How to Fix Pressure Washer Soap Injector (Easy Guide)
Learn how to fix pressure washer soap injector with our simple and easy to follow guide. This can help you troubleshoot and address issues with your appliance.
While pressure washing with water can help rinse away the light dirt on the surface, you’ll need chemicals or detergent to help you take out all of the stubborn dirt that sticks. While most people just apply the chemicals directly with the spraying system, using a chemical injector is the most recommended method of using chemicals since it would concentrate the chemicals in the stream.
However, these pressure washer parts can be a bit delicate to handle, which is why they may not work the way you want them to work at times. So, if you happen to have a problem with your soap dispensing, you’ll need to learn how to fix pressure washer soap injector.
What Is Pressure Washer Soap Injector?
Now before anything else, it’s pretty important to know what exactly is a pressure washer soap injector and how it works. As already mentioned above, it is a device that limits the stream of water via a small hole to make the stream more concentrated.
Another interesting feature about this little device is that it has a port wherein the chemical soap is brought into the stream through vacuum suction.
The trick here is to make sure that the pressure isn’t too high when using this appliance because the high pressure will block off the vacuum. You’ll need low pressure in order to draw out the chemicals and concentrate them into the water stream.
At the same time, there is a valve that helps regulate the drawing of chemicals so that the water doesn’t enter the port where the chemicals are drawn as this may drown out the chemicals.
Easy Steps on How to Fix Pressure Washer Soap Injector
Now that you know how the pressure washer soap injector works, it’s easier to learn how to fix pressure washer soap injector problems. The first step in fixing issues like these is to first start troubleshooting pressure washer soap injector. Once you identify possible problems, you’ll immediately know how to fix pressure washer chemical injector.
Here are some tips on how to do just that:
Check the Pressure Nozzle
If you notice that the chemical soap cannot seem to be drawn out from the port, then there is a possibility that the backpressure from the water is a little bit too high. In this case, the first thing that you have to do is to check the nozzle.
If ever your pressure washer is sporting a high-pressure nozzle, then you’ve already found the cause of your problem. High-pressure nozzles are known to block off the soap injectors’ chemical port. That said, you should just switch to a low-pressure nozzle and check if that works. To be specific, recommended nozzle sizes range from 30 to 50 when dealing with low pressure.
Check for Blockages
Another common problem that you may experience with regard to the chemical injector would be clogging at the nozzle or valve area. This is usually caused by dirt entering the chemical tube. This can be easily fixed by cleaning out the dirt from the affected area by checking the tube, nozzle, and valve to see which area is affected. Thus, clogging can then be prevented if you use a chemical filter on the tube. This filter will help prevent dirt or debris from sticking on or going through the chemical tube.
Check for Clogging
Clogging or blockages are not only caused by dirt or debris but also by components that need to be replaced already. That said, you may think right away that the chemical injector needs to change. However, it may be other parts that could have a problem. That’s why you need to troubleshoot for the problematic part.
The best way to do this is to remove the hose and other accessories from the pump and see if the unit is working properly. If it siphons detergent, then the problem lies within one of the parts of the hose. From there slowly add back all the parts one by one like the soap injector, the valve, the nozzle, etc. If at any point the soap is not siphoned, then you’ll be able to tell which part is the problem.

From there, you’ll be able to fully troubleshoot not only the soap injector but your machine itself.
With that, it’ll be easy to know whether or not your soap injector is damaged, clogged, or simply just used wrongly. In any case, our guide will be your guide.
