Features

  • Kindly Tip 1When you start use the pump you must be submerged into the water at a slight angle to allowthe remaining air to escape.
  • Kindly Tip 2The device is not suitable for continuous operation (e.g.as recirculation pump for ponds).This type of use will substantially shorten the pump's life expectancy.
  • 1HP High PowerProstormer Sump Pump uses 1HP power, which is more efficient than ordinary 3/4HP sump pump; Max 3500GPH rating tackles any draining job at a fraction of the time.
  • Multi Outlet Sizes3 different diameters outlets (1 inch ,1-1/4 inch, 1-1/2 inch) to adapte for different size hoses as needed according to the flow rate. The bigger the flow is, the wider the outlet should be.
  • Manual ModeSet the switch to the MANUAL positon the pump will now not automatically switch off but carry out pumping, even if theremaining water level is reached and the pump runs dry. You should cut off the power immediately to prevent the coil from getting burned.
  • Automated ModeSet the switch to the AUTO position. Once you have plugged the device into the socket, the pump will switch on automatically when the water exceeds the start-level and switch off when the stop-level hasbeen obtained.this means that the pump can be left on at all times and will keep the waterin a cellar or boat, for example, at the required level.bear in mind that this pump is notdesigned to be used continuously, it must be switched off at regular intervals.

    • Update 1 year later...Works like a champ!!
Style: 1HP
Update 1 year later... I have used this pump several times over the winter to drain water off my pool cover. It has worked flawlessly. This is hands down the best pump I've owned! Once you figure out your hose size connection, you're golden. I purchased a Superior Pump heavy duty 1.5" 25' lay flat discharge hose kit with 1.25, 1.5 discharge size. Clamp with a hose clamp and let it rip. I haven't had any debris that the pump will not mulch and suck through yet with no damage to the pump. I am particularly fond of the auto feature that shuts the pump off when the water level is too low to pump. I can walk away from it and forget about it. I highly recommend!! My pump showed up today, and I put it straight to work. Instructions weren't terrible, but could be a little clearer. I figured out the initial startup and air purge without any issues. It's a hefty little sucker, and for being plastic appears quite sturdy and we'll built. The two adapters that come with it seem thick and sturdy as well. If you're looking to hook up a yard hose to it then you're in luck. It will screw right on there with the supplied reducer. I bought it because of the 1 hp motor, and high flow rate, and I wanted to use a 1 1/2 inch hose. Unfortunately, the adapters that came with it are only reducers fro 1 12 inches. Now granted, the largest diameter reducer is 1 1/4 inches, so I cut off the excess smaller end and the hose fit with a hose clamp with some minor leakage. It did not appear to affect the pumping suction though. I will go purchase a threaded coupler from the hardware store and use the 1 1/2 inch adapter that I already have. Not a big deal really. I bought it to finish draining my pool for a deep clean. My old Wayne pump that I've had for years and rebuilt a couple of times finally decided to croak for good leaving about 2 ft of water in a 24 ft round pool. I was about to spend about 4 times more than this pump costs, and I thought for the price, why not? So I hooked up the hose, purged the air, and plugged it up. This sucker is a hoss!! It completely filled the 1.5 inch hose and started throwing some water! It drained the remaining water in under an hr. One note if you're not paying attention to detail...it only drains down to 3/4 inch. If you're looking for lower than that, look elsewhere. It was perfect for my needs. On a positive note, it will suck debris up to 1/2 inch, and I can tell you it does it effectively without any snafu's! Oh yeah, another plus is that it's very quiet which is nice. The only real downside that I see to this pump is the topside discharge. Once your water gets low enough, the weight of the hose will tip it over. So I had to babysit it for a bit close to the end. I believe that I will solve this by making a hard vertical pvc pipe with a 90 at the top with an extension to attach the hose to. It will be a fairly cheap fix and work well I think. You could adapt that setup to any situation that you have. Overall, I would highly recommend this pump after first use!! It performed flawlessly! The price point is unbeatable for a 3500 gal/ hr pump and a 1 hp motor. I will update after I've used it a few more times, but for now...5 stars!! ... show more

    • Great workhorse of a pump for accumulating rainwater!
Style: 1HP
Purchased this pump to manage standing water in backyard during Southern California Winter 2024. This unit worked great in auto-shutoff mode and I was able to leave it plugged in for over a week to remove accumulated water. I used this inside a 12" catch basin connected to a 75-foot 2 1/4" corrugated pipe from Harbor Freight to push rainwater to the street. The only concern with this unit is it has a taller intake so you won't be able to suck up all the water...you will leave about 1/2" before too much air cuts off the suction. PROS - Super powerful 1hp motor that easily moved water from 13" catch basin through 75' (yes, feet) of collapsible tubing on mostly flat ground. - Auto-shutoff mode worked very well when leaving unit plugged in for over a week during California Winter 2024 storms. - Has adjustable internal float switch where you can increase the depth of water when using auto-shutoff mode. - Comes with lots of fitting attachments to meet different applications. CONS - Has minimum clearance of about 1/2" and will leave about 1/2" of water regardless of auto or manual mode. I had hoped for only about 1/4", but this is not a big deal. - So powerful, the unit jerks a little when turning on in auto mode. For my application, I could have gone with smaller horsepower, but the auto-shutoff mode worked great. ... show more

    • A little fiddly, but worked all spring to drain my yard
Style: 1HP
Worked to drain a huge pond that forms in my yard whenever it rains. It would drain an area about 15x15, maybe 6-8 inches deep, in about 2 hours. At one point, it did get clogged and I took it apart to free the float, but given it pumped out a LOT of dirt and leaves, I was pretty happy with it. I had to put it on a flat pan in the deepest part of the yard, because it didn't have enough clearance not to immediately clog on the bare ground, but the pan method worked well. You can set it to run constantly (and burn up when it's dry) or turn off when the float gets low. It was a little hard to figure out which way was which, as it's a raised bump on the plastic which was hard to read. The hose comes out straight up, which is fine for a well or deep pond, but i had to muddle together an elbow to connect my hose, otherwise it just folded over and cut off flow. It would be great if it came with an elbow piece along with the other two attachments. It's a little hard to get it going, as dropping it straight in will keep air inside, and it won't start. But with a bit of practice, I figured out how to angle it so all the air came out as it entered the water. Hope it works as well for next year. ... show more

The media could not be loaded. I have had this pump for less than a year and up until recently it had been performing great. I have only used it to pump my hot tub out twice and a neighbor's tiny kid pool out once. 3 days ago we were hit my a huge storm that put down a TON of rain and everyone's window wells were filling up with water. I had water 8 inches up on one of my basement windows as well as my next door neighbor. We grabbed this pump to help us bail water put of our window wells and in the middle of all this it quit working reliably. It let me down when I needed it the most. We ended up having to toss it aside and just bucket out the water. I works for a while then it slows way down to where water is hardly coming out as if it's just chu chu chugging. Then finally it will slowly pick up the pace and and within less than a minute it slows way back down to barely any output and chuggs for a bit then will speed back up. I tried recreating it using a bucket in this video and and it shows it chugging and then finally ramping back up. Then it almost tipped and sprayed me. Sometimes when I trial it in a bucket, the bucket will be almost all the way full before it starts to even put out water. Kind of frustrating in the middle of a flash flood that was basically flooding our entire neighborhood. ... show more

    • It works well.
Style: 1/2HP
The last 2 pumps we had were loud and we had to nudge it to make it work. This one turns on and off by itself, I love it. No more running to the basement when it rains.
