Hi - I have a double sink and I'd like to re-plumb the drains. The current plumbing makes it difficult to store anything in the cabinets underneath, so I'd like to do what I can to make that better (without sacrificing anything).

As it stands now, the traps (two) are right below the drains. After the trap, the pipes go to the back of the cabinet, then they meet in the center, and go down to the basement.

My question...what are the codes/best practices I should keep in mind? I don't know much about drain plumbing.

Does each side need it's own trap, or can they share?

Just after the drain reaches the cabinet, can I install an elbow, sending the drain towards the back of the cabinet, then put a trap in, and go down to the basement?

Thanks.

I have only one trap for both of my bowls. Below one bowl is a tee to the other bowl and the trap directly below.

You need to find out if NY requires 2 traps. It's not needed but some areas require it by code
Check into end outlet wastes or center out wastes for use on a single trap

You can use a continuous waste tying the two sinks together one trap. one pipe,, must be in 2 inch after the trap. also you can not offset a trap. post a pic that would help.
