My toilet incoming water valve is not shutting off completely after the flush is complete. As a result water slowly fills the bowl until it overflows into the overflow line.
I believe the valve just needs to be replaced, but I can't figure out which is the right valve.
The toilet is 12v, and the exit pipe goes down thru the floor, not the back wall.
On the inside of the service area I see "LF 210 ER" embedded in the casing of the body.
The valve has a top plastic piece that snaps off and this has "MicroPhor Inc 539 Willits CA".
This makes me think I have a Microphor 210, but everything I read online talks of this toilet being air activated. I don't see any air lines going into my toilet.

Any suggestions on what toilet I might have?
