Where can you find sizing tables showing the WFSUs for residential fixtures?

Sizing tables that display the Water Flow Supply Units (WFSUs) for residential fixtures can typically be found in local codes. Local codes are developed by municipalities or regions and are designed to comply with specific regulations and standards that govern plumbing systems within that area. They often include guidelines on fixture sizing, which encompasses the WFSUs necessary to ensure adequate water supply for various fixtures like sinks, toilets, or showers in residential settings.

Although manufacturer specifications, industry guidelines, and installation manuals may provide useful information regarding products and fixtures, local codes are the primary authoritative source for understanding what is required to meet compliance in a specific jurisdiction. These codes ensure that the plumbing systems are both safe and effective for the community’s needs, allowing for the proper flow rates and pressure levels necessary for efficient operation.
