​Can You Convert Air Compressor To Pressure Washer?

​Let’s say you don’t have a pressure washer, but you have an air compressor at home.

​Is it possible to just convert that air compressor into a pressure washer instead?

​The thing about an air compressor is that while it may have the same or higher pressure than that of a pressure washer, it may not have the necessary speed needed for pressure washing jobs. That said, it is not possible to convert an air compressor to a pressure washer.

How To Use Air Compressor Pressure Washer Attachment (Step By Step)

​1.​ Get The Air Compressor Moving

​The first thing you must do is turn the air compressor on and let the pressure inside build. In order to monitor the pressure, you just need to take a look at the gauge. The gauge will tell you the PSI level. The goal is to reach a PSI level of 30, at the very least.

​2. Connect The Garden Hose

​The next step is to simply connect one end of the garden house to the water source. This could be your garage or lawn faucet. Just make sure the end of the garden hose is tightly attached to the water source.

​3.​ Connect The Pressure Washer Attachment

​Take the other end of the garden hose and attach it to the pressure washer attachment, which is your air pressure. The water line is now connected to your pressure washer hose gun.

​4. Attach It Tightly

​Take the air hose from the air compressor attachment and attach it to the air line connector. Make sure it collects all the way until the end of the air hose. You should hear a sound when it goes all the way in.

​5.​ Test It Out By Turning On The Faucet

​After that, turn on the faucet and test its strength. If it’s stronger than usual, then it means it has worked. If not, then check all the attachments one by one and make sure all parts are tightly connected.

​6.​ Clean Your House

​The last thing that you should do is simply point the gun at where you want to clean and clean away!
