A Model-By-Model Review of the Four Major Sump Pump Models
Improper sump pump installations can lead to moisture, odors, and noise coming from the sump pit. By selecting a sump pump that is reliable, quiet, long-lasting, and strong enough to keep your basement dry, you can be sure that your space is best protected from groundwater seepage.
With so many basements flooding these days, many different models of sump pump systems have been designed to handle this. The most common of these sump pumps are pedestal sump pumps, submersible pumps, water-powered sump pumps, and “floor-sucker” models.
We have carefully researched each sump pump model available on the market to determine which model we’re willing to stand by when we waterproof your basement.
Below, we’ve provided a review of all four major sump pump designs, including the strengths and weaknesses of each one. Read on to see how we select our system, and which one is right for you.

Pedestal Sump Pump Systems
Pedestal Sump Pumps are pumps that are not meant to be submerged in water. These pumps are mounted above the water line, with a long line from the float switch down into the pit.
Pedestal sump pumps are often mass-produced designs with a double engine casing around the engine that retains more heat than single casings.
This — combined with the fact that pedestal pumps cannot be immersed in cooling water — tends to make the engines overheat and break down prematurely.
Pedestal sump pumps are raised high out of the water, and they generate a great deal of vibration when they’re running.
These vibrations cause the sump pump to “wander” in the pit. If the pump drifts too close to the edges, the switch that turns the pump on and off may be jammed in an ON or OFF position, leading to problems. Additionally, the long line between the switch and pump clogs easily.
Pedestal sump pumps tend to be less-expensive sump pumps that have been mass produced. Often, they are made out of plastic instead of cast-iron.
While much higher in capacity than other models, these low-end pumps are not always strong enough to keep up with the water flowing into the sump pit.
Because a pedestal sump pump cannot be submerged in the water, they cannot be installed within the sump pump liner.
Because of this, they must run while suspended in the air in your basement. They’re excessively loud, and the open sump pit below them will collect debris, while allowing odors and humidity into your basement.
Pedestal sump pumps are more expensive than water-powered sump pumps and “floor sucker” models, but generally less expensive than submersible sump pumps.
However, because they break down so chronically, you can expect a submersible sump pump, and even a water-powered sump pump, to far outlast a pedestal pump. This makes them a poorer value for your money.
- Higher Capacity — Pedestal sump pumps are one of the higher-capacity sump pumps available on the market. They’re more able than some models to keep up with heavy volumes of water.
- Frequent Malfunctions — These low-end pumps are notorious for early burnout. Pedestal pumps also “wander” in their sump pits and can jam their sump pump switch on the side, forcing it to stay on or off.
- Noisy Operation — Because the motor is out of the sump pit, the noise from the pump cannot be muffled by a lid. Pedestal pumps usually stand in open pits, which let in odors and humidity.
Submersible Sump Pump Systems
Submersible Sump Pumps are installed in a sump pit and are meant to be immersed in water when operating. The water cools the unit to help prevent burnouts, while the sump pit can be covered for noise reduction.
Submersible sump pumps come in a very wide range of quality and designs. However, submersible models are generally of a higher quality when compared to other models of sump pump,. They naturally disperse heat from the pump into the water around them.
For the longest life, find a submersible sump with a cast-iron center and an appropriately sized liner.
Submersible sump pumps often outlive several generations of pedestal sump pumps. When properly maintained, they can last for many years without failure.
A reliable submersible pump should have no screen on the intake and should include a plastic liner with a stand that keeps it off the bottom, where any debris will settle.
Submersible sump pumps are generally far more heavy-duty and higher-capacity than comparable other sump pump designs.
It’s important to note that while submersible pumps are more powerful, the sump pump should be appropriately powerful for the job. If it’s too powerful, it will turn on and off repeatedly. If it’s not powerful enough, your basement will flood.
All sump pumps make at least a little noise, but submersible pumps are the quietest pumps available.
The quietest submersible sump pumps include a liner with an airtight lid, as well as rubber grommets around pipe and wire entrances. The discharge lines should also be large and straight, so that the sump pump isn’t trying to noisily force water through narrow pipes.
The price tag for a single submersible sump pump is higher than other models on the market.
However, a good argument can be made for the quality and long life of submersible pumps. A submersible pump will outlast all other designs, bringing you the best value for your investment.
- High Capacity Operation — Submersible sump pumps are high-capacity units that can keep any basement or crawl space dry. When combined with a battery backup submersible pump, they provide the best protection of available models.
