### ⭐⭐⭐⭐⭐ Great pump
*by A***N on August 6, 2025*

This was purchased got my husband’s pressure washer works great

### ⭐⭐⭐⭐⭐ Great pump, extremely powerful
*by A***Y on July 25, 2024*

I don't usually write reviews, but this pump has been GREAT.. so far anyway.. I'll keep this short.. I bought this pump to replace a 15-20 year old pump on a Devilbiss pressure washer that finally gave up the ghost.. I needed a pump that was powerful, and one I could get fast, well this one fits those needs.. I'm using my pressure washer to strip as much old pant off the walls of my concrete pool. For the price of this pump I thought, who cares if it lasts, as long as I get the pool done. I can't say anything for longevity, but for a couple days in a row now I've used this pump on full power and non-stop. I've only stopped to give my hand a 30 second rest, move to another spot, or my power washer has run out of gas. I don't have a pressure gauge, but this pump is EXTREMELY POWERFUL. So far, I couldn't be more satisfied with this pump. I hope this helps.. btw, the 4400 psi pump is not the same pump as the 3600 psi pump. They look the same, but the 4400 psi pump is infact stronger...

### ⭐⭐⭐⭐ Original fit
*by D***E on April 9, 2025*

The media could not be loaded. Works great for DeWalt 4200 psi pressure washer. Very easy to install
