VEVOR Utility Sink Pump, 1/3 HP, 120-Volt, 2900 GPH Flow, 25 ft Head, Under-Sink Sump System With 6 Gallon Basin, Automatic Laundry Drain Pump, 1-1/2" NPT Outlet, Black

I was very impressed with how sturdy this thing is. Its solid, easy to assemble, and works amazing. it will drain itself in about 6 seconds! it has some power.

Arrived on time, packaging was ok as everything is contained inside the pump box. Upon opening the pump box, everything is packed nice and in bubble wrap.This is where it begins to suck.After opening the bubble wrap that contains the uplift tube and check valve assembly, I found the check valve to be detached. You can easily see there was barely any adhesive used to attach it.I reached out to Amazon and they directed me to Vevor. Customer service said they'd mail out the part. They email every three days and just say the same thing, we are sorry, blah blah they are working on getting the part, etc.Tired of waiting and figured I'd just get it running.The upflow pipe is not a standard size (it's a pvc pipe milled down on both ends with a fernco attached to the check valve) so it took a bit of trial and error to find a check valve that could be adapted to work.There's no real seal where the uplift pipe meets the box. I lucked out there I guess as it doesn't leak there (yet anyway, pump has only been used 3 times)The biggest issue is that the seal that goes in between the top and bottom of the box leaks all over.I was careful not to over tighten these screws as I didn't want to strip out the plastic.I went back and tried tightening them more but same result.I saw another review on here where someone else has the same issue.I'm not sure what to use to seal this box so it doesn't leak but I'm already invested into it so I'll just figure something out until it dies.I'm literally just using it for a utility sink in my basement for aquarium water changes so in my case it's not a total loss.I went cheap and well as usually goes, wish I didn't now.The pump itself flows a lot of water, the rest of it though.....unfortunately not great, really not even good unless you are OK with a wet floor and enjoy the modifications necessary to make it work.

Easy to install, works Great, very happy with the design

There is some assembly required but it's rather easy.

Seemed great until it was fully installed by a licensed plumber and now I’m finding leaks near the gasket area which is screwed on. Too late to return. avoid this product as this is a poor design.

Well built. I would highly recommend using Fernco’s on the pipes coming out of it to enable maintenance when needed.

The original review is below.In actual use a problem has arisen that I'll have to try to resolve. The top lid of the housing is held down by several self-tapping screws, squeezing a plastic gasket to supposedly form a seal. Sadly, this gasket really doesn't work very well. Another feature of the assembly is that the internal output pipe from the pump is not really sealed to the output port in that very same lid. What's happening is that when the pump motor runs, it sprays water firmly all around under the lid, seeking any potential exit points at (you guessed it) that gasket.Long story short, when the pump runs there's a driip-drip-drip of water streaming down the outside of the housing. More than likely I'll have to invent my own gasket to keep the pressurized water inside the box.Not a good design.=======================================================================I previously had installed a Simer pump under our basement utility sink. Actually I had three of them, the first two were duds. About a month ago I put some brackish water into the sink and the Simer pump seized. Done. Out it goes.In comes this new Vevor Sink Pump. What a breath of fresh air! Easy to plumb, worked right away, and best of all it's able to handle water that might have a few small particles in it. My only reservation is that the unit is a bit large to fit under the sink, but I did manage it.All is good, ready to stop thinking about this thing and just use the sink. Never going back to Simer.

The pump was leaking from the day of first use. Damaged my cabinet as well. I have to pay $500 to have it removed. Amazon put it on Vevor and Vevor is putting it back on Amazon. It's a total waste of money and time.
