Start by adding plumber’s putty to the underside of the basket strainer and fit it into the drain hole at the bottom of the sink. Then, tighten the nut with a basket wrench to secure it in place. You can then fit a brass tailpiece onto the bottom of the basket strainer, reconnect the drainpipes, and you’re done!

Apply Plumber’s Putty: Roll a rope of putty about the thickness of a pencil and press it evenly around the underside of the new drain flange (that’s the circular ridge around the drain piece). Also, apply the tape to the threads of the drain pieces. Insert the Drain: Position the drain in the sink hole and press down firmly to create a seal.
