How to Replace a Bathroom Sink Drain in 7 Easy Steps

Hey, are you having trouble with an unreliable bathroom sink drain in Vancouver? Could it be leaking, clogged, or simply unsightly? I totally understand; I’ve been there too. But here’s the good news: repairing your drain is easier than you might think!

I’m here to walk you through the process step by step. No plumbing experience? No problem. With a few basic tools and some know-how, you’ll have that drain replaced in no time. So, let’s roll up our sleeves and get started!

Gather the Necessary Tools and Materials

Before you replace that old, leaky bathroom sink drain, ensure you have all the right tools and materials. Trust me, there’s nothing worse than getting halfway through a plumbing project only to realize you’re missing a crucial piece. I’ve been there, done that.

Safety Precautions

Safety first, my friend. Throw on some safety glasses to protect those peepers from any flying debris or splashing water. And don’t forget a pair of gloves to keep your hands safe from sharp edges on the drain parts. Take it from someone who’s gotten a few cuts and scrapes over the years – it’s worth the extra precaution.

Preparing the Work Area

Clear out that cabinet under the sink and give yourself plenty of room to work. Lay down a towel or drop cloth to catch any water spills or stray bits of plumber’s putty. Grab a bucket or large bowl under the drain – this will catch any water dripping out when you disconnect the P-trap and drain pipes. Have some rags or paper towels handy to wipe up any messes. 

And if you want to make your life easier, invest in a pair of channel-type pliers – they’ll make loosening those stubborn nuts and bolts a breeze.

Remove the Old Sink Drain Assembly

Now that you’re all set up, it’s time to bid farewell to that old, crusty sink drain. But before you start yanking things apart, take a deep breath and let’s walk through the steps.

Disconnecting the Pop-up Stopper

See that little knob or lever sticking out the back of your drain pipe? That’s the pop-up stopper mechanism. Start by disconnecting the pivot rod nut that connects the lever to the drain stopper. Use your channel-type pliers to loosen the nut, then pull out the pivot rod. With the rod out of the way, you should be able to lift the stopper right out of the drain opening. If it’s stuck, try jiggling it a bit or giving it a gentle tug.

Removing the Drain Flange

Next up, let’s tackle that drain flange. That’s the circular piece that sits in the sinkhole and connects to the drain assembly below. Reach into the sink and give the flange a counterclockwise twist to loosen it. 

If it’s being stubborn, you may need to use a basin wrench or a pair of pliers for extra leverage. Once it’s loose, lift the flange out of the sinkhole. If there’s any old plumber’s putty or gunk stuck to it, scrape it off with a putty knife or an old toothbrush.

Cleaning the Sink Opening

Before you install the new drain, take a moment to clean out the sink opening. Use a rag or sponge to wipe away any remnants of the old putty or pipe joint compound. Make sure the surface is clean and dry so the new drain can form a tight seal. A little elbow grease now will save you from leaks and headaches later.

Install the New Pop-up Drain Assembly

Out with the old, in with the new. It’s time to install that shiny new pop-up drain assembly. But before you start piecing everything together, let’s make sure you’ve got all the parts laid out and ready to go.

Applying Plumber’s Putty

Remember that tub of plumber’s putty we gathered earlier? Now’s the time to break it out. Grab a generous glob of putty and roll it between your hands to form a long, thin rope. Wrap this putty rope around the underside of the new drain flange, creating a complete circle. This putty will help create a watertight seal between the flange and the sink surface. No leaks on our watch.

Inserting the Drain Body

With your putty in place, it’s time to insert the drain body into the sink opening. Feed the threaded end of the drain body through the drain hole, ensuring the rubber gasket sits flush against the sink bottom. 

From under the sink, slide the friction washer and mounting nut onto the drain body threads. Hand-tighten the nut as far as you can, then give it an extra quarter turn with your trusty channel-type pliers.

Connecting the Pop-up Stopper

Remember that pivot rod we removed earlier? Time to put it back into action. Insert the pivot rod into the opening at the back of the drain body, then slide the pop-up stopper down into the drain opening. 

You may need to wiggle the stopper a bit to get the holes aligned. Secure the pivot rod nut once everything is lined up to hold it all in place. Give the stopper a few test presses to make sure it’s opening and closing smoothly. If it sticks or feels too loose, you may need to adjust the nut slightly.

Attaching the Drain Tailpiece

We’re in the home stretch now. Grab the new drain tailpiece and attach it to the bottom of the drain body. If your tailpiece has threads, simply screw it on clockwise until it’s snug. If it uses a slip joint, slide the slip nut and washer onto the tailpiece, then push the tailpiece onto the drain body until it clicks into place. Tighten the slip nut by hand, then give it an extra quarter turn with your pliers. But be careful not to overtighten – you don’t want to crack the plastic.

Securing the Drain Assembly

Last but not least, it’s time to reconnect the P-trap. Slide the trap back into place, ensuring the washers are seated properly in the slip nuts. Hand-tighten the nuts, then use your pliers to give them an extra quarter turn. Again, don’t go overboard with the tightening – you want a secure connection but not a cracked pipe. 

Once everything is connected, do a quick visual check to ensure all the parts are aligned and nothing looks out of place. If it all looks good, congratulations – you’ve just installed a brand-new sink drain assembly.

Test the New Sink Drain for Leaks

You’ve put in the work; now it’s time to test your new bathroom sink drain. Cross your fingers, turn on the water, and see how she holds up.

Checking for Proper Drainage

First, let’s ensure that water is flowing down the drain like it should. Turn on the faucet and let it run for a minute or two. Keep an eye on the water level in the sink – if it rises or pools around the drain, you may have a clog or leak somewhere in the system. 

Assuming the water is draining properly, it’s time to fill up the sink and really put your new drain through its paces. Plug the sink and fill it with a few inches of water. 

Once it’s full, pull the plug and watch the water whoosh down the drain. You’re in business if it drains quickly and smoothly without any leaks or gurgling noises.

Addressing Any Issues

But what if you do spot a leak or notice some drainage issues? Don’t panic – most problems have a relatively simple fix. If you see water dripping from any connections, try tightening the nuts more with your pliers. If that doesn’t do the trick, you may need to disassemble the leaky section and add more plumber’s tape or pipe joint compound to the threads. Start plunging the sink a few times to see if you can dislodge any blockages for slow drainage or clogs. 

If that doesn’t work, you may need to snake the drain or even remove the P-trap and clean it out manually. And if all else fails, don’t be afraid to call a professional plumber. Better to admit defeat than to make the problem worse by guessing. 

But assuming everything checks out, give yourself a pat on the back – you just successfully replaced your bathroom sink drain like a pro. No more leaks, no more clogs, and a shiny new drain to boot. Now, that’s what I call a DIY victory.
