I am interested in purchasing one of your catch cans, but I am confused regarding the options. What is the difference/benefit between the single valve and the dual valve catch cans. Also, when ordering the single check valve can, your website asks whether or not we want a check valve [i.e. yes or no]. Please explain the differences.
In addition, the website lists the single check valve can as available in Synergy Green, but not the dual valve can. Is this correct?
