Ways to Connect a Chemical Injection Kit to Pressure Washer
There are usually two main ways to hook up a chemical injection system to a pressure washer.
The first is to use a built-in chemical injection port on the pressure washer pump itself. This is typically a small threaded valve or fitting designed to connect to the injection kit. You just screw the kit into the port and attach the chemical hose.
The second way is to use a downstream injector that gets installed after the pump. This type connects to the pressure washer wand or gun and uses high-pressure water to suck in and blend the cleaning solution. Downstream injectors are good if you're using really caustic chemicals that might damage the pump.
Both methods have their pros and cons, so you have to think about the kind of washer you have, the cleaning solution, and what you're trying to clean. The most important thing is to always follow the manufacturer's instructions to get it hooked up and working right.
How to Install a Pressure Washer Chemical Injection Kit
As above, we know that have two main ways to connect the injection to your pressure washer. Below, we will show you how to do detailed that.
Built-in Chemical Injection Port
Locate the chemical injection port on your pressure washer pump, typically a threaded hole.
Screw the fitting from the chemical kit into the port and hand tighten.
Connect the hose from the kit to your soap bottle.
Fill the bottle with soap solution.
Adjust the ratio knob if available.
Attach the wand and nozzle, then turn the pressure washer on to purge the air.
Trigger the wand and test the soap mixture. Adjust the ratio as needed.
Downstream Chemical Injector
Locate where you want to install the injector, typically on the pressure washer wand.
Attach the injector fitting, securing it tightly.
Connect the hose from the injector to the soap bottle.
Fill the bottle with soap solution.
Turn the pressure washer on and check for leaks at the injector fitting.
Trigger the wand and see how the injector draws in the soap. You may need to adjust the ratio dial or knob.
Test spray the mixture and adjust the injector ratio as needed to achieve the proper soap concentration.
