A double sink vanity typically features two separate faucets, dual drain lines, and integrated waste and vent piping. The plumbing diagram illustrates how water supply and drainage connect beneath the vanity, ensuring proper flow and venting to prevent gurgling or backups. Proper vent placement avoids pressure issues, while strategic drain positioning minimizes water pooling and corrosion risks.

The diagram highlights essential elements: two shut-off valves under each sink, a shared waste stack with individual traps, and vent pipes branching off to maintain atmospheric balance. Supply lines are routed to individual sink faucets, with minimal cross-connection to reduce contamination risks. Proper slope and p-trap installation ensure clean drainage and odor control.
