Q: How do I lower the pressure or is it not adjustable.
5 months ago- A: Hello, thank you for your question. This pressure washer’s output is not directly adjustable like a dial. Pressure is controlled by selecting the correct spray nozzle. Using wider-angle nozzles (for example, 25° or 40°) gives a gentler, lower-impact stream, while narrower tips increase surface pressure. There isn’t a built-in user control to set PSI to an exact lower value.5 months agoHelpful?
Q: What Size hose & quick connection 3/8 or 1/4 ?
2 years ago- A: The WPX3800 uses a 3/8 quick-connection.2 years agoHelpful?
