I recently tested the new AR630 and noticed a slight difference in performance between a 3/8" hose and a 1/4" hose. Based on Fluid Dynamics and Friction Loss, the result makes sense... However, I wanted to test the theory more to see if the size of your pressure washer hose really effects the performance of your pressure washer. I will test 3 different hoses side by side to see how they compare and let you know what hose I continue to use... ENJOY!!!
