What is the maximum number of showers that can be connected to one drain?

The maximum number of showers that can be connected to one drain is based on plumbing codes, which are designed to ensure proper drainage and prevent issues such as clogging or backflow. According to standard plumbing practices, it is typically acceptable to connect up to six showers to one drainage system. This limit helps maintain an adequate flow rate and minimizes the risk of overwhelming the drainage system.

When determining the maximum capacity for drains, factors such as the size of the drainage pipe and the expected water flow from each fixture play a critical role. Each shower contributes a specific amount of drainage load, and having too many showers connected to a single drain can lead to inefficiencies and problems with wastewater management.

Therefore, the correct answer of six reflects a balance of these considerations, ensuring that the plumbing system remains effective and compliant with overall regulations.
