What is the required trap size for a clinic sink?

The required trap size for a clinic sink is 2 inches, which aligns with common plumbing codes and standards for similar fixtures. A 2-inch trap is suitable for the type of drainage needs a clinic sink would have, ensuring adequate drainage while preventing clogs.

A trap size larger than 2 inches, such as 3 inches or 4 inches, would be unnecessary for a sink application, as these sizes are typically reserved for larger fixtures or drainage systems where higher volumes of waste are expected. Conversely, a 1 1/2-inch trap may not provide sufficient capacity for draining a clinic sink, especially if multiple sinks are in operation simultaneously, potentially leading to drainage issues. Thus, a 2-inch trap is optimal for balancing effective waste management and compliance with plumbing regulations for caliber sinks used in clinic settings.
