Hi, I started pressure washing in 05 and only used it about 10 times in a town that had a population of 3,000. Now living in a city of 34,000 and it is summer of 06. Just decided to make a living out of it and support my wife and soon to be new baby girl in october.Learning as i go but gaining information quickly from searching your written experience.I am 21 and my partner is also my brother who is 20. I now own a cold water 3700psi with 4.0gpm ar pump(home depot) but waiting for the money to invest in a good hot water trailer mount.
