Is it effective?
I am not happy with the longevity of the knobs after a couple of years of use, and I need a screwdriver to turn the screw that secures it to the valve to turn open and close the valve sometimes.
Is there a PDF of the manual?

Is it possible to hook an oil injection into the system?
It depends on the type of oil/dye injector and the service port has non standard threads.
