ABSTRACT:
A twist drain has a cylindrical twist drain element which is mountable on a tail piece and has a holding member and a rotatable member which rotates between open and closed positions to permit and interrupt a flow of fluid through the twist drain, a thread provided between the holding and rotatable members to rotatably connect them with one another, and a seal which prevents penetration of debris and foreign matter to the thread.
