  • Secure the Materials

The first thing you should do is get the materials. The basic things that you’ll need is a base, a frame, a motor, a pump, a tank, and a hose. 

  • Position the Base

Next, put all the materials into position. First, you’ll need to put the base on the floor and place the motor in the center of the base. After that, put the frame on top. To keep the motor in place, you can lock it on the base with some utility bolts and fasteners. 

  • Place the Tanks

For pressure washers, you’ll need two kinds of tanks– water and air tanks. You just have to secure them at the rear area of the frame. Fasten them carefully so that they won’t fall off. Take note that you don’t really need to learn how to build a pressure washer tank. You can buy those at the store. 

Place air and water tanks along the back of the frame area and make sure to secure these tanks to the frame. Connect the hose to the faucet. After which, you can now connect the hose to the water tank.

  • Connect the Hose to the Water Source

For the hose, you can use a simple garden hose. Simply connect the garden hose to your faucet for the water source then connect the other end to the water tank.

  • Attach the Water Pump

Next, take the water pump and attach it to the air and water tanks. You can attach them using a pressure hose.

  • Install Electric or Gas Components

In this stage, you’ll now decide whether you’ll want a gas-powered pressure washer or an electric pressure washer. Attach the necessary components to the motor area and fill in the necessary fuel. Gas will be needed for the gas-powered types and an electrical connection for the electric power washers.

  • Attach the Nozzles

Do you have to learn how to build a pressure washer nozzle? No, because you can buy any nozzle from the store. Just make sure you get the nozzle that’s appropriate for your washer and you’re good to go.

  • Test the Pressure Washer

The last step is to simply test the pressure washer. If everything works well for around 2 minutes of continuous use, then your pressure washer is good. If not, then there are probably some parts that you’ll need to double check again.

  • Start Cleaning Your House

Now that everything is good, you can start cleaning your house and your patio!


As you can see from our guide above, it’s actually not that hard to make a pressure washer. So long as you buy all the necessary things needed to build your machine and follow the steps on how to build a pressure washer.
