Internal drain hair and debris straining assembly

A method, comprising:

• inserting a basket assembly into a drain flange, wherein the basket assembly comprises:
• a basket body surrounding a hollow core, the basket body comprising a plurality of openings configured to filter fluid to entrap debris;
• a first flexible rib positioned at a top end of the basket body having a diameter greater than a diameter of the basket body;
• and
• a second flexible rib positioned at a bottom end of the basket body having a diameter greater than the diameter of the basket body, the second flexible rib being configured to compress against an internal diameter of the drain flange and fold upwards when the basket assembly is positioned in a drain flange to form a seal between the basket assembly and the drain flange;
• and
• inserting a pop-up assembly into a top aperture of the basket assembly, wherein the pop-up assembly comprises:
• an interference ridge positioned at a bottom of the pop-up assembly, the interference ridge comprising a plurality of projections that project radially from the interference ridge that contact and form an interference fit with at least one inner wall of the basket assembly to retain a vertical position of the pop-up assembly relative to the basket assembly;
• and
• a pop-up base positioned below the interference ridge having a diameter less than a diameter of the interference ridge;
• wherein the pop-up assembly is configured to form a water-tight seal with a basin when the pop-up assembly is moved from an open position to a closed position;
• and
• adjusting the vertical position of the pop-up assembly relative to the basket assembly by pushing or pulling on the pop-up assembly.
