TL;DR
A lavatory pop-up assembly is the drain mechanism in a bathroom sink that raises and lowers the stopper through a lift rod behind the faucet, a pivot rod entering the drain body, and a clevis strap linking the two. It is among the most frequently serviced parts in residential plumbing: hair wraps the pivot and stopper, the pivot-rod gasket weeps under the sink, and the clevis screw slips so the stopper stops sealing.
What it means
A lavatory pop-up assembly is the drain mechanism in a bathroom sink that raises and lowers the stopper through a lift rod behind the faucet, a pivot rod entering the drain body, and a clevis strap linking the two. It is among the most frequently serviced parts in residential plumbing: hair wraps the pivot and stopper, the pivot-rod gasket weeps under the sink, and the clevis screw slips so the stopper stops sealing. Repairs are hand-tool work, and full replacement assemblies in PVC or brass cost little compared to the faucet they accompany.
