So I am pretty sure I understand nozzle sizes now, as this site was helpful in explaining a lot about pressure washing nozzles http://www.ultimatew...ay-nozzles.htm . So my new surface cleaner, Whisper Wash Classic came with 2502 nozzles in the bar. Correct me if I am wrong but those are way to small for my machine 5.6 GPM 3500 psi. One they are going to overwork my machine and two put way to much pressure on the concrete. If I want to lower the pressure to about 2500 psi I would want to use like a 2507 nozzle correct?
