Is it ok to lower the pressure on my machine by choking the ball valve, which is before my trigger? It is convenient but I don’t know if that will cause damage to my pump.

Ryan, what are you lower psi for? What you’re saying here is not advisable.
My machine is 3000psi 8gpm. I use a jrod for my nozzle. However I don’t like to use the full power especially around windows and doors ( I’m speaking of the low rinse nozzle ). So to lower the pressure I have been choking the ball valve. It seems to give me the pressure I want and it is very easy to control. If that is not recommended I was thinking of choking the throttle on the machine. I should also state that today was my first day with a 8 gpm machine so I am learning to work with it. I have always used 4 gpm in the past. If none of these ideas are adviseable should I just stand far enough back from what I am washing to not cause damage and just keep the pressure at what it is?

Choking the ball valve reduces gpm…you don’t want that. Throttling down reduces gpm…you don’t want that either…Go to a larger orifice nozzle. We use 1540’s & 1550’s…this is a 15 degree #40 or #50 size orifice…works great!
