Just curious - I see some impressive numbers on this website when it comes to pressure washers and their G.P.M's. I read about somewhere the average municipal water supply is only about 5 G.P.M. in residential areas. So I tested my hose - and it turned out to be about 4 G.P.M. So is it practical to have pressure washers much beyond 3.5 G.P.M. for residential use? Are the larger numbers I see being posted - for commercial work with higher output source of water?
