What is this pipe for?

Hi I noticed when cleaning this plastic pipe has come away from toilet. But looking inside it looks capped off anyway? Just wanted to check this is an old disused pipe as there is another copper pipe connected too? Thanks

It’s for an overflow, but as you have observed it is capped off.

Yeah, overflow capped off. They mostly overflow into the pan these days.

Thanks! I thought that was the case but google scared me into thinking I could flood my bathroom. Google not always the best haha

Google is right, you appear to have a siphon flush valve which is not the correct fixture to overflow into the pan so you will potentially flood the bathroom if the fill valve fails open.
