Building a M-5 type X-jetting gun the Cleaned by Pete way
Using a safe low-pressure to wash homes or businesses is a must while washing. Pressure is good, but to much pressure can harm softer surfaces. Needing the right equipment for the job is a must. This is one of those must builds. It fits a nitch in our tool and equipment. I have written about some of the nozzles I use in previous blogs.
This build is a variation on a X-jetting system and a M-5 style nozzle. To start the build these items will be needed. You can adjust your list to fit your needs.
 |
| 3/8" to 1/4" brass reducers |
 |
| a pressure washing gun with the approbate psi rating for your washer |
 |
| One "down-stream" injector using an adjustable one is worth the money |
 |
| one 12" lance or one to your liking, I used a 16" lance on mine |
 |
| and one push-pull adjustable nozzle again matched to your psi machine output. |
Using Teflon tape on all connections to reduce any chance of leakage is recommended. The process is quite simple from here. I used a 3/8" injector because they are much easier to source and at a bit lower cost. Using a fixed injector is fine but I like the ability to adjust the flow of the solution entering the system. When finished you should have something to look like this.

| First off the gun is a 1/4" to 3/8" brass fitting, followed by another fitting and then the lance. You may want to place the injector on the end of the lance next to the nozzle if you wish. |

| The adjustable fan to stream / soap to rinse nozzle place on the end. |
 |
| You should have something like this when finished with your work. |
With all parts assembled you are read for use. Most of us are familiar with the the down-stream injector. When the back-pressure is reduced by using a larger, free flowing nozzle, it will start do draw soap do to a low pressure zone created in the injector do to a venturi. By opening the valve more or less soap can be drawn in. The adjustable nozzle is the next item moving it in and out "push-pull" you create pressure or a freer flow. By twisting you create a stream or a fan pattern.

| Twist and push pull to adjust |
This has been a very useful and a must need in the equipment I use. Using it while battling mold, algae and mildew, to clean and wash homes and businesses. Is it right for you? build one and find out.
