What is a Soap Injector for a Pressure Washer?
IN THIS ARTICLE:
A soap injector is a component of a pressure washer that permits soap or detergent solution to flow from a bucket or tank to the pressure washer’s high-pressure hose through a pipe. The soap dissolves in the water and eventually runs out via the spray cannon onto the area to be cleaned. Generally, a soap injector is installed at the pump’s water output connection, where the water is discharged with tremendous force.
Why Is My Pressure Washer Not Pulling Soap
- It is critical to understand how a soap/chemical injector works before troubleshooting a pressure washer soap injector. It is a device that constricts or narrows a stream of water running through the nozzle in order to remove soap water from its container by suction.
- The narrow stream increases the water’s velocity, lowering its pressure and thereby drawing the soap toward the vacuum suction. It should be noted that the pressure inside the injector should not be excessive, since this would prevent the chemical from being suctioned. Rather than that, the water will flow directly into the detergent container from the stream.
- Additionally, a valve regulates the flow of chemicals from the injector. If the pressure of the flowing water stream is too strong, the valve restricts fluid flow back toward the soap container.
How to Repair a Soap Injector on a Pressure Washer
Once you understand how a soap injector works, it will be easy to understand why it is not operating properly. We will outline many troubleshooting procedures that you should attempt, as they will assist you in determining the reason and applying the remedy to resolve the issue.
1. Inspect the kind of nozzle:
If your soap injector does not seem to operate, it is most probable that the backpressure created by the moving stream of water is too great, preventing the chemical from sucking. To determine this, examine your nozzle and determine if it is a high-pressure or a low-pressure nozzle.
– The solution is to use a low-pressure nozzle:
If your pressure washer is equipped with a high-pressure nozzle, this is most likely the source of your injector issues. You should consult your user’s handbook to discover the nozzles that are recommended for the various pressure kinds. Generally, high-pressure nozzles are incompatible with chemical siphon/injector operation. Therefore, you should experiment with a low-pressure nozzle for your device to see whether it works.
2. Inspect for obstructions:
Another typical issue with chemical injectors is obstructions at the nozzle or valve region. This is often the result of material accumulating in the chemical injector tube. This stops the chemicals from being siphoned.
— Cleansing the dirt:
This issue may be rectified by filling the problematic region with debris and inspecting the tube, nozzle, and valve to determine which area is impacted. To avoid clogging, you may place a chemical filter on the tube. This filter prevents foreign dirt particles from entering the tube, ensuring that blockage does not occur.
