Review Posted 04/26/2020
I have this pump on my 4200 psi Dewalt washer. I have used it every weekend in good weather for about 7 or 8 years and it still works and even looks like brand new. I will never buy another pressure washer unless it has a Honda engine and a Cat pump.

3 1/2 Years Old

Review Posted 06/03/2018
Love this, was a replacement of a smaller pump that burnt up. Put this one and now the motor was a little too small just a little, so put a bigger motor on it - 13 horse. Had a lot of people ask what kind of chemical I put on the driveway to make it come off so easy. I just laugh and say I did not put anything on it it's all pump that is taking it off. This pump is a monster 3 1/2 years old now and still no problem.

I plumbed the pump and installed it to my engine. It is only putting out around 1000 psi instead of 4000 psi. I took it to a shop.

Review Posted 10/26/2013
Last year our pump went out and we tried to replace it with this pump but couldn't find it. That pump failed after one year...
CAT builds a better pump, we should have doe this before and saved the money spent.
