i just got my first rep in a noob 116600 v2 from trusty and got a question or two. it has a black ceramic bezel and I want to replace it with a blue one. they don't make them so I figured I can use one off a 16610LV is that correct? also, Is the he valve actually functional and how you can get it tested? would a pressure test work? I'm wanting to start building this thing and this is my first decent quality rep so any help would be greatly appreciated
