Submersible and non-submersible are 2 different types of water pumps. Both are good enough for rainwater tanks that deliver enough pressure to send the rainwater where it needs to go.

Picking any of the pumps is critical because both are efficient in terms of performance. Buying both types is weird, and people get confused, thinking about which one to choose.

This submersible vs. non-submersible pump guide will help you to get rid of the confusion.

Let’s learn more.

Submersible vs. Non-Submersible Pump

What is a Submersible Pump?

This type of pump is completely submerged in a pond, tank, or other areas. A submersible pump can be used for many applications.

They are a good performer when pumping larger solids or crushing larger solids into smaller ones. Similarly, these pumps are efficient in removing wastewater at high pressure and flow rate.

Submersible pumps come in 4 different types: solar, submersible, sand, and irrigation.

Key Features:

  • Self-primed
  • High efficiency
  • Corrosion-resistant
  • Lightweight
  • Easy to use

What is a Non-Submersible Pump?

From the name itself, you can get an idea of this pump type. They are not submerged into an area to remove water and installed beside a tank or somewhere close. Most homeowners use the non-submersible pump in their home.

Many people think that non-submersible water pumps are water-proof, but it is not the fact. However, many models are available with the water-proof feature. It is also used for removing water from different areas like ponds, crawl spaces, or tanks.

Also, special care is necessary if the pump is exposed to direct weather.

Key Features:

  • Versatile
  • Budget-friendly
  • Explosion-proof
  • Flooding prevention
  • Dry application design

Differences between Submersible Vs Non-Submersible Pump?

Since both water pump type is quite similar in functionality, but they have dissimilarities too. Let’s look below in a broad sense.


In terms of noise, submersible pumps are the clear winner. The non-submersible pump creates much noise when working.

The interesting thing is, different models of non-submersible pumps create different noise levels. They come with a cover, and the cover absorbs noise. But this option is not enough to bring down the noise to a comfortable level.


Non-submersible pumps are easy to repair and service compared to submersible pumps.

Repairing a submersible pump is difficult since they are installed inside the water tank, and you may require a ladder to reach the pump area. Removing a submersible pump from its position is laborious. Even after uninstalling, there is no surety that it can be repaired.

On the other hand, when a non-submersible pump starts malfunctioning, locating the issue is much easier and replacing the parts is so simple. Also, replaceable parts are inexpensive and readily available. And replaceable parts of submersible pumps are expensive.


Submersible pumps are more expensive than non-submersible pumps. It is because submersible pumps are constructed with water-proof and sealed-resistant materials.

Servicing of submersible pumps is costly too. In contrast, a non-submersible pump will not cost you more.


Do you have available space near your water tank? If the answer is yes, choose a submersible pump. However, you will need to keep in mind that enough room is necessary to let the pump in and out of the tank. It is essential when the submersible pump is installed under a deck.

Which Pump to Choose?

So, time to decide which pump to choose. As stated earlier, both pumps are efficient in delivering the best outcome. All you need to do is, know your preference, and keep the below point in mind.

A submersible pump is suitable if you have enough space to install a pump and don’t have any issue costing money.

If you are looking for an affordably priced efficient pump, buy a non-submersible pump. It performs quietly, which means when operating, it will not hamper your sound sleep.

Final Words

Before buying a water pump, the general thumb rule is learning your requirement and then deciding to go for the ideal pump. I believe this submersible vs. non-submersible pump write-up will guide you on the right path.

Besides, it would be best if you buy a water pump from a top-rated brand. It is because top manufacturers use all premium quality material so that a user can get long term service. Don’t invest your money by buying a water pump from cheap manufacturers.

  1. thank you for such a valuable knowledge about submersible pumps.

  2. I bought a non-submersible pump online but it does not really pump water. Seller said it is self-priming but it does not pump water…there is no suction at the inlet. I don’t know what else that I don’t know why it does not work

    • If your water pump is not producing the desired pressure, it might be because you lost its prime. The fix is simple! Turn off power to the pump and remove the gauge with bushing or bladder tank from the top of the pump. Pour some water into a pot deep enough for all but one inch of the bottom part of your pipe (gently) to submerge in order to let gravity push any air out as well as filling up to create more suction on the remaining gas inside tube walls before turning back on again after ten minutes when full force should have been regained by now – just make sure this type doesn’t clog too easily first!
