How many fixtures can be served by one flushing device?

A flushing device, such as a flushometer or a toilet tank, is designed to serve a defined capacity of plumbing fixtures efficiently and effectively. In plumbing codes and standards, the typical guideline is that a single flushing device is intended to serve one fixture at a time. This ensures that the water supply and drainage systems function optimally without overloading or causing malfunctions.

When multiple fixtures are connected to a single flushing device, it can lead to inadequate flushing, inefficient waste removal, and increased risk of plumbing issues, such as clogs or backups. Therefore, limiting the service to one fixture per flushing device helps maintain a reliable and efficient plumbing system, adhering to safety and performance standards critical in plumbing installations.
