Types of Sump Pumps

Whenever there is a flood or risk of flooding in your basement, the best defense you can put up is a sump pump which will help remove all the water from your basement. Depending on what you need, you can also find a sump pump for the pool or get an outdoor sump pump.

The good news is there are many different types of sump pumps, so you can find one that meets the requirements of your house.

Primary sump pumps:

All standard pumps typically found in most residential buildings are known as primary sump pumps. Usually, these primary sump pumps are powerful and can pump out at least a few thousand gallons of water every hour. 

Under this type, there are two different subtypes:

Submersible sump pumps:

As the same suggests, these pumps are fully submersible and can be placed at the bottom of the pit in your basement. This is one of the most sought-after types of primary pumps because you can submerge them underwater and work from the hole, which saves space, makes it more convenient, and also keeps the pump cool.

It’s also a quiet pump because it sits underwater; hence, the noise gets reduced when it reaches the surface level. It is pretty expensive compared to the pedestal ones but very high performance.

Pedestal sump pumps:

These pumps work the opposite of how a submersible pump works. They come with impellers that can be placed in the sump basin while the actual motor is placed outside the basin.

These motors are much cheaper than the submersible ones and can be easily accessed. You can also use them in smaller sump pumps because you don’t have to place the entire motor underground.

Backup sump pumps:

These are alternative pumps installed in homes and used in a power outage. Since most primary pumps run on electricity, you can have a backup pump that will do the work when the power is out. They typically run on hydropower or have battery backup.

These backup pumps are entirely optional and are available in two different subtypes:

Water Powered backup sump pump:

These backups use the city water to create a type of suction that increases pressure in the sump pit line. This suction power draws out the water and removes the unwanted water from your house.

The good thing is that you never have to worry about running out of power or battery since the city water supply is virtually endless.

Battery-powered backup sump pump:

These are much more expensive than the water-powered ones but are more popular because of their convenience. With a backup battery pump, you don’t have to worry about plugging in the pump to a power socket on the wall. 

Using a submersible pump, you can place the battery near the pump or outside the sump basin. You only need to consider that you may run out of battery power if you don’t keep it charged.

Multi-use submersible utility sump pumps:

These portable pumps can quickly move around from one place to another. They are also multi-functional and have many added features depending on your requirements.

The only drawback is that they are not automatically run, so you need to power these pumps manually.

Buying Guide

As discussed above, many kinds of sump pumps might make it hard for you to decide which one to buy. While the type of sump pump you buy entirely depends on your individual needs and preferences, you need to consider a few key factors. 

Let’s take a look at the primary things to consider before buying a sump pump:

Horsepower

The most crucial factor is the pump’s HP. The higher the HP, the more gallons of water per hour it can remove. Hence, this depends on the condition of water logging or water accumulation in your house and gets a pump that will do the job efficiently.

Core Material

Since power units like these pumps are a little investment and a primary need in many households, durability is a major buying factor. Most sump pumps are constructed with heavy-duty materials to ensure their longevity. 

Always look for pumps made of materials like long-lasting thermoplastic or industry-grade cast iron with some coating on top that prevents corrosion from the water.

Not just the outer body, but also consider what the insides of the motor are made of. Stainless steel is corrosion resistant, so it’s an excellent material to check for when it comes to the internal parts of the engine.

Basin Space

Most sump basins in residential buildings are about 30 inches deep and 18-14 inches in diameter. In most cases, these sump basins can fit pumps that allow for pumping between 26 to 30 gallons of water.

The smaller your basin, the more difficult it will be for your pump to work because the basin will fill up pretty quickly and need the pump to keep running. 

Also, if you are planning on getting a submersible pump, you will have to consider the side of the basin even more since the pump needs to be underground in the water.

Switch Type

You will find that sump pumps have digital and manual switches which you can flip to turn your pump on and off. Whichever one you go for depends on your preference. The main job of these switches is essentially the same- to run the pump on and off as needed according to the water levels.

However, digital switches seem to do a better job removing all the water from your sump, unlike manual switch pumps, which turn off after reaching a certain water level. This means that you might still experience a certain level of flooding.

Debris filter

You’re probably aware that in most cases, you will be faced with water accumulation filled with small or large chunks of debris. Some sump pumps come with an inbuilt debris filter which screens out the junk and sucks in only the water. 

The problem is that the suction holes can get clogged with prolonged use. Other pumps also feature a no-screen intake debris filter, which means that it can suck in the solids and eject them out with the water they are currently removing. Pumps with this feature are much more expensive but are more convenient in the long run.

Alerts

This additional feature warns you about the status of the pump and the process of removing water. More advanced pumps even have an alert system that alerts you when the water level rises.

Power Source

Another critical point to consider is the power that these motors consume. These days you will even find energy-efficient pumps that run on low amperage. This will save you a lot of money on your power bill.

You can also consider getting a backup battery to help power the pump when you need to or when there is no power.

What is the best sump pump to buy?

According to our research, the best pumps are submersible ones with high horsepower and a large capacity to pump out water. Also, consider if you can operate the pump via battery because you might also need to use the unit during power outages.

Submersible pumps are more convenient to use and operate, making them more user-friendly, although you will need to have a more extensive basin to submerge the pump underground.

How do I choose the right sump pump?

Before you buy a sump pump, make sure that you consider the size of the sump basin, how much water gets accumulated in the sump and how much you will need to pump out, and also the frequency at which you will need to use the pump.

Accordingly, you can decide if you want to get a pump you can submerge in the water or a pedestal if you have a smaller basin. The amount of water you expect to remove from your basement will also play a massive role in how much HP you want your pump to be.

Do sump pumps smell?

Yes. If you don’t use the sump pump for long durations, it can develop an unpleasant odor. If you don’t keep your sump pump running, bacteria and mold can start to grow, which produces this smell.

How often does a sump pump need to be cleaned?

It would be best to clean your sump pump at least once every year.
