Review: Exact fit and easy peasy - It was nearly six months after I purchased this before I got around to changing it out. My Simpson Power Washer was new and I had used it only one time in fall. I tried to clear out the water in the pump when I was done and put it away, but I did not use the antifreeze kit that is small pressure can and that cost me the pump. The next time I went to use it, the winter cold had frozen remaining water in the pump and that made it totally ineffective and lost all pressure. I was pleased to find this and ordered it. The repair shop wanted close to $250 to examine the unit and I had to drive an hour just to drop it off so this replacement part was a much more desireable option. I didn't know what to expect until I replaced it. It took me less than 10 minutes to put the new pump on. Four bolts and the original slid off the keyed shaft, I then slid the new pump on the shaft with attention to aligning it to the key and tightened up the bolts and done! Totally repaired and very happy with this part and ease of repair.
Review: The pump will fail with out water. - I purchased this to replace the original pump on my Simpson pressure washer which was almost new. The pump works great and is the same as on the original pressure washer. I would caution that the pump works great as long as the water is turned on. The pump is of a very good quality but has plastic valves - if the water stops the pump heats up very quickly and the plastic valves just melt and the pump no longer functions. This was my experience - the water stopped and the valves melted. I purchased the entire pump since just the valve portion was not available.

## Features

- Extend the life of your pressure washer: Save money by replacing your pump instead of buying a whole new power washer. This easy-to-install kit is great for power washers that can support 3200 PSI at 2.8 GPM to wash walls, sidewalks, vehicles, and more
- Compatibility: SAE standard bolt pattern fits many gas pressure washers with horizontal engines. To ensure compatibility, be sure to match engine orientation, PSI, GPM, engine shaft diameter, and current pump inlet and outlet connection
- Adjustable power: Pump includes PowerBoost Technology that delivers higher pressure at the nozzle for a more efficient cleaning experience; There is also a hand turn knob that lets you reduce power at your convenience for tasks that require lower pressure
- Know when to change your oil: The sight glass and advanced oil seal technology eliminates the need for a dipstick. With visibility to the oil level and the oil itself, you can easily see when oil levels are low or if water has clouded the oil

### ⭐⭐⭐⭐ It works
*by R***7 on June 29, 2021*

I bought this to replace a AAA Pressure Washer Pump 8.7GA12 that came on my Simpson Aluminum ALH3225 Pressure washer. Install was super easy, four bolts off, four bolts back on. Works fine. I hope Simpson is reading as my original pump was/is still under warrantee and I was approved for a replacement back in October of 2020, it is June of 2021 and it is still not in. No amount of calling customer service helps because , well, it's not there fault or problem. All warrantee is handled by a third party. Remember that the next time you want to buy anything made by Simpson.
