Whether it’s a spare bedroom or game room, the last thing you want to deal with down there is the loud clanging of a sump pump!

Do You Really Need a Sump Pump?

To put it simply: Yes! If you have a basement, a sump pump is an absolute necessity.

After a heavy rain, water flows to the lowest point possible. On slab or raised foundations, that’s usually away from the home. But in many cases, rainwater will gravitate towards the walls of a basement.

I know what you’re thinking: Why does that matter if the basement is sealed? Well, water can still do damage to a tough material like concrete.

You see, water always finds the path of least resistance. No matter how well-built your basement is, there could be tiny cracks for water to get through. This could be a hairline crack caused by your foundation settling. Or, it could be weakened mortar joints.

Whatever the case may be, that point of entry will only get worse with time. Before you know it, you’ll have issues like mold to deal with. In the worst-case scenario, you might experience a flood after heavy rains or snowfall!

A sump pump works to eliminate those problems. It directs water away from your basement, ensuring that it can’t pool in your home and cause any major damage.

How Do Sump Pumps Work?

The concept behind a sump pump operation is pretty simple. These devices are installed about two feet below the lowest point in your basement. They are put inside a small hole called a sump pit.

Now, when rain falls outside, the water will seep into the soil around your home. It will continue to fall until it gets next to, or below, the walls of your basement foundation. The water then collects into the sump pit.

Once the sump pump detects the presence of water in the sump basin, which is the area where the pump itself is, it will turn on to push it through the discharge pipe. Sump pumps act very similar to a pool or pond pump. They utilize impellers to create suction force. However, many models create centrifugal force instead of standard upward force. That way, the water can continue to collect as it works.

Typically, discharge lines are 10 to 20 feet away from your home and on the ground level surface. The way the sump pump triggers can vary based on the unit’s design. More on that later!


Types of Sump Pumps Available

While all sump pumps are built to accomplish the same goals, there are a handful of different types of pumps to choose from. The right option for you will largely depend on the design of your basement and your needs.

Primary Pumps

A primary sump pump is your first line of defense. It’s the baseline that every home should have.

Within this type, there are two core designs: submersible and pedestal. A submersible sump pump is just what it sounds like. The unit sits inside the sump pit and becomes submerged in water whenever the basin fills up. Pedestal sump pumps, on the other hand, sit above the pit. Usually, it’s secured to a pedestal and features a separate inlet to suck water out of the pit.

Backup Sump Pump

Next up, there’s your backup system. While your primary pump is going to be doing all the heavy lifting, you can’t rely on it alone to keep your basement dry. What if the power goes out during a heavy storm? If you’re only using a single primary pump, you’re out of luck!

A battery backup pump kicks into gear when the primary one ceases to work. Generally, backup sump pumps will provide several hours of operation. They should buy you enough time to get power up and running again.

Combination Sump Pump

A combination pump is the best of both worlds! Essentially, they’re two-in-one systems that combine the primary pump with a battery backup system.

When your home is getting electricity from the grid, it runs on standard AC. But the moment you lose power, the battery system will take over.

Sewage Sump Pump

Finally, there’s the sewage sump pump. This is a good option if you experience clogs regularly. Clogging can result in an airlock, which creates backpressure and prevents water from flowing through the discharge line.

A sewage sump pump is able to handle large solids in addition to water. As the name would suggest, these pumps are usually part of sewage water systems. However, you can use them as a standard sump pump as well.


Key Considerations When Choosing The Best Quiet Sump Pumps

In addition to the type of machine you need, there are a lot of considerations to make when upgrading your sump pump. These aren’t like ordinary appliances. They’re much more important! So, you shouldn’t take this decision lightly. Here are some of the most crucial factors to consider as you shop for a quiet sump pump.

Noise Levels

If you don’t want to deal with a lot of noise while you’re trying to enjoy your basement, pay attention to estimated noise levels. Some manufacturers will provide decibel levels to give you a better idea of what to expect.

Always aim for a lower decibel rating. No sump pump is going to be completely silent or soundproof. You may still hear a subtle humming when it turns on.

That said, a well-designed motor can significantly reduce the noise you hear. Plus, it prevents grinding, clanging, gurgling noises, and other jarring sounds.

If you can’t find decibel ratings, take a look at the horsepower the pump provides. The more robust the motor is, the louder the unit will be as a whole.


While horsepower does impact noise, you should never sacrifice the performance of your sump pump to get a little bit of peace and quiet. There are many things that you can prioritize noise over efficiency, but your sump pump is not one of them!

You must choose a pump with enough horsepower to deliver gallons of water away from your house as quickly as possible. There’s no exact science to finding out the appropriate horsepower rating. It all depends on the depth of your basement, the drainage area, the distance to the discharge site, and more. Consider speaking with a plumber to get a professional opinion on how much power you need.

1/3 horsepower is usually efficient enough. But, you might have to upgrade to 1/2 horsepower or a full horsepower if you have a larger basement.

Switch Design

The best quiet sump pumps rely on switches to trigger operation. There are a few different kinds of switches available.

The most basic is the tethered switch. Tethered switches have a floating ball like the ballcock in your toilet. When the water level rises to a certain point, it triggers the pump. A tethered switch requires a larger pit, so keep that in mind.

Next, there’s the vertical switch. Also called a vertical float switch, these systems work similarly to tethered ones. The main difference, however, is the path of the switch is fixed. As a result, they don’t need a huge sump basin to operate. The one downside is that they tend to have a shorter lifespan than a tethered switch.

Finally, you can get an electric switch. These switches don’t have moving parts at all! Instead, they rely on an electrical signal to tell the pump when there’s water present in the basin.

Build Quality

The construction quality of your sump pump matters more than you think. These machines are exposed to water regularly. If you have a submersible model, the unit may sit in water for a long time before the basic accumulates enough to trigger the pump to operate.

A thermoplastic sump pump is good if you’re worried about issues like overheating. The material is lightweight and doesn’t have as much of a reaction to continued water exposure as some other materials.

Another option is stainless steel. Stainless steel is heavier and can last a bit longer than plastic units. However, despite the name, the impeller inside can succumb to corrosion if the unit sits in water for too long.

If you want the best in durability, go with cast iron. Cast iron sump pumps are heavy, stable, and long-lasting. Many manufacturers apply a layer of powder coating or epoxy to add even more protection to the system.



The most reliable and best quiet sump pumps can provide you with the peace of mind you’re after. These units will keep your downstairs domain free of moisture without the headache-inducing sump pump noise! Make sure you take the steps to maintain and test your sump pump regularly! Also, invest in some professional installation services if you’re not comfortable with your plumbing skills.

Once your sump pump is up and running, you can get back to enjoying your basement!
