What is the best gpm and psi pump for concrete and brick? I want higher gpm but don’t want to lose the psi.
You don’t need super high PSI for brick and concrete, 2500 is plenty. I think you can get a way with 2200psi/5gpm with a GX390, horsepower-wise. You may do a bit better with a 440cc DuroMax power-wise.
If you are surface cleaning concrete, get the highest GPM you can afford. When I jumped from 4-5.5 it was a big improvement, then 8 was a real game changer but that requires a v-twin.
