That separator looks like it's for the slide above or the Bode door. My configuration is so different that it would be hard to compare, but the water separator can be tossed in the garbage when it's in an air line , but yours appears to be in a mono block and wouldn't know which ports do what and what you can and can't block off or around. I have removed a few of these around my coach when they burst and regularly drain my tanks of any water instead of replacing them. no problem over several years. Is your set up original ? Our coaches were built months apart and have a real different air set up
