Replace your sink flange when needed.
The sink flange is the circular part of the drain that surrounds the drain opening. These are most commonly made of metal, but PVC is also a common choice. Replacing a bathroom sink flange involves disconnecting the plumbing beneath the sink so you can pop the flange out from underneath. Putting down a layer of plumber's putty when replacing the bathroom sink flange will ensure that your drain connection will stay watertight.
Instructions
1. Position yourself underneath the sink. Place a bucket beneath the curved portion of the plumbing underneath the drain. Loosen the two couplings at either end of the trap with a pair of pliers. Remove the trap and empty the water into the bucket.
2. Unscrew the jamb nut with the pliers. The jamb nut is the large nut located directly beneath the sink. Remove this and the rubber washer from the tailpiece by sliding it off.
3. Unscrew the tailpiece, the straight portion of the pipe directly beneath the sink, by turning it counterclockwise.
4. Tap the underside of the sink flange with a rubber mallet until it pops out in the sink above.
5. Take the new flange and turn it over so that it is upside down. Roll out a bead of plumber's putty and press it into the flange. Turn the flange back over and press it into the flange opening at the bottom of the sink.
6. Hold the flange with one hand. Screw in the tailpiece to the underside of the flange with the other hand. It may be easier to have an assistant hold the flange in place if this is a large sink.
7. Slide the rubber washer and jamb nut over the end of the tailpiece. Tighten in place with the pliers.
8. Wrap the pipe threads on the tailpiece and the sewer inlet (the pipe sticking out of the wall) with plumber's tape. Slip the p-trap back into position between the sewer inlet and tailpiece. Tighten the couplings with pliers.
