ng

Pump fills with water, and leaks oil on to my patio and driveway. Unloaded valve hardly works, have to squeeze trigger to start it and it stalls if you try to idle the engine down. I bought this one because of the cat pump and it has let me down. Less than a year old. Talked to the repair shop Simpson directed me to and they said don’t bother bringing it to them.

Nice

Just received this last week. very nice quality of packaging and materials. Only problem i had with it was the quick connect ball joint for the pressure washer hose were stuck and could not get the hose to connect. Bought a new one and replaced it. I did have a lot of trouble starting it after releasing pressure, putting 91 octane gas. Oil and pump oil were filled, hose was connected,as well. After 20 minutes or so trying to get it to turn on i was able to turn it on. Sounds nice, ran it for a car wash test and ran flawlessly.Only thing is this machine is definitely a dancer which worries me since i know vibrations lead to engine and pump failure.Only used it once and im looking forward to use it for longer than a year. will be tying it down to a trailer so it doesnt shake so much. Other than that its a nice machine, only time will tell with the quality of this product.

Super Excellent Pressure Washer

I bought the Simpson 4200 PSI 4.0 GPM machine a couple months back. It was great, but was way too powerful for my application (it is a beast!). I sold it and purchased the ALH3228-S. It is simply a smaller version of the first one I bought. A mini-beast. Excellent quality machine, works flawlessly. Love the Honda engine (GX is a top of the line Honda engine) and the Cat pump (also a top quality brand/pump). The combination of the two on an aluminum frame is excellent. I will never buy any other pressure washer, only a Simpson. I added some cam-style brakes to keep it from bouncing down the driveway when I use it and replaced most of the steel bolts with stainless steel bolts. Make sure and buy the Simpson Pump Guard for longer storage, like over the winter. This will help the pump to last much longer.

Solid pressure washer

Working flawlessly. I am used to a longer hose for most jobs. This thing just keeps on humming. I notice the pump does get pretty hot so I do try to let it cool down periodically. The Cat pump does have a reputation as a commercial workhorse so no need to worry. The aluminum frame is very nice and you will notice it when hoisting it in and out of a vehicle.
