A vortex flow regulator used in sewer catch basins to prevent overflow of the system from storm water runoff and to standardize the production of regulators. The hollow body of these flow regulators within a given range of regulators by the present construction have been found suitable for different size discharge orifice requirements. A flow regulator has been provided that is adapted to standardization of parts when built with only its discharge orifice needing change. The structure lends itself to mass production of flow regulators. Simple means for attachment of flow regulators within basin drain pipes has been provided.
