Anyone in the PPOT Brain Trust know anything about this type of pressurized reservoir toilet. The white dot in the center of the hex-looking black nut thing is the valve. It was sticking, so I put some 3-in-1 oil on it and now when you flush it opens and closes about a zillion times and you have to hold it down until it fills. Can I get replacement parts, HD doesn't seem to have any idea. No markings as to manufacturer. Or should I just buy another toilet?
Thanks in Advance.
Edit: Upon closer examination, the tag to the right says Kohler, so that gets me started.
