How To Select The Best Sump Pump

What is the best submersible sump pump to buy? It is a question that bothers most home and landowners. Purchasing the right product for your lawn or basement is not an easy task. There are criteria that need fulfilling, things that need to be considered, and much more.

Thus, let us look at the things that need your attention the most before buying a sump pump.


Submersible pumps that actually last for a long time cost a little more than the cheaper ones. On the other hand, you can easily replace a cheap product because it won’t hurt the budget.

Now, what if your pump stops working when you need it the most? A failed pump can lead to high property damage, especially if flooding occurs in your basement or storage area.

Therefore, your best option is to purchase a pump that comes with a sturdy build and also a few years of warranty even if it is costly. However, if you don’t want to put all your eggs in one basket, then you can always buy a cheaper yet efficient pump and keep a backup if it ever fails.


Now durability is also as important as longevity. If you have a general idea about pumps and how they work, you should know that they have to work in the harshest conditions.

Most of the time, pumps are highly susceptible to corrosion, impacts, and much more due to the environment they are kept in. So, make sure your pump comes with solid materials such as cast iron, stainless steel, thermoplastic, or special features that can protect them from the harsh conditions of the environment.

Power Source

Usually, sump pumps run on electricity, which is amazing because it is much cheaper than fuel. However, it has a crucial flaw too. If you ever face a power cut during a heavy storm, you will end up with a flooded basement, and trust us; it is not a pleasant scenario.

Therefore, it is a wise move to keep a sort of backup. To prevent disastrous situations, you can either keep a backup pump that runs on a battery or something that features both types of power sources (battery and direct electricity).

However, submersible pumps that run on both electricity and battery may cost a little extra. So, we suggest you look at our sump pump reviews to know which one meets your requirements.

Switching System

Submersible pumps come with different types of switching systems; among them, three are most common and can often be seen in a product. The diaphragm is not conventional among the different switching systems. It detects the pressure of water and starts pumping in regards to it.

Capacitive and vertical switching systems are quite the same. A capacitive switch uses integrated microprocessors, which measure the level of water and start to work. When the water level reaches a certain level, it turns on the pump automatically.

The vertical switching system also works in a similar way. It also turns on automatically when the water reaches a specific height. However, unlike capacitive switches, it travels vertically in the sump pit. It is usually installed at an angle of 90-degree, and you can use it with basins that have a 10-inch diameter.

Strength (Horsepower)

HP refers to the pump’s ability to push or pull out water. Thus, the required strength depends on how high and far your sump pump needs to push out the water.

If the distance from your sump pit to the drainpipe is less than 6-8 feet, then a 1/3 HP motor can easily complete the task. However, if the distance is higher, then you will need something with more horsepower.

Water Flow (GPH)

The amount of water your pump can deliver depends on the power of the motor. The flow rate of a product is determined in gallons per hour or GPH. Usually, a heavy-duty pump with high horsepower has a water flow rate of more than 3000 Gph.

Nevertheless, the amount of water flow you need depends on the environment of your area. If you face frequent storms or heavy snowfall, you will need something with high Gph to keep your basement dry.

However, if you do not require such pumping power, then you can always save some cash by going for a pump featuring less water flow rate.


Having good or the right materials will ensure the durability and longevity of the pump. Thus, it is a crucial consideration before purchasing a product.

Usually, pumps that feature stainless steel, cast iron, or thermoplastic construction are better than others. Stay away from cheap or plastic materials as it will lead to different issues and won’t last for a long time as well.


Now, most of you may think, why do you need to worry about safety while purchasing a pump. In case you didn’t know, sump pumps are set in a pit, which is often wet due to frequent flooding.

This may lead to faulty wires, which can lead to shocks. Therefore, to keep yourself and your pump from harm’s way, buy a pump that assures safety from electrical shocks. You can also get something that features an automatic float switch if you want to keep yourself away from the pump when the basement floods.
