I Been tuning my rodi machine just changed the filters and switched the hoses because the other one was extremely loud and this hose is a lot better but I was just curious as to my pressure? I usually run my machine with the flow closed but the psi is under 0 is it too strong and just going above 100 because when I open the flow it spins backwards but never goes from 0 to 100 just from bellow 0 backwards here are some photos of it open and closed.
