About this item

  • POWERFUL SUMP PUMP: The 1/2 HP submersible clean/dirty water pump boasts remarkable performance, effortlessly pumping up to 3400 gallons per hour at a depth of 5 feet. Equipped with a formidable maximum lift capability of 31 feet, it confidently handles even the most challenging water transfer tasks. The pump's robust design allows for a substantial immersion depth, while its lengthy 10ft power cord ensures ample reach for flexible deployment across varied distances.
  • AUTO FLOAT SWITCH: The sump pump, featuring a float switch, functions autonomously in response to fluctuations in water levels. When the water level dips below 2.2 inches, the float switch triggers the pump to automatically cease operation. Conversely, as the water rises to a predetermined start level of 10 inches, the pump springs into action, resuming its water removal duties efficiently.
  • TOP SUCTION DESIGN: The built-in top suction design proficiently prevents air locks and screens out impurities, guaranteeing continuous and uninterrupted pump operation. Coupled with a round, stable base and an enlarged turbine flow passage, this pump excels in confined spaces, making it the perfect choice for regularly pumping small volumes of water with ease and efficiency.
  • Convenient Design: Equipped with three versatile outlet diameters (3/4 inch, 1-1/4 inch, and 1-1/2 inch), this utility pump seamlessly adapts to diverse hose sizes, catering to varying flow rate requirements. Keep in mind, to accommodate greater flow volumes, opting for a wider outlet diameter is crucial. Additionally, this pump boasts a motor integrated with a thermal overload protector, ensuring safety. In the event of the pump stoping operation, it's possible that the protector has been triggered as a safety measure.
  • WIDELY APPLICABLE: The powerful drainage pump tailored for tackling flooded basements, hot tubs, cellars, water tanks, confined crawl spaces, window wells, swimming pools, garden ponds, sump pits, rain barrels, and a wide array of water transfer tasks, ensuring efficient and reliable water removal.

Our washer is in the basement, and it empties into a wash tub, which drains into a sump. The sump pump died and the basement flooded. Got this the next day and hooked it up. It pumps twice as fast as our old one.

I want to point out that this pump rated 1/2 hp weighed only about 9 lb 10 oz dry, while a cast iron pump rated 1/3 hp weighs in at around 24.5 lb, +/- about 2 oz for both measurements. I tried to hold the cords so as to weigh just the pump enclosures. This uses only about 177 watts/243 VA running open flow, according to my Kill-a-watt electric meter. VA is important when running things on generators and inverters, which are often seen in solar and mobile installations. The motor indicates 5 amps, which is between 3/4 and 1 hp, so I don't know where 1/2 hp came from. Then I put it in the sump pit and, with a garden hose attached, read 380 watts/405 VA pumping water up only a few feet, but through the slender 1/2" hose. It moves water fairly decently and still runs quietly. No power source I used had trouble. One plus to that low amount of energy usage is it runs fine on a decent power inverter, one that cannot start the heavy iron pump. I added 100' of 12 AWG extension cord, and it still ran fine. The vibration is minimal so far, but it's also fairly new. It's hard to tell how hard it would push water in this setup, but so far it works.This could be powered from a car inverter or the neighbor's place if need be. It's nice to have options. It's nowhere near as powerful as the heavier pump and, unfortunately, probably wouldn't keep up with the spring melt here, which won't be for months, if we even get one this year. It's handy as a backup, or if the power goes out, or probably fine if the sump isn't needed all that often. I do like how quiet it is.The ad mentions draining hot tubs and pools; it would be perfect for that, and the garden hose connection is already included. The impeller may be replaceable; there are 9 Phillips head screws holding the bottom cover in place. That appears to be about the only user-serviceable area, if it is intended for that. It's a much different style than the common solid cast iron pumps. Works fine so far. A piece of wire keeps the switch closed so it can be used with an offboard float. Such a float is highly recommended in sump installations as the pumping window, or amount of water pumped with each cycle, is quite low with the original float. For a single sump pump installation, I'd go with tried-and-true iron, with a spare on hand. This lightweight pump is easy enough to put in and out of place should another pump, perhaps underneath it, need changing. It fits well too as a secondary pump in an existing pit with now two pumps and two floats. The original second float is for an alarm that may no longer be needed.

I have this set up in my crawl space to control flooding under my house. It is a very powerful pump. I highly recommend!

Worked great at first (especially for the price point) but stopped working after three months.I kept mine in a fountain, and used maybe 1-2 days a week.Probably best to spend a bit more for one that’ll last longer

I ordered this as a spare for a nearly 20 year old sump pump. Little did I know that I'd need it within a couple of weeks. We had a rainstorm that would normally make the pump come on and when I didn't hear it start, I went downstairs to find the sump well nearly full. I pulled out the old one, and by pure luck the fittings were a direct fit. It took maybe 15 minutes to swap and then the water was pumped out quickly. I set the level fairly easily and now it seems to be working as planned. when the water rises, the float reacts, the pump kicks on and the water goes out. All seems well again.

There is always a possibility that the electric grid power will be out at the time that you need to use this sump pump. That means that you will be running this sump pump on a generator, either fuel or solar/battery. I tested this sump pump twice for its initial draw using my Bluetti AC 180 solar generator. The average initial draw was 715 watts, which was less than what I expected. After a few moments, the load dropped to 500 watts. The sump pump is rated at 5 amps at 120 volts with an assumed consumption of 600 watts, so the numbers do match. Just for comparison, my coffee pot has an initial draw of 1400 watts. The AC-180 had no problems with the start up draw from the sump pump. The Bluetti AC-180 cannot survive immersion in water and needs to be kept in a clean dry environment. So, if I had to use the AC-180, I would be using a long extension cord, probably a fifty-foot cord which I do have. The sump pump has a 10-foot electric cord, so I would be using some waterproof connection between the two of them. (Just so that I have mentioned it, Bluetti does offer several solar generators that are IP65 rated such as the AC60 or the AL-240.)My point is that this is a quality sump pump that will work for you, provided you have electrical power. It is worth five stars. From having used it in my testing, it seems to be well made and solid. Once the water level turns on its switch, it does not hesitate as you receive an immediate intense flow of outbound water. For most people, plan A for using this unit is the household electric grid provided electric power. I am suggesting that you have a plan B, for when the grid power is not there.

I just had to rework my basement sump pump system. My old pump had the water level switch go out and I was also having issues with backflow. So I got a backflow preventer valve and a replacement sump pump, blew out my drain lines and just got it all installed.We've had quite a bit of rain recently, 9 inches in the past 2 weeks and even my normally dry basement is getting some water in, although the back flow preventer valve helps quite a bit. As much of my water was coming in as overflow from my old sump pump well, the combo of this pump and the back flow valve has remedied my basement water issue. The pump runs pretty quite, and I like that the water inlet is about 1 inch above floor level and not on the bottom of the pump. The oversized float style water sensor switch is a nice design element, but does make the pump footprint a bit bigger than a normal sump pump.So far its working well. I took 1 star off because the metal handle on the top is really a poor design and without the longer piece the smaller handle does not work.
