Does double sink with disposal need two P traps?

Normally, these double tees are used for adjoining bathrooms, so you can have a sink on each side of the wall and share the same stack.

Does garbage disposal need a separate drain?

Think of it like the ring that connects the two pieces together in one unit, though it is positioned slightly down so water can run unimpeded down the drain thanks to its sloped design.

Most garbage disposals are mounted with 3”-4” of clearance under them, so measure your sink carefully when ordering one.
