Manifold/Pump Assembly
By Erskine F. 
Pell City, Alabama
Purchased 05/14/2018 | 
Review Posted 06/20/2018 
After pricing the manifold only I located this part that includes the manifold and pump. It was 1/5 the price, easier to install and works great.

Not Very Durable
By Shawn C. 
Moncks Corner, South Carolina
Purchased 05/25/2017 | 
Review Posted 07/29/2017 
I have two of the DeWalt machines that take these pumps, both approximately 2 years old used commercially- which they are recommended for. I have replaced two on one machine and one on the other. The warranty covered two pumps and I purchased the other.

DeWalt would not cover one due to a cracked manifold. The manifold was cracked due to over tightening by the authorized shop. O rings blew, shop replaced, I picked up- still leaked same location. Shop cracked manifold upon replacing rings and left me with the bill. The pump performance however is great while it lasts.

The Factory Warranty covers defects in materials and workmanship, but it doesn't cover wear & tear or lack of maintenance. That being said, you may want to give the folks at Simpson (the makers of AAA pumps) a call at 877-362-4271to let them know about your situation, and see if there is another Factory Service location in your area that may provide you with better service.

For greater durability you may want to try a CAT Brand triplex pump if they have one that will match up with your pressure washer's mounting brackets & shaft.

Not Sure On Quality of AAA Pumps
By Melvin D. 
Plummer, Idaho
Purchased 06/25/2017 | 
Review Posted 07/21/2017 
Maybe the AAA pressure pumps are a quality pump and I just happen to get 2 bad ones. I will respond futher when I find out how they stand behind them, that is far more important than a faulty product now and then. Any company out there is gonna have a bad one slip thru now and then.

AAA pumps are one of the Simpson family of brands. Their Factory Warranty covers defects in materials and workmanship for 5 years, but it does not cover wear and tear items or improper installation.

Your file shows we are helping you and Simpson resolve the issues with your pump. We appreciate your business and apologize for any inconvenience.

I Ordered The Correct Assembly
By Glenn F. 
Fort Myers, Florida
Purchased 11/14/2016 | 
Review Posted 12/27/2016 
The situation always helps when the customer (ME) orders and receives the correct part. The routine of replacing parts goes smoother when DIRECTIONS are followed!

I received the assembly and replaced it in the field. Had to go buy some anti-seize at a local auto parts. Then did a job in the same breath. Thanks Pressure Washer Direct. You made my day THAT day.
