I think there is a metal hydraulic line that comes into the valve and to flip it that would have to be replaced. I don't have the splitter here in Ga with me. It is at my place in NC. That is the only photo that I have of it. I don't think it would be much of a problem to change. I tried to attach a PDF file of the owners manual last night but couldn't. I think I downloaded it from the Harbor Freight site.
