Leaking back of Toilet

[CurtisO]

Are you absolutely sure that the leak is from there? I was at my daughter's yesterday looking at an identical situation but the leak was actually one of the bolt-holes in the close-coupled toilet just dripping onto the shroud of the toilet connector. I would definitely try and eliminate anotther possibility before attempting to remove a fixed inlet.

The big clue is that the water is "fresh" and clear as opposed to cloudy.

PS If you do go ahead with the replacement, I'd consider replacing the fixed connection with a looped flexi connector. This will make the final toilet fitting a whole lot easier. Also would recommend cleaning the painted pipe before doing anything else to ensure that you can get a good connection. You'll likely have to slice off some of the pipe achieve this simply

Second if I was to change the fixed connector to a flexi what is required to know what one to get?

There's no need, the fixed connection is better.

Before dis mantling it try pushing the black rubber bit in a bit more using a wide bladed screwdriver or back of a chisel
