Replacing a ridget water intake pipe for a toilet with a flexable hose

[David s]

I'm trying to replace the intake pipe for a toilet. The current one is ridget pvc piping. I'm trying to swap it with a flexible hose to install a bidet.

I can disconnect the pipe from the toilet, but I can't unscrew it from the shutoff valve. Am I meant to be able to dismantle it or is it just a rip it out type of thing

Hard to say without a picture.

What country are you in and what sort of bidet are you trying to install?
