Agreed, this setup is definitely not ideal. If it was me, it would get put on my to-do list of things that need done, and then it would sit at the bottom of that last and never get done because other stuff takes priority lol

In other words if you’ve got the time and the desire to fix it, it is probably worth it. Doesn’t look like it’d be too difficult to cut the main drain pipe and plumb in a new one that is the correct height.. It will probably be fine though
