So far so good. Bought this to empty my hot tub every 4 months for cleaning. 440-gallon hottub was emptied in about 30 minutes. Not noisy. Came with garden hose adapter so it was plug and play for me.

Getting us through hurricane Matthew southeast of Raleigh, NC, as the basement sump pump couldn’t keep up with hours of 6″ per hour rainfall. Deployed the pump and have been lowering the water 1″ per hour with about a 10′ lift (1200 gal/hr). The generator standing by just in case but this little guy saved the furnace and hot water heater!

The WAYNE CDU980E sump pump is the best sump pump anyone can settle for as it comes with a 3/4HP motor while its body construction features a cast iron and stainless steel coating as well as a vertical float switch.

There would be nothing to get worried about once this sump pump gets mounted in any sump pit and its water cord is about eight feet long but has water and wear-resistant design which makes sure it doesn’t break down despite being submerged for long hours.

Even if you are working on weep holes, there is still nothing to get worried about as this sump pump comes with a top suction power which helps in eliminating clogging and getting rid of the airlock.

I had a flooded basement and December from tons of rain. I’m still cleaning up from that but now my son put in the sump pump. We had a bunch of rain again last week and it works perfectly… Amazon thank you for carrying these things That are easy for us to find and use, and thank you to people who put in the reviews because it helped make me make my decision. That’s why I’m doing it now. You will not regret this one, I promise. I had a video but I don’t know how to post it.

Serious groundwater issues in our basement this past spring. Old 150 year old house where part of the basement is dirt and part is concrete. We got so much rain this past spring, the water table in our area was all the way to the surface so when it rained, it just rose above the dirt floor. Had persistent 3″+ water on that side. Was able to self-install this pump in a basin and it worked and worked and worked! There were times where it just pumped non-stop. Once I finally got ahead of the groundwater, it has done its job great. I’m not sure how many years of service I’ll get out of it, but the price is great, it was quiet, and pumped great.

3. Professional EZ Travel Collection Drain Pump

The next sump pump that we want to review is the Professional EZ Travel Collection Drain Pump which is designed to have everything that you need in order to deliver an amazing performance.

This sump pump is also easy to operate as all that it requires is connecting its twenty-five feet drain hose to the pump and dropping it inside the pool or tub and it would get its job done and if you are into the maintenance of pools or tubs then you would love this pumps folding feet design which guarantees low profile suction.

The flow rate generated from this pump’s 1/2HP motor would provide up to 3700GPH which makes this sump pump the best when working on hot tubs, spas, ponds, swimming pools and even in basements and its lightweight and comfortable design are features that users are always impressed with when talking about the Professional EZ Travel Collection drain pump as it aids transportation from one site to another.


  • The lightweight design makes it easy to carry this pump from one place to another
  • Best used for spas, tubs, pools and even basements
  • More water would be drained from the bottom of any pool thanks to its folding feet design


  • Doesn’t have a manufacturers warranty
  • Comes with no power switch as well

Bought it to drain my 10,000 gallons in-ground pool. Worked PERFECT! Zero issues. The ONLY drawback, which has been the case with most pumps. Once you get to the last gallons, the rise to ground level is tough. I rigged a rack to keep the hose vertical and it worked fine.


This pump is quiet, and pumps out serious water! I drained my 25,000-gallon swimming pool in about 24 hours with this guy! Drained it all the way down to about 1″ of water left. I Highly recommend this pump!

4. Flotec FPPM3600D-01/09 1/3 HP Pedestal Sump Pump

Another best submersible pump is the Flotec FPPM3600D-01 pedestal sump pump which is specially designed for use on broader and twelve-inch basins. Even though this sump pump is mostly considered to be a replacement pump, it can still be used as a new installation and having a vertical float switch simply means that this sump pump would only get into action when it is needed or when it is called upon.

However, the only downside of this pump is its six-foot power cord which might cause users to need an extension.

The reason why users love its vertical float switch is that it ensures that excess water gets eliminated before this machine gets shuts down and you can rely on this sump pump for as long as twenty years thanks to its pedestal and thermoplastic design.

