GROWNEER 550GPH Submersible Pump 30W Ultra Quiet Fountain Water Pump, 2000L/H, with 7.2ft High Lift, 3 Nozzles for Aquarium, Fish Tank, Pond, Hydroponics, Statuary Black

Pump was a replacement in a waterfall we got from Home Depot. It works just fine. More gpm is not always better as it can cause excess water to splash out and require more refilling of the waterfall. This pump provides a steady flow with no spillage.

Works great with my large fountain. I have it low since it will produce a lot of water if you have it high. I don’t have enough space for my fountain to do that, so didn’t want to waste water. Product is great and exactly how described.

The media could not be loaded. Perfect fit for my small outdoor fountain. Great water flow and better than the pump that originally came with it, and failed after several years of use. Great power and water output

Bought this to replace a fountain pump that died. The former pump was the same 550 gpm as this that I got to replace it.The upside is that this is super quiet and very, very strong.The downside is that despite turning the flow adjustment knob, the flow strength stays very, very strong.Water splashes everywhere outside my fountain and within hours, the pump starts to make a gurgling sound indicating that the water level has dropped too low.I took the pump out of my fountain and sat it in a 5gal bucket to test. I removed the tubing from the output valve, and measured the stream strength and height on high flow, med flow and low flow. There is literally just about an inch or two difference in vertical stream spray when on high vs when on low.I even bought a separate flow adjustment nozzle and inserted it between the pump and the tubing.This worked great for about a day. The next day I noticed the water stream was flowing strong again and when I checked on it, I found that the water strength flowing through the flow-control was strong enough that it pushed the valve back to the full open position.Yes, this pump is strong.For my use in a small-ish outdoor fountain, this results in way too much splash outside the fountain and well basin which drains the well within several hours.If your fountain or pond is large enough that overspray won't deplete your water level and you're looking for a strong, silent pump, this one's for you. Unfortunately my fountain is too small and this didn't work for me.

I have an outdoor water fountain and from time-to-time I have had to replace the pump. I have consistently replaced it with a GROWNEER 550GPH Submersible Pump 30W Ultra Quiet Fountain Water Pump, 2000L/H, with 7.2ft High Lift, 3 Nozzles for Aquarium, Fish Tank, Pond, Hydroponics, Statuary Black. In past purchases the pump came with a heavy-duty power cord with 3-prong plug. The new pump I ordered ca M e with a light-weight power cord with a 2-prong plug. For an electrical device that is both submersible in water and exposed to the outdoor element, I found this "change" in construction to be very disappointing. The next time I need a new pump, I will shop around for a better cord.

This is a powerful little pump! Pay attention to the GPM. This one will shoot over the patio roof if I don’t adjust it hahaha perfect.

Works well and have been using it for a while now.

Pump works great --- Used outdoor for fountain my bad ---did not see length of cord only 5'9". Concern is length of cord, My electrical outlet is 8' away, now need add extension cord. I would not have purchased if I read total description
