how to make a water pump at home?


A water pump is an essential tool for anyone who needs to move water from one location to another. Whether you need to transfer water from a well to a storage tank or pump water out of a flooded area, having a water pump on hand can make the job much easier. While there are many different types of water pumps available on the market, making a water pump at home is not as difficult as you may think. In this guide, we will provide you with step-by-step instructions on how to make a simple water pump using basic materials that you may already have lying around.

Materials Required:

To make a simple water pump at home, you will need the following materials:

  • PVC pipes (1 inch diameter)
  • PVC elbows (1 inch diameter)
  • PVC Tee (1 inch diameter)
  • PVC end cap (1 inch diameter)
  • Electric motor (12V)
  • Impeller
  • Rubber gasket
  • Screws
  • Drill
  • Sandpaper
  • Electric wires
  • Battery (12V)
  • Hose (1 inch diameter)

Step 1:

Build the Pump Body The first step in building a water pump is to create the pump body. To do this, you will need to cut the PVC pipes into the following lengths:

  • Two pieces of PVC pipe (6 inches each)
  • Two pieces of PVC pipe (4 inches each)
  • One piece of PVC pipe (3 inches)

Next, connect the pieces of PVC pipe together using PVC elbows and tee. The 6-inch PVC pipes should be attached to opposite ends of the tee, and the 4-inch PVC pipes should be attached to the remaining openings of the tee. The 3-inch PVC pipe should be attached to the top of the tee using another PVC elbow. Finally, cap the 3-inch PVC pipe with the end cap.

Step 2:

Build the Impeller The impeller is the component that will move the water through the pump. To make the impeller, you will need to take a small piece of PVC pipe (approximately 1 inch in length) and drill a hole in the center. Next, take a small piece of rubber gasket and cut it into a circular shape that will fit snugly inside the PVC pipe. Finally, attach the impeller to the electric motor using screws.

Step 3:

Attach the Impeller to the Pump Body Take the impeller and attach it to the top of the 3-inch PVC pipe using a PVC elbow. The impeller should be positioned so that it is directly above the tee.

Step 4:

Connect the Electric Motor Attach the electric motor to the side of the pump body using screws. Connect the motor to the impeller using a piece of wire. Finally, attach the battery to the motor using another piece of wire.

Step 5:

Test the Pump To test the pump, fill a bucket with water and place one end of the hose in the bucket. Place the other end of the hose in a different location where you want the water to be pumped to. Turn on the pump by connecting the battery to the motor. The water should begin to flow through the hose and out of the other end.


While this is a basic design for a water pump, it can be modified to suit your specific needs. For example, if you need to pump water from a well, you may need to add a foot valve to the bottom of the pump to prevent the water from flowing back into the well. Additionally, you may want to add a pressure gauge to the pump so that you can monitor the pressure of the water as it is being pumped. With a little bit of creativity and experimentation, you can create a water pump that is customized to meet your specific needs.
