Pressure Washer Nozzle Calculators
Single Nozzle Calculator
Enter your pump's flow rate in GPM and the desired pressure in PSI to calculate the required nozzle orifice size.
Surface Cleaner Nozzle Calculator
Enter your pump's flow rate in GPM, the desired pressure in PSI, and the number of nozzles on your surface cleaner to calculate the required nozzle orifice size.
We recommend sizing your surface cleaner tips for around 2500 psi. Cleaning at pressures above 3000 psi can greatly increase the likelihood of etching the concrete.
Nerd Tip: A 25 degree (green tip) nozzle will most commonly be used with your wand to clean the edges around the surface cleaning areas. It’s a good idea to size your green tip nozzle for the same pressure as your surface cleaner to give a consistent clean result.
