Review: Great Product, would highly recommend! - Great product and well built.

On this pump the parts are metal parts instead of plastic so the quality is really great. Also, parts are easy to find for this pump. it bolted right on perfectly with no issues at all. I would recommend this pump to anybody else.

### ⭐⭐⭐⭐⭐ Easily installed replacement for Simpson pressure washer OEM pump with very low pressure
*by J***S on September 5, 2020*

My Simpson pressure washer (3100 PSI, 2.5 GPM) has served me well over a number of years, but its water pressure had dropped to the point that made cleaning my driveway very difficult. After reviewing some Youtube videos, I saw that the pump could be replaced. This unit is an exact OEM replacment for my unit, and the new pump restored the original capability to clean. Some time after I originally purchased the washer, I bought a surface cleaner, but I could not get it to clean concrete surfaces with mold, mildew, stains, etc. After I replaced the pump, the surface cleaner works well, and this attachment really speeds up cleaning my driveway. The pump is fastened to the gasoline engine with four allen key metric bolts that were somewhat stuck, but a little leverage on the allen key loosened them. The rest of the replacement was easy. Note that there is an alternative, less expensive approach to pump replacement: Ebay sellers provide new seal and valve kits to allow rebuilding the original pump, but I didn't realize this until after I had replaced my pump. When I disassembled my pump to see why it failed, I found that the water seals were worn and the valves had worn out; so a seal kit + a valve kit for a total of about $60 would likely have restored the original pump.
