Detergent Injection Kit

The detergent injection kit siphons detergent from a container, allowing you to spray detergent with your pressure washer.

Before replacing your detergent injection kit, make sure that you are using a low-pressure nozzle or gun (depending on your model) and the detergent injection’s siphon hose isn’t clogged. If the detergent injection valve still can’t draw detergent from a pressure washer detergent container, then your detergent injection kit may need to be replaced.

Don’t forget to switch to the detergent (black) nozzle tip when you are applying detergents.

Follow this easy-to-follow instruction guide to learn how to replace the detergent injection kit on your Simoniz gas-engine pressure washer.
