This is a shower diverter stem from a Kohler 3 valve tub and shower manifold. It is leaking in multiple places, and replacing the washers/gaskets didn't help it. The metal is damaged. I have looked in every plumbing supply store locally that I can find, and nobody can seem to match up this stem with something else that will work. I even bought a "closest recommendation" from one of them and there was too much threading for it to screw in and work properly. If any of you could find a similar or exact working part to this one that I could purchase online, you can consider me your best friend for life. Someone please help??
