## Customer Reviews

### ⭐⭐⭐⭐⭐ Working well in second season of use
*by L***. on July 31, 2025*

Easy install.My OEM pump stopped working and needed to be replaced. This pump was far more affordable than the one offered by the manufacturer and has worked well for two seasons of moderate use.

### ⭐⭐⭐⭐⭐ Product was package will, and arrived on time
*by B***N on April 18, 2020*

I had some problems sliding the pump onto the shaft. The slot key kept sliding down preventing the pump from going all the way down. I used a screwdriver, preventing the slot key for sliding down to far. Then input my bolts on and tighten the pump down onto pressure washer.After making some minor adjustment, new plug, and air filter, it runs outstanding. My Karcher CG160 is about 20 years old. It alway frustrated me because of the air or lack of air in the line. This new pump gets a thumbs up. I'm 74, and was not the sharpest nut on the thread. I watched some YouTube videos on this product, consulted with a friend. If I can install this anyone else with limited skills can. Your product does the job.

### ⭐⭐⭐⭐⭐ Works good
*by T***S on October 22, 2023*

Nice quality, installed easily, everything fit like factory. Good value, sturdy , holes lined up on the engine.
