The Difference between Submersible Water Pumps and External Surface Mount Water Pumps for Rainwater Tanks

January 26, 2020

When purchasing a water pump, there are different types that you can install, and connect to your rainwater tank. 

You can choose from a submersible water pump or an external water pump. The question is, which one should you choose? We hope this article will make the process of choosing your rainwater tank pump a little easier.

A submersible water pump is placed inside the rainwater tank and is designed to pump water vertically through the roof of the tank.

External Water Pump for a Rainwater Tank explained.

An external pump is the most popular pump for rainwater tanks. The external water pump is usually positioned next to the rainwater tank. It is highly recommended to protect the pump from the weather with a pump cover.

External pumps are also known as above-ground pumps or surface mount pumps.

So which pump should I choose? What are the Pros and Cons?

There are advantages and disadvantages to both pump types. Here are a few things to consider when making your purchase decision:

  • Price – In most cases, a submersible pump will be more expensive, as it has been made with waterproof internals, so it can be submerged into water, inside the rainwater tank.
  • Noise - Being submerged and surrounded by water, a submersible pump is normally quieter than an external water pump. 
  • Energy Efficiency – An external or surface mount pump uses more power as it is required to pump and suck, where a submersible pump only needs to pump water. 
  • Maintenance and Accessibility – An external water pump will be easier to maintain and service as it is much easier access, where a submersible being inside the tank, it will require some dismantling to access and maintain the pump.
