Knifel fountain pump

Review: Works Perfectly! - I bought a little stone zen fountain from a shop in Sonoma about a year ago. It is hand made. The pump was always giving me issues and when the water would run low due to humidity or climate it always made a noise. I recently vacationed to Hawaii and when I came back, yep the pump had burned out. I quickly did a little research on it and discovered the pump would only last for a few hours with no water. So, I bought this one. It is waaaay better!! It is quieter, has more control over the flow, is a little more descete and has the added bonus of lasting 360 hours with no water. I am very pleased. Especially because when I bought the fountain the lady in the store said, and I quote "once this pump goes out, this fountain is done". Well Nope! She was wrong, thanks to this pump!
Review: Great pump - We’ve tried a few from desertcart for our bird bath. This one works very well, easy to install. I’m buying another one , they usually last a year. We dismantle the bird bath for winter anyway.

### ⭐⭐⭐⭐⭐ Great pump

### ⭐ Not Durable
*by P***A on November 13, 2025*

It worked until it didn't. Functioned ok since June but completely died in November (approximately 5 months) despite me conducting routine maintenance to keep it clean. It never did work as advertised about restarting after the reservoir went dry. It would usually continue trying to run after the reservoir went dry, and the pump would be hot. It always required me to clean it and bang it against something to get it to work again after running out of water (2-3 times).
