and a pump shout off noise which is more noticeable.

it was "whisper quiet" when i first bought it several years ago...over time it has gotten noticeably louder when it engages and when it shuts off, you will hear it from the first floor. i recommend this pump---it hasn't failed me yet!

The pump has never woke me from my sleep. It runs off and on all night but is very quiet.

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...

Hello,The pump is not very noisy. It is like a humming sound. I hope this helps. I really like the Leg wraps.

Actually it's pretty quiet. The pump is located in the bottom of the unit so it's not by your ear.

Very little noise, Pump is submersible and filter has small water flowing sound. Can't hear it at all next to my waterfall.

You might have a piece of gravel or a small snail stuck inside. I would take it apart and use a cotton swab to see if anything comes out. It's one of the quietest pumps on the market.

I have 3 of them, they all vary in volume but all 3 are quiet. They make about the same amount of noise as a small gurgling aquarium pump.

I have the external pump attached to mine and it has a noticeable tick sound. Mine is under the sink in the cabinet and I still hear it. You get used to it after a while.

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.

When It's Flushed And Refilling It Does Make A Little Noise But It's Not Loud. I Hope This Helps.

It's very quiet. If it's cranked slowly it should be nearly silent. It won't bother anyone.

Very quiet. Mine is in the basement and I never hear it. I has mine for 14 months and the motor locked up. I had to take it an authorized repair place. Speller said that they would fix it or replace it. After 6 weeks, the repair place said that it was shot and it wasn't under warrantee. My original instruction manual said that it was under warrantee. I called zoeller and they said that it was warranted for 3 year from date of manufacture not date of purchase. Zoeller finally set me a new pump.

I bought this as a gift to my sister. She states that it isn't whisper quiet and that it can be heard in the next room, but it is quieter than the Lactinosh pump she used prior to this one. Hope this helps.