The reason why this sump pump is also used as a replacement pump is that it can be mounted easily on other brands and a new hole in any foundation would not be necessary thanks to its 12-inch basin diameter.


  • Lightweight design boosts ease of use
  • Comes with a vertical float switch which gets rid of excess water
  • Can be installed new or used as a replacement pump


  • Makes noise during operation
  • Comes with a short power cord

I needed a pedestal pump to empty my sump about once every day or so. This was the ideal pump; easy to install and does the job perfectly. Only time will tell its reliability and lifespan. I plan on “testing” it once a month to make sure it does not seize up due to sitting without use (should that ever occur). I am totally satisfied with this purchase.

Amazon Customer

Installed for a few days now, so far so good. Very quiet, float works wonderfully. Our first experience with a pedestal pump. Pleased, hoping for longevity as others have been happy with it’s durability.

5. Liberty Pumps 404 1/3 HP, 115V Residential Drain Pump

The Liberty 404 sump pump is another best-rated sump pump that buyers are bound to encounter when searching for the best sump pump today and this sump pump has a compact design with two housings so it can be used for testing float or cleaning purposes without having to disconnect this sump pump when it is already connected.

We refer to this sump pump as a small but mighty sump because of its motor’s ability to generate up to 2200GPH which makes it a good option for use in crawl spaces.

Not only is this sump pump used for crawl spaces but it can also be used in laundry rooms, bar sinks and other low-level drain areas.

The main reason behind the design of the Liberty 404 sump pump is for it to be used in compact areas so that users would also have the freedom to be able to install fixtures especially in areas where there are no gravity drain lines.

Safety measures need to be taken when working with this sump pump as its grounded three-prong cord needs to be connected to a GCFI in order to eliminate the possibility of an electrical shock.


  • Regardless of location or size, this sump pump would be installed with ease
  • Comes with side and front inlet options
  • Runs a quiet operation that makes it suitable for various purposes


  • Its power cord has no waterproof design
  • Its GPH rating is lower than most sump pumps on the market

This thing is too cool. Pumps water like a demon. It is overpowered to drain a whirlpool tub … it takes 10-20 seconds to fill and 5 seconds to eject. As a result, it goes on and off more than a dozen times while my 90-gallon whirlpool tub drains. I am concerned it may fail prematurely due to the rapid start/stop. Since we only use it 1-3 times per week, maybe it won’t be a problem.


Works like a charm and has a 2″NPS port to meet the code for a laundry discharge. Intake (side port) and vent are interchangeable. Nice and quiet. Sized well for my new HE washer.

Great pump. Was delivered fast and packaged well. I’m not a plumber by any means. A combo of the included instructions and a 5 minute YouTube video gave me all the knowledge I needed.


We had a flood in our basement on 3/19/20 and our pump was not keeping up with all the water coming in. Our neighbor brought over his extra pump which is the same pump that we bought off of Amazon (Zoeller). It went right to work and pumped out water at a faster rate than ours. 5 minutes after he hooked up his, ours quit! It is a bit noisy when it runs but it doesn’t stay on very long at all. We bought the same one that he let us use and we are happy. My husband installed it himself and said that it was easy.

7. Liberty, SJ10, Sump Pump, Water Powered

When working with sump pumps, one thing that you must have is a backup plan and it is quite clear that the popular backup plan we have today is the electric backup plan but looking at the water backup plan, you would realize that this form of sump pump doesn’t need the power to function.

The best water backup plan that anyone can settle for is the Liberty Pumps SJ10 whose installation should be done by a professional plumber so as to ensure that the drain and water pipes are well connected.

You will be surprised that this sump pump would function without power and as far as there is water service running in your home, this water pump would function effectively and efficiently.

What a great find. I heard about water driven back up sumps when in Ohio last winter. If you travel a lot and you have valuables in your basement subject to an overflow of water from your sump, then this is a must. It is gravity fed from your main water line, so even when your house power shoots craps for longer than 8 hours, this will work (as compared to a battery-driven back up where the battery will just run out of juice and your basement will flood). I would buy another in a New York minute. Unless you are a plumber or incredibly handy, I would highly recommend a professional install due to the cut into your main water line.


