I am looking into upgrading to a 3500psi 8gpm machine, however I want to make sure it’s the right choice before I pull the trigger. I tried searching for some sort of chart that compared many different levels of PSI and GPM and how long it took to clean a certain amount of SQFT and what they were cleaning. Having this data would allow me to justify the cost of buying this machine.
I also want to throw in a second question and that is how someone would supply water to a 8gpm machine. I’ve seen water reservoirs that get pretty massive but the most common thing that I’ve seen is a buffer tank with client water filling it at the same time. If anyone has this kind of setup how big is your tank, and how long can you run it before having to let it fill up again. I appreciate all feedback.
