A check valve mechanism for use with a vertical drain pipe comprises a connector portion for supporting the check valve mechanism with respect to the drain pipe, and two flaps, each being an ungula of a cylindrical tube. The flaps are pivotally connected to the connector portion, so as to be displaceable between a closed position in which the flaps are against one another such that peripheral portions of the flaps are collinear at a connection line to obstruct the drain pipe, and an opened position, in which the flaps are away from one another to allow liquids/solids to pass through the check valve mechanism and the flaps.
