Q: What is minimum psi

5 months ago
1 Answer
  • A: The SIMPSON 3,600 PSI 2.5 GPM Gas Cold Water Aluminum Professional Pressure Washer operates at a maximum pressure of 3,600 PSI. Still, it can be used at lower pressures depending on the accessory or method used. There is no official "minimum operating PSI" specified by the manufacturer for the machine itself, as its pressure output depends on engine speed and the pump.

Most Helpful Favorable Review

All you need

I have used many gas washers and find the Honda/Simpson combo the most consistent and powerful combination for the money. You can spend more, but for the ranch/farm home user you dont need anything more. Likely it is a bit too powerful for those new to powerwashers, I highly suggest practicing before you end up damaging your home, fence driveway etc. One negative about shipping: the main problem is the oil that is shipped with the unit. The oil bag was holed and leaked all over the inside of the box, quite a mess but no real damage.

Don't Buy Simpson Pressure Washers

4 years ago
I Purchased a Simpson ALH3425-S pressure washer from TSC. Less than two years with limited use the pump stopped working. The pump was maintained properly and drained after use. I took the pressure washer to an authorized Simpson repair shop and they contacted Simpson to get ok for the repair, they told the repair person the pump was no longer under warranty although the Simpson and TSC website shows 5 year warranty on AAA pumps. It was going to cost so much to make the repair the repair person told me I would be better off purchasing a new pressure washer. I also contacted TSC, they were no help and did not stand behind the product either. Very dissappointed in TSC. I do not know why they would carry a product from a manufacturer that will not stand behind their product. The warranty they have listed for Simpson pressure washers is basically useless. I have since purchased a Generac and have no problems. The only reason Simpson has good reviews on their website is they remove the ones they do not like, they removed mine. Don't buy a Simpson product

Well worth owning

5 days ago
[This review was collected as part of a promotion.] Absolutely love this model which I have wanted for awhile now. The Honda GX200 might be the smoothest starting motor I have owned on any pressure washer. Along with the stylish aluminum frame this thing is awesome. Highly recommend!!!
