Question: Does the pump itself make much noise when submerged?
Document: I will make sure to mark this favorite so that when my other solar fountains go out, I can order from here. This is a little gem of a pump.
I ordered this pump to use on a small fountain I had. It wasn't strong enough to pump the water that was needed to make it work. So I am doing a small water display so I can use it. It works great.
This little pump is well made and the solar panel is very sensitive, even though it is much smaller than my previous one. The pump works like a champ, and the four stars is only because I could not find a switch to reduce the flow and avoid splashover.
I was surprised by the small size of the pump, my first tough was that it not going to work but when I put it in my turtle pond (about 4 x 4 feet) It works great, my kids love it and the water is more clean now. Jus make sure that you can install the solar panel where it gets DIRECT sun light or is not going to work. Very happy with the product.
This pump is just perfect for my little water feature. As long as the sun shines (and even when it's a bit cloudy) there's a lovely spray of water! I got this to replace a little electric pump that I had for a small fountain in my front garden. I often forgot to plug the other one in, and this little thing solves the problem.It is much more powerful than I thought it would be, and at first sprayed the water out of the fountain. Amazing!
Works but only in bright sun. This is very small....not really big enough for much more than a bird bath.
I haven't used it too much but it works when I've wanted it to, so far! Its amazing, really. Who knew the sun could be so strong?
It worked pretty much okay for about a month and then just died. While it was working, though, it was pretty powerful for such a small unit. Wish it had kept working, though...
I was skeptical that this would work because it was so small but it really does. I use it to make a waterfall effect instead of fountain and I really enjoy it.
worked well but the hot unrelenting sun here burnt up the solar panel .....got little less than half a season out of it.....may work better in North East or environment with not as much direct sunlight.
Answer: No, very little noise. At least nothing you can hear above the very nice fall of water. We have it in a 2' by 1.5' plastic flower pot in our front yard. I just hear the water.
