Outdoor Kitchen sink drain leaking - Reflection 312BHTS

[NYMSCamper]

Hello,
I took my camper out for the first trip of the season, went to dewinterize all the drains and my outdoor kitchen sink drain is leaking (almost directly under the sink) from the white pipe into the black pipe (forgot to take picture before putting into storage). Any Idea if these pipes just need to be replaced? I tried to tighten them but no luck. I am not even sure what the part names would be. Thanks in advance.

If the trap part froze and broke it will need replaced. I think all of these parts would be available at the local hardware store, take your parts in for a match after you figure out what needs replaced.

I went and took a picture of where it's leaking. I could unscrew the nut, but the other end feels like it's got lock tight or something and didn't want to come out. Thought I'd see if there's any more suggestions, as I don't want to force it and do more damage. Thanks.

That looks like a HepVo valve (waterless trap). See https://hepvo.com/installation-maintenance/ where's there's a link to the installation manual.
