Saving water & reducing reliance on the municipal water supply is an important aspect of being 1 step closer to nature. If you even have a soft corner for nature, you should go with Rainwater harvesting. You can do this using a high-quality Rain tank pump by collecting the rainwater from your roof. 

Types Of Rainwater Pumps & Their Workings

The main component which is necessary for rainwater harvesting is the pump. The pump works as an agent for moving the water from the tank to wherever you need it. Several pumps can be used for rainwater harvesting, each having its pros & cons. Some of the pumps are listed below. 

Submersible pumps

These are the common type of pumps for rainwater harvesting. They are submerged in the water and are installed at the bottom of the tank, being submerged they are also very quiet & efficient. Though the price of this pump can be a little expensive as compared to other pumps.


This pump works on the principle of a submersible pump based on the centrifugal force. It has a rotating impeller covered by a cylindrical casing, and the impeller creates a vortex that takes the water into the pump. After all the working steps, the water is forced through the impeller and out the discharge port.

Diaphragm pumps

These are other types of pumps that can use for rainwater harvesting. They are not submerged, unlike the submersible pumps; instead, they sit on the top of the tank. Diaphragm pumps are less expensive than regular submersible pumps. Besides, they still can be louder and less efficient than them. 


Water pumps are positive displacement pumps that use a flexible diaphragm to move water. This pump is thin & has a flexible membrane attached to a piston or plunger. When the piston or the plunger is moved, the diaphragm is flexed & so it creates a pressure difference that moves the water. These pumps are used to pump up liquids that are corrosive, abrasive, or contain solids.

Solar-powered pumps

These pumps are a good option for people wanting a sustainable and environmentally friendly way to pump up the water. These pumps work on the sun’s energy, so they do not require electricity. However, they can be more expensive than the other types of pumps.


Solar-powered pumps use solar energy to power the pump motor, so their panels first collect the sunlight and convert it into electricity; the electricity is stored in a battery. The battery powers the pump motor & then the pump motor pumps water from a source to the destination.

Choosing The Right Type Of Pump

It would help if you went through with a few factors to make a useful buy.

Some of them are :

  • Size of your tank. 
  • Height of your tank. 
  • Type of water you will be pumping. 
  • Your budget. 

Once you have gone through everything, you can start shopping to buy the best rain tank pump.

Installation Of Rain Tank Pumps

The installation process is relatively simple, so it would not be hard for you. The basic steps are :

  • Connect the pump to the water supply.
  • Connect the pump to the power source.
  • Set the pump to the desired pressure.
  • Test whether it’s okay or not. 


Rainwater pumps are an essential part of the rainwater harvesting system. If you choose the right pump and install it properly, you can be sure about a reliable water source for your home or garden. You can review the necessary factors and buy the best pump accordingly so that you will be satisfied with your purchase.
