CWKJ Fountain Pump, 400GPH(25W 1500L/H) Submersible Water Durable Outdoor Pump with 6.5ft Tubing (ID x 1/2-Inch), 3 Nozzles for Aquarium, Pond, Fish Tank, Hydroponics

Thought pump had too much pressure for my freestanding waterfall feature, but the flow is adjustable by turning the rotating tab on back of the pump.I like a serene sound not a rushing waterfall, so great option.If you have decorative moss or debris that can get in your water, be cognizant it can get caught/sucked in the rotating tab on the back of the pump, but thankfully the tab has plastic bars that catch debris and you can clear it easily, if needed.I have to turn the flow down on my pump or the water will shoot out the top of the waterfall.I have about a 4' rise from the holding tank to the top of the waterfall, so the pump is powerful for my application.Make sure to unplug the pump before you take it out of the water to clean or clear it. Needs to be submerged in water at all times once powered on.I know some people have complained this pump is loud, but I realized if I keep the pump away from the walls of the holding tank and toward the middle of the tank and firmly sitting upright (with help of suction cup feet), it is quiet.Pump also comes with a few different sized water nozzles that attach the pump and hose.The hose is longer than I technically need. I could cut it down some, but I'd rather not (just in case) so I let it loop behind the tank and up through some rigidity bars on the back of the waterfall.I'm glad I purchased this pump, the price is right and it works very well.Build seem sturdy.

The media could not be loaded. Great pump! Plenty of power; in fact too much power for our fountain. I had it turned all the way down but the bubbler was still too powerful and was scaring the birds away. I used a tip I saw in the other comments and rubberbanded a secondary filter around it which cut down the water flow enough for my use. BTW for the pre-filter I used the rectangular scrubbing pads from the dollar tree; 6 for $1.25, works great! The water in our fountain only needs to travel about 2 feet. I could have bought one with less power, but everyone knows more power is better! Hahaha! I can't speak to longevity yet but I will update if it disappoints me.

Works fine but after a few months it was shorting out and I got zapped taking it out of the water.Should shut off if theres a short but nope.Be aware!

works well

The media could not be loaded. Can't comment on longevity, as I just installed it.The lift / water movement rate is excellent on my little fountain, better than the original one which died after only one year of useThis pump, as with all others of this type, is super-easy to install.I recommend this particular model -IF the gallon-flow & lift are good for you- if you have a fountain that has a very small space for pump placement; I had to order three different ones before I found the perfect fit: our fountain has the smallest dang space for the pump in the back, in a tiny little 'cave'. All others were just a skoosh too big to fit, by 1/4 to 1/2 "This one has a stronger flow & higher lift listed than my old one did, AND it delivers per description, that's for sure!For reference, my fountain is about 3' tall for the lift, the original pump was rated for 5' lift, but never did flow as well or as fast as this one, as you can see it does in the videoFor the sale price I paid, @20.99 it's the best value on Amazon for these particular specs. Hope it lasts longer than a year

I received my pump on June 28, 2025. Installed it the following week in my small water feature. It’s now August 20, 2025 and the pump no longer works! I’ve cleaned it and tried all of the suggested troubleshooting and still doesn’t work. Very disappointed.

Great little pump for outdoor fountain. Nice and relaxing to hear the sound of the falling water.It was a much better price than the nursery had on theirs. Perfect fit for small pump area in fountain.

I picked up a pair of these pumps to use as water pumps from small reservoirs on timers. Functionally, they work as expected. I only have about three feet of lift to overcome so they are plenty strong enough for the job. Main 1/2" line to multiple drip emitters stays fully charged throughout the active period with no issues.That said, one of them started rattling and clanking by day three. It sounds like a box of loose parts while running so I have to float it on a plastic lid in the middle of the metal reservoir to avoid insanity. I've already ordered a different brand of pump to replace it because there is no question that it will be dying fairly soon.Not recommended due to failed unit. There are a lot of options for pumps. Get one that doesn't feel like you're gambling with the lives of your fish or plants with each order.
