= Fixture unit
{wiki=Fixture_unit}
A fixture unit is a measurement used in plumbing engineering to quantify the contribution of various plumbing fixtures to the overall demand for water in a building. This concept helps in determining the appropriate size of water supply and drainage systems. Each plumbing fixture (e.g., sinks, toilets, showers, bathtubs) is assigned a specific number of fixture units based on its typical flow rate and usage patterns. The fixture unit values are standardized and can vary by local codes or regulations.
