Abstract: A floor drain adapter comprises a floor drain cover having an opening communicated to the floor drain and an elbow disposed on the cover and terminating in an open end. A rubber collar is provided about the open end in a manner to define an opening to receive one or more rubber sheathed drain hoses and in which one or more drain hoses are maintained in position by frictional engagement with the collar and with one another when more than one drain hose is present, even when a fluid, such as water, is drained through the hose(s) at high rates. The drain cover typically includes drain slots to drain a fluid on the floor and may include a vent opening above the cover as may be required by building code.
