I bought this pump to replace a 5v USB-powered water pump that came with a small pet water fountain. The size and dimensions are similar enough, I thought this pump might suffice. The other requirement I had is that the output nozzle be removable. The fountain used a spout that directly fit into the old pump and so I needed that rubber hose fitting you see in the pictures to be removable (and it is). While the pump does work, it's wasn't a perfect fit, and in its defense, it isn't advertised to be a replacement for my application so I have to cut it some slack. The good news is it does work and has sufficed. And I did have to make use of the variable flow dial on the side. Wide-open, it flows about twice the amount of water the original pump did. So I had to turn the dial down to its lowest setting. And with this setting, the flow is very acceptable. However the main complaint I have about the pump is that it is not quiet like the original pump was. It's got a noticeable hum to it that is easily heard in a quiet room. Fortunately, the pump is located near the kitchen. And with the microwave going, sink water running, or any other activity going on, it's easily ignored. But it is something to be aware of if noise levels are a concern. The other problem I had is the pump's output hole is slightly larger than the original pump. So the fountain's spout that goes into the pump didn't fit snug like it did with the original pump. I would have thought the pump output diameter would be a standard size, but it is not. To fix that, I just wrapped the bottom of the spout with tape to make up the difference, and that has worked. The other problem is the original pump's power connector was a USB connection which fit down the fountain basin's provision for the power cord. However the 120v connector wouldn't fit. So I've had to run the power cord out the side of the fountain instead of through the provision and out the bottom of the fountain. I hadn't counted on this being a problem. Again, this isn't a problem with this pump or its advertisement. It was just a minor incompatibility with me trying to use this pump in an application it wasn't really intended for. The pump does come apart just as pictured to make cleaning easier which is a plus since the water in these fountains can get growth in them in as little as 3 weeks. So would I buy this pump again for this application? Probably not. I would try to find a closer compatible match. However if I had some other generic need for a small submersible pump where sound levels weren't a concern, I would have no problem repurchasing this pump. Had the listing indicated this was a replacement for the pump I had, I would NOT be giving the pump 4 stars. It would get a 2 at best. It gets 4 stars because I do believe it satisfies all the requirements of what it is advertised to be. If it were quieter, I would've given it 5. The longevity and durability of the pump are still to be determined. As of this writing, the pump has only been running a few weeks. The previous pump lasted about 2 years. So if I get 2 years out of this one, I'll definitely consider myself as have gotten my money's worth from it.Read full review

Unbearably loud. I bought this to replace a pump in my pet's water dish and it's so loud that it's unusable. I can hear it from the next room. I know that sometimes you have to let a new pump run for a while until all the air works out and it gets quieter, but I let this go for a week and it was still just as ridiculously loud. I wound up just having to unplug it because it was making me insane.

It is the perfect size for the bird bath I made. The power of the pump Is just right not too strong of a water flow plus you can adjust the flow rate. Just great for a small project. Will post pictures when have finish My water fall.

For small tanks that need some water transferred these are just fine. Side to side transfer is good. The downside is they have very little lift capacity, 12" at volume. Over that and its a trickle. So for a small fountain they might be fine. Even so, they are good little pumps.

I have a small cat water fountain and my large dog insists on drinking from it which in turn burned out the pump that came with the fountain from him drinking it dry. After installing this one I know I don’t have to worry about it burning out when he drinks all the water. It keeps running, louder but still running.I just add more water and it’s good to go! I’m hoping he will like the large water fountain Ives ordered for him and will discontinue running the cats water dry! Lol! I did order two of the pumps so I would have a back up one.
