Morning fellow inspectors! During an inspection, I saw this configuration underneath the kitchen sink. I wasn’t sure if the installation was correct or incorrect. Please advise, thanks.
Are you asking about the trap?
It is fine.

I don’t see an issue with the DWV drain.
The dishwasher drain is not installed properly. The UPC requires a vacuum breaker installed on the countertop. The IRC requires a high loop. The discharge piping from the dishwasher must be installed tight to the countertop, fastening place before discharging into a garbage disposal or tailpiece.
P2717.2 Sink and dishwasher.
The combined discharge from a dishwasher and a one- or two-compartment sink, with or without a food-waste disposer, shall be served by a trap of not less than 1½ inches (38 mm) in outside diameter. The dishwasher discharge pipe or tubing shall rise to the underside of the counter and be fastened or otherwise held in that position before connecting to the head of the food-waste disposer or to a wye fitting in the sink tailpiece.

Yes. It didn’t look accurate. Kinda threw me off.
The counter top has a vaccum break installed. But, dishwasher drain hose wasn’t high looped
What would it look like to you if you straightened out the fittings?
Then,how did it drain when you filled water into the sink and let it rip. Performance is the greatest consideration in calling these things out.
When water has to change direction, it is going to back up. So you need to see if it flows ok.
I can’t see, where does the disposal drain go?

It looks like a p-trap to me. It’s fine
Look in the rear if picture you can see a clear hose coming from air gap top of sink,
Where does the disposal drain connect to the main drain?
Couldn’t see it
