VIVOSUN 800GPH Submersible Pump(3000L/H, 24W), Ultra Quiet Water Fountain Pump with 10ft. High Lift with 6.5ft. Power Cord, 3 Nozzles for Fish Tank, Pond, Aquarium, Statuary, Hydroponics Green

Simple little pump, strong, works great, perfect for my garden water feature.

Sound level is very good for a pump of this flow. I bought it to use in a Low-Pressure Aeroponics setup - emphasis on learning about LPA without breaking the bank. The outside casing makes it look like about 50 other water pumps carrying various names at similar price points and advertised flow rates, but it puts out more than twice the water of a nearly identical-looking 640GPH pump, and my misting heads can be tightened enough to produce very fine mist without stopping the flow altogether. This little 800GPH pump is likely a little less powerful than it claims, as the lift height is stated at 10', and at 6' the water flow is quite restricted. But for a small, cheap "testing" setup, it works great even with 10 misting heads on 1/4" PEC irrigation tubing. The fittings seat and seal well on the pump outlet, and a spare suction cup is included in the box. Also of interest, the noise level is actually lower than my 640GPH pump. Wattage is as specified, with very occasional increase/decrease, and connecting it to my 1500VA/900W UPS system barely increases the load, dropping the 450-minute "unloaded" reserve capacity by just 12 minutes. Running only this pump on it I would have more than 7 hours of water flow if the power goes out. The pump itself is about twice the size of the 640GPH, and more than twice the weight. Mounting it to the side of a reservoir requires an absolute minimum water depth of 5.5", and with a "Y" splitter in the outlet for balanced pressure in a looped irrigation setup I recommend placing one of the nipples on the pump outlet and using tubing to connect the splitter so you can lay the splitter flat in your reservoir and place the pump upright on the bottom as there are water intakes that must both be submerged on both ends of the pump. Using 1/4" irrigation tubing without a cap and free-flowing, the inlet flow control at the front makes no noticeable difference in the amount of water flow, so if precision flow is required you'll need inline valves, but for my setup, adjusting the misting heads is enough. So far, I'm quite impressed with this little guy, and no longer worried about finding my plants dead from lack of hydration or nutrients. If it lasts awhile, this will have been a great buy - one I highly recommend for smaller LPA hydroponics setups or even a 3-bucket tower or up to 10-bucket Dutch Bucket system. At this price point, I can keep a couple of these on the shelf in case of failure, and if they last 6 months or more in use, they'll be well worth the cost.

This product is amazing. It works like a real pump should work but in my case, unfortunately something or maybe some lightning or something that I fell yesterday probably showed it out. I have no idea.

I've purchased two now - first on 2023-01-22 and the next just now on 2023-02-25. The second one is to "try my luck" of sorts. The first one worked fine but seems to have suddenly started giving issues. Less than a month. The problem is it keeps shutting off by itself. It's fully submerged and there's no blockage or debris, but it seems to be shutting off. Checked and double checked but nothing. It does work - mostly - but I figured maybe I just got a bad one. The product has lots of good reviews and is the current #1 item in the category - so I've gotten a second one to see whether or not I just had bad luck. Hopefully the next one will do better and not shut off randomly. It does seem to come back on - not sure if it's overheating for some reason... Still giving it 4 stars because it works great when it does work. Will review the next one fully when I get it and test. 2023-05-16 After writing them about the failures I received a full refund for both. It works really well when it does - but there just may be some issues with the one you get. The customer service is excellent though - so you could either get a refund if you're so inclined or have them send a replacement.

Our fountain really looks good and sounds good. It has 4 bowls and the water fills a bowl, then spills over into the next bowl. I like the LED lights in the bowls, and I put an LED spotlight on it as well. We sit out on the deck and it sounds nice on a quiet night and the lighting is just right. We enjoy it in the daytime as well. I would give the fountain 5 stars but for 1 thing. The pump was pitiful. It started out well but after a couple of months it became very weak. For the winter I emptied the water and did not set it back up until the middle of March. It was so weak that the stream was not steady and it splashed, wasting water. I may have been able to get another pump from the seller, but didn’t bother. I ordered a different pump from Amazon. It is this VIVOSUN 800GPH Submersible Pump(3000L/H, 24W). Is it too much for this fountain? Yes, but it was only $25 and I set it ¼ of the way open, so it doesn’t have to work very hard. I like that I can dismantle it if it needs cleaning. It puts out a steady stream and does not splash. It comes with 3 sizes for the tube and one fits just right. Even though we have two bird baths out back, the birds like this fountain also. We used to have a typical 3-tier fountain that splashed terribly and kept the bed that it was in wet. Then I tried a cascading fountain and pieces of the slate broke off. But this fountain is much better. With the steady stream (with the new pump) it doesn’t splash.

I have an outdoor water unit and needed a new pump. This is the one that fit great , most powerful and quiet. In addtiion it was easy to set up. Was very happy with the price and fast delivery.

I’ve been using the VIVOSUN 800GPH submersible pump for a few months in my hydroponic setup. It gets the job done, but there are a few things to be aware of before buying. Pros: Decent Flow Rate: The advertised 800GPH seems fairly accurate under optimal conditions. It moves water efficiently and keeps circulation consistent. Quiet Operation: It’s pretty quiet—definitely not silent, but the noise is minimal and unobtrusive, especially when submerged fully. Includes Accessories: The three nozzle options are a nice touch and allow for some customization depending on your setup. Cons: High Lift Exaggerated: The 10ft lift is a bit optimistic. In real-world use, it struggled to maintain decent pressure past 6-7 feet. Durability Questionable: After about 2 months, the output noticeably dropped. I cleaned the unit and impeller, but performance didn’t fully recover. Short Cord: The 6.5ft cord is okay for small setups, but it was a bit restrictive for my needs. You might need an extension depending on your layout. Overall, it’s a decent pump for smaller systems or hobbyist use, but I wouldn’t rely on it for anything critical or large-scale. If you’re looking for something more heavy-duty or long-lasting, you might want to invest in a higher-end model.

Fantastic pump. I bought a new outdoor fountain and the supplied pump almost immediately failed. So I bought this one and it worked perfectly. I do have to keep the intake 90% closed as it’s a almost too powerful.
