Best Submersible Sump Pump

The best submersible sump pump to choose is one that’s sized correctly for your basement and water table – and still works within your budget. Read my submersible sump pump reviews to help you make the right choice.

And you can check out my #1 recommended sump pump for homeowners: the Zoeller M53 Mighty Mate on Amazon.

Submersible Sump Pump Reviews

The most common type of submersible sump pump sold to homeowners is the 1/3  HP (horsepower) size. A 1/3 HP submersible sump pump is a common sweet-spot for homeowners when they're choosing between power and value for the average sized home.

I highly recommend the Zoeller M53 Mighty-mate Submersible Sump Pump with 1/3HP, on Amazon, as the best submersible sump pump value for homeowners.  

Here’s why: the 1/3HP motor size is the right power size for the average sized home & it makes little to no noise when it’s running. And this Zoeller M53 sump pump has a high quality cast iron switch case, motor and pump housing. 

The Zoeller M53 will pump a maximum of 2,580 gallons per hour. It’s a workhorse!

Check Amazon’s price on the Zoeller M53 Mighty-mate.

Readers of my submersible sump pump reviews report that they really appreciate the quiet operation of this submersible pump - especially when they're trying to sleep at night. (If you've ever been kept awake by a loud sump pump, you know what I mean!)

1/2 HP Sump Pump - Submersible Sump Pump Reviews

Wayne Sump Pump CDU800

But if you have a larger home or higher water table or your existing 1/3 HP sump pump is not doing the job of keeping your basement dry, you probably want to move up to the 1/2 HP submersible sump pump. So you should consider the Wayne sump pump CDU800 model:

And you can see my top recommended 1/2 horsepower submersible sump pump: the Wayne CDU800 sump pump on Amazon.

It has a strong 1/2 HP motor, cast iron construction for longer life and a ceramic mechanical seal for working in demanding water situations. It offers a maximum flow rate of 4,200 gallons per hour GPH! The Wayne CDU800 also has an integrated vertical float switch and a 3 year warranty.

A 1/2 HP sump pump installed in your basement or crawl space will usually give you about 35% more power than a 1/3HP unit.

And if you have a higher vertical lift to deal with - say more than 35ft -you'll probably do better to invest in the larger 1/2 HP sump pump. The higher 1/2 HP sump pump power will be able to overcome the loss of power and GPM you can experience when you have a higher vertical lift. 

Submersible Sump Pump Reviews: 3/4 HP Sump Pump

If you're replacing your existing 3/4 HP sump pump you should stick with the same HP for your replacement submersible sump pump. As long as your existing pump was doing the job, your sump pump was sized correctly for your home and you should stick with the same 3/4 HP rating.

If you have a higher water table, larger basement or high vertical lift, you'll want to think about a 3/4 hp sump pump.

I recommend the Wayne CDU980E on Amazon if you need a 3/4 HP sump pump.

Why? It's constructed with heavy-duty cast iron base and rust-free stainless steel motor house, for a long working life. The 3/4 HP can give you a max flow rate of 4,600 GPH! The Wayne CDU980E has an integrated vertical float switch & a generous 5 year warranty.

Check Amazon's price on the Wayne CDU980E.

I wanted to show you how to determine the HP on your existing submersible sump pump, by checking the information on your sump pump service plate.Check the HP rating on your existing submersible sump pump.

Are you reading these submersible sump pump reviews but you're not sure what HP you have in your current sump pump?

Every submersible sump pump has a data plate or service plate attached to it - on the motor.  So, you just need to pull out your existing sump pump and find the HP rating on your existing sump pump.

And if you've experienced submersible sump pump failure in your basement, it's always good to know what damages are covered under FEMA flood insurance. You can read more here.


Let’s talk about how to determine the right size for your new submersible sump pump and what features you should look for.

Are you replacing an existing sump pump? Was it doing a good job of keeping your basement or crawl space dry before it wore out? If your existing sump pump was doing a good job, it’s easy to replace it with the correct submersible sump pump size.  Just look on the service plate next to your existing sump pump motor to find the horsepower rating (HP).  And match the existing horsepower rating to your new submersible sump pump horse power rating.

Pedestal or Submersible Sump Pump?

You may be wondering, when you're considering a pedestal or submersible sump pump, "which is right for me?"

Well, if you want a sump pump with the most economical price, I would recommend a pedestal sump pump. Between pedestal or submersible sump pumps, on average, pedestal models are more competitively priced.

And you can see my top pedestal sump pump recommendation: the Flotec 1/3HP pedestal pump on Amazon.

Also, if you don't have  a sump pit or sump basin already dug in your basement, you can just install a pedestal sump pump on your floor surface - without the extra expense of breaking concrete & digging a sump pit. This will save you money.

I can recommend the Flotec FPPM3600D 1/3 HP Pedestal Sump Pump on Amazon.

This pedestal style sump pump will pump up to 3,480 gallons per hour (GPH), is designed with a non-clogging impeller and has a top screen inlet with 1.25” discharge. The Flotec FPPM3600D has both thermoplastic and cast iron construction with an 6 foot, 3 prong cord/plug.

