When I first decided to invest in a pressure washer, the Honda GX390 Pressure Washer Pump caught my attention. After extensive research and personal experience, I compiled this guide to help you navigate your purchase. Here’s what I’ve learned along the way.
Understanding the Honda GX390 Engine
The Honda GX390 engine is renowned for its reliability and performance. I appreciate how it provides a powerful output of 13 horsepower, making it suitable for both residential and commercial cleaning tasks. The engine’s overhead valve design ensures efficient fuel consumption and a longer lifespan, which is a significant factor for me when choosing equipment.

Taking care of my pressure washer pump has been essential for extending its life. Here are a few maintenance tips I found useful:

- Clean the Air Filter: A clean air filter helps improve performance, so I check and clean it regularly.
- Winterization: If you live in a colder climate, winterizing your pump is crucial to prevent damage from freezing temperatures.
Where to Buy
I’ve discovered that purchasing from authorized dealers or reputable online retailers ensures that I get a genuine Honda product. Websites like Amazon, Home Depot, and Honda’s official site often have competitive prices and reliable customer service.
