This design feature makes it easy to switch hoses or accessories without the need for additional tools. Ensure that the connection is clean and free of debris to prevent leaks or damage.
Types of Connections
There are commonly two types of connections: the standard bayonet and the screw-type. The bayonet connection is prevalent for its ease of use, while the screw-type offers a more robust and secure fit, often favoured in professional settings. Always check your model’s specifications to confirm which type is compatible.
Adapters and Compatibility
In some cases, you may require an adapter to connect different components. These adapters are fairly easy to find online or at local hardware stores. Always verify that the adapter matches the size and type of your existing connections to avoid frustration during setup. My experience has shown that mismatched connections can lead to unnecessary complications, so take a moment to ensure compatibility before making any purchases.
Step-by-step guide to attaching the pressure washer pipe
To begin, ensure your equipment is turned off and disconnected from the power source. This guarantees safety while you work on the connections.

1. Gather your tools
You’ll need the following items:
