What causes 'Pump Cavitation' in pressure washers, and how do you prevent it?

• Using dirty motor oil in the engine
• Using too long of a high-pressure hose
• Inlet water starvation creating vapor vacuum voids that collapse and pit pump pistons; ensure adequate GPM water supply
• Running the engine with no spark plug