So easy to hook up. I suggest u get a slotted sump cover. Most install pics I’ve seen have no cover installed since the pump sits over the cover it makes it difficult to install on a standard cover. Just did my first test by filling up the basin and wow is this pump quiet I hardly realized it was pumping till I saw it cleared all the water in my basin. Also be sure to install a backflow preventer my local plumbing inspector recommended the watts 9d and it seems to be working great.

8. WAYNE ESP25 12 Volt Battery Back-Up Sump Pump System

The WAYNE ESP25 is the best option anyone who is in need of a battery backup sump pump can go for and this is actually the second product from the WAYNE brand to make it to this review.

This is simply the best as it comes with every necessary feature that you can think of for it to function properly including an alarm but the only thing that needs to be purchased separately is a battery.

It is also recommended that when buying the battery, the WAYNE WSB1275 battery should be bought as it offers up to eight hours of run time and comes already charged.

Coming already charged means this battery can start working inside the sump pump immediately it arrives and the alarm of the sump pump rings when this backup starts operating.

This alarm system also informs you when the battery is running low and this backup pump comes with a two-year limited warranty. However, the battery comes with a one year warranty as well.


  • Easily installed on an already existing system
  • Its alarm helps in notifying users on operation and battery status
  • Comes with a ten-foot head that offers space for emergency situations


  • Doesn’t come with a battery

The installation of the unit was not difficult. After hooking up the battery, I tested the unit by lifting the float switch. The pump started up and the alarm sounded. After releasing the float switch, the pump went off after a short time. All returned to normal (the alarm went off) and the control panel properly indicated the battery was being charged. I am very satisfied with the operation of the system.

Amazon Customer

Thankfully, we have yet to encounter a scenario where the backup pump was required. We have had the unit for a couple of months so far. Installation and instructions were straightforward and not difficult. Battery chirps if the pump is activated. The pump isn’t the same output as the regular, but it clears our sump hole quickly enough to provide confidence.

9. Wayne WSS30VN Upgraded Combination Battery Back-Up System

You would actually want to make use of the best sump pump in protecting your basements and the only answer that you have is the WAYNE WSS30VN sump pump which is actually the combination of a twelve-volt battery pack and 1/2HP primary pump.

Works perfect. I learned a few things.
1) you have to use a check valve for both the main and the backup pumps (kind of a no-duh when you think about it). The attached picture shows the installation of the pumps.
2) there are alternatives to the Wayne battery. I was very concerned about what battery to use. The Wayne battery is expensive and I had seen in other forums that you just need a deep cycle marine battery. I found a Duracell SL127MDC at batteries plus that fit and works just fine – i think it was about $89.


So I originally wrote a review after the installation of this sump pump in which I gave it 4 stars. I decided to write another one after I saw this sump pump in action. About a week after installation, a severe thunderstorm knocked out power in my area. We were without power for about a day and I was worried that my basement could flood due to the heavy rains. Well I worried for nothing. Within 20 minutes after the power went out, the backup sump pump kicked in. The charger embedded in the battery box would beep and immediately the DC sump pump would switch on and evacuate the water. It did this regularly every 17 minutes for the entire 26 hours we were without power. We got this sump pump just in time and it worked exactly as it was supposed to.

This is a great pump and basin setup for a crawl space. Installation was simple and testing showed that the sensor worked perfectly. I drilled another row of holes in the basin to increase volume and plumbed a basic 1.5″ pvc output tube to the watershed. The tubing provided was not useful for anything and was discarded. The pump is very powerful and emptied the basin in a few seconds. The cycling was perfect in that the basin needed to be more than half full before the pump activated.

This pump isn’t cheap, but you do get what you pay for. It is so quiet that you honestly will doubt that it is running and fill the pump well with water just to make sure it is functioning. It has worked flawlessly since we got it 5 months ago. It kicks on 8 to 9 times a day as the need arises sometimes more if there is a lot of rain. If your not handy with concrete work I wouldn’t suggest trying to put it in yourself. Couldn’t be happier with this product.
