Hey everyone! I'm diving into plumbing for the first time, and I just finished setting up my kitchen sink piping. I'm feeling pretty hopeful that I've done things right, but I'd love your input to make sure everything is good to go. Thanks a ton for your help! Check out my setup here: https://imgur.com/a/gdjHQBp

Don't forget to knock out that piece for the dishwasher hose. Just making sure everything's in order because that could cause some issues later!
Looks like you've done a solid job! Just a heads up though, the air valve should be moved a bit higher, and you might want to add a clamp to the dishwasher discharge hose to secure it. Nice work overall!
Be careful with that vent; it needs to be above the sink level. If the sink backs up, you could end up with water spilling into your cabinet. Got a roof vent after it goes into the wall?
The old setup from the builder had it just like this, and since it's an island, there's no roof vent.

Just ensure it's 4 inches above the horizontal branch, that way you won't run into flood issues.
