Devices and Methods for Optimizing Flow Through Drains

A drain insert is described that provides a valve that prevents backflow of objects and materials through the drain inlet and which has an internal wall with a convex curvature. This convex curvature, which can be elliptical, provides improved fluid flow rates relative to straight walled, cylindrica...

description	A drain insert is described that provides a valve that prevents backflow of objects and materials through the drain inlet and which has an internal wall with a convex curvature. This convex curvature, which can be elliptical, provides improved fluid flow rates relative to straight walled, cylindrical configurations, permitting small diameter drains to utilize the drain insert while meeting IAPMO flow rate requirements.
