Hey Mark, pump question for you. With the machine I have been having my problem with i have a question. It has a general TSF 2221 pump on it and a 24 hp honda hot water with 120v burner and is set up for 6 gpm at 3500psi. My question is can I make it a 8 gpm? How much would I have to change? How much pressure would I loose? I use it mostly for flatwork.