- Long Lifespan — Because the cast iron housing around the motor can disperse heat naturally into the water, these self-cooling pumps are long-lasting and reliable protection for your home.
- Initial Investment — While a submersible sump pump will outlast several generations of similar pumps, they cost slightly more on their initial investment than comparable alternatives.
Water-Powered Sump Pumps
Water-Powered Sump Pumps are installed above the pump pit and are powered by your water supply instead of electricity. These systems use your town water supply and depend on your home's water pressure for pumping capacity.
Water-powered sump pumps are a long-lasting sump pump model that outlasts pedestal pumps and “floor sucker” models by a large margin.
When used as a backup system for a submersible sump pump, water-powered sump pumps can be an appropriate part of a basement waterproofing system.
While water-powered pumps can last for a very long time, they are one of the less-reliable options for basement waterproofing.
Water-powered sump pumps rely on your home’s water pressure to maintain proper operation. If your home has low water pressure, then your pump may not operate at full strength, resulting in a wet basement.
Water-powered sump pumps are, unfortunately, among the lowest-capacity sump systems on the market.
Water-powered pumps depend on your home’s water pressure to run. They discharge 3-5 gallons of usable water from your plumbing for every gallon of groundwater pumped out of your house, and during heavy flooding, they are often overwhelmed, resulting in a flood.
Water-powered sump pumps are among the quietest sump pumps on the market- especially when compared to noisy “floor-suckers” and pedestal sump pumps.
To ensure the maximum noise reduction, make sure the discharge and intake lines are large enough for the water being pumped through. An airtight lid should also be installed around the intake line on the sump pump lid.
A water-powered sump pump system is longer-lasting than “floor sucker” pumps as well as pedestal sump pumps and shorter-lived than submersible pumps.
At a lower cost, they are a better value than many sump pump models. They use no electricity — however, they do use 3-5 gallons of water for each gallon of groundwater discharged.
- Runs Without Electricity— Water-powered sump pumps operate by using your local water supply to help discharge water, allowing them to run through many power outages. 3-5 gallons will be used for each gallon of groundwater discharged.
- Long Lifespan– These pumps are long-lasting, durable systems that should continue operation for many years.
- Low Pumping Capacity— Unfortunately, water-powered sump pumps run at very low capacity. Heavy rains and water volumes will quickly overwhelm these systems.
- Requires High Home Water Pressure— If your home has low water pressure, it will greatly affect how useful these pumps are. If you experience a temporary loss of water pressure, they may fail to operate entirely.
"Floor Sucker" Sump Pump Systems
"Floor Sucker" Sump Pumps will only switch on after the basement has already flooded. They're often used by contractors and many homeowners as an emergency pump to suck the water off of the floor before installing a better waterproofing system.
A “floor sucker” sump pump can last for several years, but only because they only run when your basement is flooding at its worst.
A floor sucker cannot compete with a normal pump system when it comes to actual hours of operation, and they should not be counted on to last during heavy volumes, when they’re needed most.
A floor sucker sump pump will only turn on when the basement floods, making them the least reliable way to keep your basement dry of all models.
Even when a “floor sucker” is on and operating, it will not remove all water in your basement. A 1/8″ layer of water, at least, will always remain after the pump completes its operation.
“Floor Suckers” are not known to be powerful, high-capacity sump pump systems.
During significant floods and heavy rains, these pumps are likely to be overwhelmed by flooding water, which will rise faster than these pumps can remove it.
“Floor Suckers” are the noisiest sump pumps of them all — even louder than pedestal pumps.
These pumps operate directly on your basement floor, discharging through a common garden hose. The literally suck the water from the floor, creating noise from the motor, suction, and through the discharge line (garden hose).
“Floor Suckers” the least expensive sump pumps on the market. They install with no need to create a sump pit or drainage channel, making them fast and inexpensive to install.
However, if you’re paying to keep your basement dry, you’ve come to the wrong place. These are notoriously low-end pumps that can’t keep up with heavy rains, and they will never last long.
- Requires No Sump Pit or French Drain — “Floor Suckers” sit directly on the basement floor. There’s no need to install a perimeter French drain or sump pit.
- No Installation Time — These pumps are ready for use immediately, making them a good option for emergency use, or to clear out flooded waters before installing a different system.
- Does Not Stop Flooding — Your basement must flood with more than 1/8″ of water before this pump begins operation. If you’re paying to dry your basement, this is not a solution.
- Loud & Low Capacity — These pumps are low-end models that will not be able to keep up with heavy floods. The pump operation, sucking sounds, and discharge line will all contribute to significant noise during operation.
