I work residential concrete using the classic 19" surface cleaner with a pressure pro 4040, at 4 gpm and 4000 psi. Age of concrete 4 to 14 years and I think it is very poor.
Like many others on the forum, I have excessive sand from the concrete in the rinse water.
Various nozzles I used are 25 degree 2.0, 2.25 and 2.5.
A suggestion I like is reducing pressure to 3000 using the unloader and leaving it there.
I'm told I may loose a little flow but that it won't hurt the pressure washer.
Am I on the right track?
