I recently purchased a used and old Gravermax SC device which I renovated and changed the tubes for, in my opinion it works properly but the function of the foot pedal is not clear enough to me, or the difference is not significant enough whether I press it or not.
Is there a clear diagram for the pipe connections of the Gravermax because the ones in the manual are not clear enough.
Also, is it recommended to clean the rotary valve already?
