Proper sink drain??

[Jon Errickson]

This looks goofy to me (but i'm newer to this). Is this a proper sink drain?

[Jerry Peck]

Nope, that is a glorified 'S' trap, and 'S' traps are not allowed.

It's also a not-allowed 90 elbow at the bottom there.

I really like the way they wrapped that supply around the drain, cute.

Rube Goldberg would be proud.

Thanks Jerry... BTW it's the same house as the weird roof. there were quite a few other things too, of course.
