To build your own pressure washer system at home is not as difficult as it seems to be if you have sufficient components and instruments for setup.

In your machine, you can use a motor that can be run by either electricity or gasoline, a pump to pressurize the water, and some hoses for the entire setup.

Being an ordinary person, can I set up my own pressure washer system?

The answer is yes, provided you have all the necessary components to make it up. If we see the price of a pressure washer in many cases, we don’t have enough budgets to afford it. This is when you should think about making your own pressure washer with spending a tiny amount in buying the required parts.

Cleaning with a pressure washer is much effective than general cleaning, and for this reason, we desire to have a machine like that. This machine can be used to clean your various stuff such as garage, car, fence, floor, patio, etc. In this article, we’ll focus on how to build a pressure washer system with a minimum budget.

Pressure Washer System Parts

To make your own pressure washer at home, you will need quite of few important parts, and for that, you have to understand how a pressure washer works. This kind of machine takes water from a source into the pump where pressure is created on the water and sends it out through the outlet hose.

The pump is propelled by an engine which can run either by electricity or by gasoline. Gasoline engines are comparatively more powerful than electric ones.

Firstly you will need a metal frame to hold the engine and pump on top of it. To make it flexible to move around, it’s better to choose a frame with wheels. A pump and an engine are needed; you can take the engine of a lawnmower which comes at a low price, and it’ll be enough for you. You have to buy two types of hoses, a hose that can tolerate the high pressure of water and a regular garden hose. You also have to buy a spray gun with some nozzles that are important for your different cleaning types. Finally, you will need a toolbox to attach them together.

How to Build a Pressure Washer – 7 Easy Steps

When you are done with your shopping of all the required components, you have to sit in a place start following the below steps:

Step 1

Place the frame in flat space and put the engine and pump on top of it. Make sure you have placed the engine at the center of your frame for a proper balance. This is important because the engine will vibrate while running, and there is a chance of falling down if not placed at the center. Attach it with some screw with the frame so that it doesn’t move.

Step 2

In this step, you have to connect the power supply to the engine and check if it’s propelling the pump properly or not. Connect the power cord to the electric supply in case your engine is an electric one.

If you have a gas engine, fill it up with sufficient fuel. Start the engine, check if it’s working fine, and don’t let it run for a long time.

Step 3

Now it’s time to connect all the hoses to your machine. One end of the garden hose you have to attach to your pump’s inlet and the other end to the water tank or water supply.

In the same way, one end of the high-pressure hose you have to connect to the pump’s outlet, and the other end needs to be connected to the spray gun. Make sure that all the connections are firmly attached, specially the HP hose connections.

Step 4

Next, you have to connect the spray nozzles to your spray gun. You will find different types of nozzle tips such as 0-degree, 15-degree, 25-degree, 40 degrees, etc.

You will get the most power when you use a 0-degree nozzle, and the water flow will be concentrated at one point like a pencil. If you need to cover a wide area where water force is not important, you can use the 40-degree nozzle.

Step 5

If you want to apply detergent with your machine, you have to install a detergent connector at your pump’s outlet before the HP hose. This connector allows the cleaning detergent solution to get into the hose and be mixed with the pressurized water. If you don’t intend to apply soap with your machine, you can skip this step. In case of using soap or detergent, you should use a soap applicator nozzle with your spray gun.

Step 6

In this step, you have to check all the connections and parts are appropriately attached to their respective places. Fill the water tank or turn on the water faucet if your garden hose is connected to the faucet.

Step 7

Now it’s time to give it a trial. Switch on the power connection and start the engine. The engine should propel the pump, which should intake water from the tank and let the water out through the outlet hose and through the spray gun. In the beginning, it might take a few seconds for the entire process to complete. If the entire process is working fine, your machine is ready to do your cleaning job.

Conclusion

Once you closely follow all the above steps, you will get your desired pressure washer. If you have some mechanical knowledge, it’ll even be easier for you to build the machine. Building a pressure washer, on the one hand, will give you a proper cleaning solution, and on the other hand, you can make it a low-budget machine. You just have to give your time and make a little effort to take the hassle. You will get few extra facilities if you buy a pressure washing machine but, if you don’t need them, why wasting money on them.
