The inlet adaptor on my Pressure Washer is broken

Quick Answer

If the inlet adaptor on your pressure washer is cracked or broken, this is often caused by overtightening it when connecting to the machine. Excess force can stress the plastic threads and lead to splitting.

If the inlet adaptor was missing or damaged when your product arrived, a replacement can be supplied under warranty.

Before You Start

Before inspecting or replacing the inlet adaptor, make sure:

• The pressure washer is switched off
• The water supply is disconnected
• There is no pressure remaining in the system

Always:

• Handle plastic fittings carefully to avoid cross-threading
• Check threads for damage before reassembly
• Ensure the adaptor is aligned correctly before tightening

Important: Never force the inlet adaptor into the machine, as this can permanently damage the housing.

Common Causes of Inlet Adaptor Damage

The inlet adaptor can become damaged due to:

• Overtightening during installation
• Cross-threading when connecting the water hose
• Using incorrect fittings or incompatible connectors
• Repeated removal and refitting over time
• Impact damage if the machine is dropped or knocked

How to Check the Damage

Follow these steps:

1. Inspect the adaptor threads

Look for:

• Cracks in the plastic
• Stripped or flattened threads
• Signs of stress or splitting

2. Check the machine inlet port

Ensure:

• Threads inside the machine are not damaged
• No debris is blocking the connection point

3. Compare with a replacement (if available)

If you have another adaptor, compare the fit and thread condition.
