Step 3 · Disconnect Pop-Up Drain Linkage

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

Locate the pop-up drain's lift rod mechanism. You will see a horizontal pivot rod connected to the drain pipe with a clip. Squeeze the spring clip to release the horizontal rod from the lift rod strap. Then, using channel-lock pliers, unscrew the retaining nut that holds the pivot rod in the drainpipe and pull the rod out. The pop-up stopper can now be lifted out from the top of the sink.
