This is a valve inside that controls the flow of water to my outdoor spigot (which has its own valve). It's leaking. I was able to temporarily fix the leak by repacking the nut but that's a temporary fix because the leak starts again if i close the valve (plus the nut has a crack).
Is this something I can replace myself? I notice a square shaped bottom (under the nut which has 6 sides) which makes me hopeful I can unscrew that? If so, what am I looking for? Any idea where I can get a replacement or what it's called?
Or would I have to re-weld a whole new valve on? In which case I guess I need to call a plumber.
