If the drain in your bathroom sink is rusty, corroded and the pop-up stopper no longer makes a good seal, replace it with a new drain yourself. With a few household tools, you can have a new drain in that sink in a couple of hours. If you're uncomfortable working with household plumbing, you may want to hire a plumber to do the work for you. But if you are the DIY type of homeowner, here are the steps to replace that drain yourself.
What You'll Need for This Project
- flat-blade screwdriver
- channel lock pliers
- small bucket
- rags for cleanup
From the plumbing supply store:
- bathroom sink drain kit with pop-up stopper
- plumber's putty (optional)
- putty knife (optional)
Removing the Old Drain
- Follow the rod (push rod) down that you use to open and close the stopper.
- Disconnect it from the flat metal plate (clevis) under the sink.
- Pull the rod up and out of the sink.
- Follow the horizontal rod (pivot rod) connected to the other end of the clevis plate to the small ball (pivot ball) located in the vertical drain pipe coming down from the sink.
- Unscrew the large nut that holds the pivot ball in the drain.
- Remove the nut, pivot rod and ball from the drain.
- Place the bucket under the P-trap to collect any spilled water.
- Unscrew the connector holding the P-trap to the drain pipe coming down from the sink.
- Unscrew the large nut holding the drain pipe to the bottom of the sink.
- Wiggle the drain pipe slightly to loosen the seal and push the pipe up through the sink.
- Once the drain pipe separates from the P-trap, remove the large nut and washer from the end of the pipe.
- If plumber's putty was used to seal the drain to the top of the sink, scrape it off with the putty knife and wipe the surface clean.
Putting in the New Drain
- Slide one of the large washers onto the drain pipe and push it against the drain. If the kit includes only one large washer, apply a small ring of the plumber's putty to the underside surface of the drain where it rests against the sink.
- Lower the drain pipe down through the sink drain hole.
- Under the sink, push the other large washer onto the drain pipe and up against the bottom of the sink.
- Before tightening the drain pipe to the sink, turn the pipe so you can see into the hole where the pivot ball will go.
- Push the large nut up onto the drain pipe and screw it hand-tight to secure it to the bottom of the sink.
- Lower the pop-up stopper down into the drain.
- Look through the hole in the drain pipe where the pivot ball will go and turn the stopper until you can see the small slot at the bottom of the stopper.
- Push the short rod of the pivot ball into the hole in the drain pipe making sure the rod goes through the slot in the stopper.
- Test this by pushing the long rod coming out of the pivot ball up and down. You should see the stopper move when you do this.
- Secure the pivot ball to the drain pipe with the large nut.
- Secure the clevis plate to the long rod coming out of the pivot ball with the clip provided.
- Put the new push rod down through the sink and secure the end to the clevis plate with the set screw.
- Adjust the clevis plate on the pivot rod and push rod until the push rod easily opens and closes the stopper.
- Push the large nut onto the bottom of the drain pipe followed by the large washer.
- Connect the drain pipe to the P-trap and tighten the large nut to secure them together.
Problems You May Experience
- Rust and corrosion can make the connectors hard to remove. If you can't loosen the connections by hand, try the pliers. If the connections still won't come off, you'll need a plumbing service like one from Stephens Plumbing And Heating Inc to come out and do the work.
