What is the minimum drain size required for a commercial laundry?

The minimum drain size required for a commercial laundry is 2 inches. This is specifically outlined in the Massachusetts Plumbing Code, which sets standards for the design and installation of plumbing systems to ensure adequate performance and safety.

A 2-inch drain is necessary to handle the significant volume of wastewater that commercial laundry equipment generates, such as washing machines and dryers. The larger diameter ensures proper drainage, reducing the risk of clogs and backups that can occur if the drain is too small. Additionally, a 2-inch drain allows for efficient flow, accommodating the peak discharge rates of multiple machines operating simultaneously.

In commercial settings, proper sizing of drainage systems is crucial not only for functionality but also for compliance with health and safety regulations. Having a correctly sized drain helps promote effective wastewater management and prevents potential plumbing issues that could disrupt operations in a commercial laundry facility.
