Contractor installed this convoluted p-trap + elbow for the washer, and I’m not sure if it’s up to code. Can you confirm and more importantly explain why or why not it’s compliant?

When you do get that connection … go the extra step and install a ‘backwater prevention valve’ … it’s a giant one way valve that is attached to the main drain line as it leaves the house.
It allows water to always easily flow out but if it ever happens that water back flows into your house for some reason … the valve will stop any flow from entering your house.
I’ve always planned to get one but my situation is too difficult to install one.
That does seem pretty obligatory. We have the same thing on our irrigation (don’t want irrigation water backflowing in to the drinking water, and also it’s required).
We are at the top of a hill and everything flows down from us to the entire neighborhood, so that is another good check on the issue.
