VIVOSUN 1600 GPH Submersible Water Pump, 100W Pond Pump, Ultra Quiet Aquarium Pump with 15FT. Lift Height for Pond, Waterfall, Fish Tank, Statuary, Hydroponic

UPDATE 6/27/21: Since I most recently purchased the same brand pump at a 4500gph, but it won't let me review another gph pump, it will only let me update my review on the 1600gph pump: the 4500gph pump at 2 foot lift is pumping nowhere near 4500gph. Maybe 2000-2500gph. While that is an estimate, I compare it to the temporary 3800gph utility pump i put on the waterfall while waiting for this one to be delivered and the 4500gph is pumping out way less than the 3800gph pump did, so....I don't think this pump is anywhere near the 4500gph it claims to be. I would need to double that size if it's only really pumping half the gallons it says it does. Love the sturdiness of the pump and they have good longevity, but up the size if you want what you are looking for as far as output goes. This pump (1600gph) is so amazing I bought two! I use them in my koi ponds to pump water from the bottom of the pond up into a filtration system and out. This pump is tough and barely loses any gph when pumping at 5' head. Highly recommend it. Ran without issues 24/7 since I bought it in the spring, though I did remove it for winter shutdown, of course. It's pretty much maintenance free and easy to clean if needed (I never needed to) and it's outflow nozzle is adjustable; which I like. You can take the cover off, but it takes some finesse to do so as you have to line up the pump just right to detach the plastic cover. No need to cut it like others have said, you just have to take your time and figure it out. My only suggestion is that they make the step attachment for the outflow bigger so it can accommodate large tubing if needed. Other than that, A+

Great pump. This is my second. I bought the first one 3 years ago. It runs 7x24 from spring through fall, and I leave it in the pond over the winter. No issues with freezing or clogging. Cord is long and the pump has no issue pushing water through a ~10 foot hose with ~4' of elevation gain and delivering solid flow.

Good value for the price

So far, this has been the best pond pump we’ve owned. It’s worth the extra few dollars. It doesn’t have as many attachments and there is no sponge filter however it clears the pond water. I’ve had to remove it when it’s gotten colder and put it back in when it’s stayed warmer and I’ve been amazed at how quickly it clears the water. We’ll see when summer rolls around and it’s running most of the time but overall I’ve been very pleased. Update: very disappointed about not being able to remove the impeller so that I can clean it. I have looked up more detailed instructions in case I was missing something. The tabs are hard plastic and there is no movement when I push one in. It is difficult to get ahold of the porcelain shaft with needlenose pliers and I fear I will break it.

I purchased this pump for a 400 gallon fish pond with a small waterfall. I am very pleased with the suction power and with how much water this pushes over the waterfall. The pump is very easy to clean, as well. I like being able to remove the housing and clean out the impellers when necessary. Have only had the pump for about 6 months and we are very pleased with it. It's quiet and operates as described. Our pump runs 24 hours a day / 7 days a week. Hoping to get good usage over time.

Great pump. Got the 3 year warranty. 3 years and 2 months later, the thing was fried. Ordered or 2nd one. Get the warranty people, just in case!

Little big for our fish pond.

This is a delayed report but need because of a problem I encountered. I initially felt tat the unit worked well and and reliably even though it is in a duck pond. But recently it stopped working and when i checked it I found water coming back out of the strainer area and when I took that off I found a lose part (pic). It seems that the impeller rubbed against the impeller chamber cover and eventually broke the center section off. The diagram has the area circled. This stopped the proper water flow. I managed to make a new piece to fit the hole but I don't know how long it will last. The impeller assembly still works. I have another larger version of this pump and have not had the same problem yet.

Una excelente marca,y he visto el crecimiento de mis tilapias

I bought this in March 2024, over a year ago and it's still running great. Even kept it running throughout the winter. The one issue was, when I attached a filter hose line to the thread intake, the casing broke. Doesn't appear overally strong, so I don't use an external filter but it doesn't appear to need one. I would buy this pump again without hesitation.

Read great reviews. Received product damaged. And now dealing with the return process. It’s a bi pain to return item and order another and wait for a refund instead just making it one step

Great pump works great and very well built.

I didn’t even get one year use out of this only ran 12 hrs a day