But, if you already have a sump basin installed in your basement floor, and sump pump operating noise is a concern for you, I'd recommend a submersible sump pump.

You see, since a submersible sump pump is lowered into your sump basin, below your floor level, the operating sound is muffled. In fact, you may not even hear the sump pump running.

And if you already have a sump pump pit, you won't have to hire a contractor to come in & dig one for you - which is a big savings!

These are a few important considerations to take in account when you're choosing between a pedestal or submersible sump pump.

Do you need a radon sump pump cover?

Pedestal or Submersible Sump Pump ?


Should you use a radon sump pump cover on your submersible sump pump?

After you've installed your best submersible sump pump, you'll want to create a sealed sump pit using a radon sump pump cover.

A sump pump radon cover will help keep dangerous radon gas from entering your basement. As you know, radon gas is invisible and odorless, but a radon sump cover, when it's properly sealed, will lessen the amount of gas that will seep into your basement.

And I always tell my readers that its a good idea to add a sealed sump pump cover to the top of their sump pit even if they don't have radon issues. That's because a sump pump cover seal also keeps nasty odors, from the standing pit water, out of your basement too. It's not uncommon to have a rotten egg  or musty smell come from your sump pit water. And a sealed sump pump pit cover will help eliminate that problem too.

I highly recommend the Original Radon Sump Dome on Amazon because its Made in the USA of heavy-duty polyethylene structural foam plastic with stainless steel bolts. It will work with any sump basins with up to a 24" opening diameter. It's built tough with 1000 pound max weight capacity.

The Original Radon Sump Dome will help keep radon and bad sump odors out of your basement & home.

Check Amazon's price on the Original Radon Sump Dome.

And, of course, having a tight sump pump well cover will keep children or pets from investigating your sump pump well. Children and pets are naturally curious about wells, and that could lead to an injury. Or sump pump damage. A radon sump pump cover is an economical safety device that I highly recommend.

Here's a short video describing what radon gas is, how its dangerous and why you need radon sump pump cover on your submersible pump:


How does a submersible sump pump work?

I’m often asked: How does a submersible sump pump work? So I’ll try to quickly and easily explain exactly how submersible sump pumps work:

A submersible sump pump is installed inside a sturdy sump pump basin, within a basement sump pump pit. Submersible sump pumps are centrifugal pumps that are equipped with an electrical motor that’s plugged into a wall outlet.

here's how a submersible sump pump works

When water rises in your sump basin, the float on the sump pump rises, which activates the sump pump switch. Then the submersible sump pump motor turns on and begins spinning the internal impeller. The impeller then forces the excess water through your discharge pipe – and out of your basement.  And it’s important to note that your discharge pipe should have a one-way check valve to make sure the water doesn’t come back into your basement.

Advice on Submersible Sump Pump Placement

Are you noticing a little water in your basement, but don't currently have a sump pump? You might want to think about installing the best submersible sump pump system to get rid of water that collects in your basement. And protect yourself from a future flood.

I wanted to share my sump pump placement tips to make the job easy.

The first thing you want to think about, before you start digging, is your sump pump placement. You should dig your sump pit in the lowest part of your basement. Usually were the water has been collecting.

If it's obvious where the low lying area of your basement is, it's easy to see where your sump pump should be placed. Or you can use a level to find the right sump pump placement spot.

Once you've found the low spot in your basement, you'll want to place your sump pump near an outlying wall. I advise readers that the best sump pump placement is about ten inches from the outside wall. This way, it will be easier to install you discharge lines. And, of course, your sump pump will be placed close to an electrical outlet.

And remember, before you do any digging double-check the location of your power lines and sewer pipes. Seriously. They might be sitting below your foundation, and when you break through your basement floor, you don't want to break any pipes. That's a huge, messy problem you just don't to have to deal with. So make sure you know where your electrical lines and sewer pipes are before you break ground.

And don't forget, you might need a permit, in your area, to install a sump pit in your basement. And you'll want to see if there are any codes you need to meet, during this construction.

With the right sump pump placement spot, the installation of your best submersible sump pump will go a heck of a lot easier.

Non Submersible Sump Pump vs the Best Submersible Sump Pump

Yes, there are non submersible sump pump models on the market and they’re called pedestal sump pumps. Pedestal style sump pumps are an older style of pump and they’re non submersible sump pumps: they’re installed above the sump pit. They’re usually placed on your basement floor.

I can recommend the Flotec FPPM3600D 1/3 HP Pedestal Sump Pump on Amazon.

This pedestal style sump pump will pump up to 3,480 gallons per hour (GPH), is designed with a non-clogging impeller and has a top screen inlet with 1.25” discharge. The Flotec FPPM3600D has both thermoplastic and cast iron construction with an 6 foot, 3 prong cord/plug.

And you can check Amazon’s price on the Flotec FPPM3600D Pedestal Sump Pump.

Yes, generally speaking, pedestal sump pumps are less expensive than submersible pumps. But, because pedestal pumps are non submersible sump pumps, and there is no basin to buffer the noise, they are louder when they’re running.

And another benefit to a non submersible sum pump is that they’re easy to install and replace. You don’t have to dig up part of you sump pit in order to put it in place.
