You`ll enjoy this washer. In addition to helping you wash your vehicles, it`s fantastic for lots of stuff around the house.
If you want to decrease the PSI but still keep the GPM, simply opt for nozzles (tips) with larger orifices. Consult a nozzle chart,
like this one, to determine the orifice size required for the pressure you want. GPM will remain the same. When cleaning just tires, opt for the green nozzle, and if they`re off the vehicle, use a yellow nozzle for kicking butt and not taking names!
The washer will start more easily if you start it with the trigger pulled.
Don`t let it run in bypass mode (trigger not pulled) for more than about 60–90 seconds.
A chief noise offender on this one is caused by the vibration of the frame where the top portion and bottom portion connect. I believe if I could silence that noise, the washer would sound good.
Think of it more as a 3000 PSI washer than a 3100 PSI washer. Generac squeezes that extra 100 PSI from using a shorter 1/4" hose. You`ll probably want a 3/8" 50` hose, which will drop the PSI from 3100 to 2950–3000. GPM will remain the same.
Soaping with the black nozzle on things is not very effective or fun compared to using a foam cannon.
Enjoy and have fun!
