Need to fix a dripping faucet in your Vancouver home? I know the feeling. Fixing a bathroom sink may not seem thrilling, but with the right guidance and a bit of effort, installing a new faucet can be a breeze. Honestly, I’ve tackled this job more times than I’d like to count!

In this guide, I’ll walk you through the process of installing a bathroom sink drain, including how to install a bathroom sink drain, from gathering your tools to testing for leaks. By the end, you’ll be ready to bid farewell to those pesky drips and enjoy a sink that drains like a dream.

Gather the Necessary Tools and Materials

Before you start installing your new bathroom sink drain, make sure you have all the necessary tools and materials on hand. Trust me; there’s nothing worse than getting halfway through a project only to realize you’re missing a crucial component. I’ve been there, done that – and it’s not fun.

List of Required Tools

Here’s what you’ll need in terms of tools:

• Slip joint pliers
• Laser level (optional but helpful)

Having the right tools will make the job so much easier and help ensure a successful installation.

List of Required Materials

Now, let’s talk materials. You’ll want to gather:

• Plumber’s putty
• Pipe joint compound
• New pop-up drain assembly
• Clean damp rags

I always recommend using high-quality materials. Skimping here can lead to leaks and headaches down the road.

Preparing the Work Area

Before diving in, take a few minutes to prep your work area. Lay down some towels or a drop cloth to protect your bathroom floor. Shut off the water supply to the sink. There’s usually a shut-off valve under the sink or in a nearby cabinet. Place a bucket under the P-trap (that U-shaped pipe) to catch any residual water when you remove it.

Remove the Old Drain Assembly

Alright, let’s get this party started by removing that old, grimy drain assembly.

Disconnecting the Drain Pipe

First up, removing the P-trap. Grab your trusty slip joint pliers and loosen the slip nuts on either end of the P-trap. Have that bucket handy to catch the water that’ll come spilling out. Disconnect the P-trap and move it out of the way.

Removing the Drain Flange

Next, we need to remove the old drain flange from the sink drain opening. This can be a bit tricky, especially if it’s old and corroded. Use your slip joint pliers to loosen the mounting nut securing the drain flange to the sink. You may need to apply some elbow grease here. Once loosened, push up on the drain flange from below while twisting it to break the seal. Lift out the old drain assembly. Victory.

Cleaning the Sink Opening

Before installing the new drain, take a minute to clean the sink opening. Scrape away any old plumber’s putty or gunk with a putty knife. I like to finish up by wiping the area with a damp rag to ensure a clean, smooth surface for the new drain. Trust me, a little prep work goes a long way.

Install the New Pop-up Drain Assembly

Now for the main event: installing your shiny new pop-up drain assembly.

Applying Plumber’s Putty

Start by applying a generous bead of plumber’s putty around the drain opening on the underside of the sink. This will create a watertight seal. Roll the putty between your hands to warm it up and make it more pliable. Then, simply press it into place around the opening.

Inserting the Drain Body

Next, insert the drain body through the drain opening from below the sink. Make sure the rubber gasket is in place on top of the sink surface. From above, thread the flange onto the drain body and hand-tighten. The flange should compress the putty, creating a nice, tight seal.

Securing the Drain Body

Grab your slip joint pliers and give the flange a quarter turn to fully tighten it. Don’t overdo it, or you risk damaging the sink or flange. Wipe away any excess putty that may have squeezed out with a damp rag.

Connecting the Pivot Rod

Locate the hole for the pivot rod on the back of the drain body. Insert the pivot rod through this hole. The pivot rod connects to the lift rod of your faucet, allowing you to open and close the pop-up stopper. Adjust it as needed to ensure smooth operation.

Connect the Drain Pipe to the Pop-up Assembly

You’re in the home stretch now. It’s time to reconnect all the drain pipes.

Attaching the Tailpiece to the Drain Body

Take the tailpiece (the straight section of pipe) and attach it to the drain body. There’s usually a washer and slip nut that secures this connection. Slide the slip nut onto the tailpiece, followed by the washer. Then, insert the tailpiece into the drain body and hand-tighten the slip nut.

Installing the Trap Adapter

The trap adapter is a short, curved section of pipe that connects the tailpiece to the P-trap. It often has slip nuts on both ends. Attach one end of the trap adapter to the tailpiece, securing it with the slip nut and washer. Hand-tighten for now.

Connecting the Drain Pipe

Now, it’s time to reconnect the P-trap. Attach the other end of the trap adapter to one side of the P-trap, again using the slip nuts and washers. Then, connect the other side of the P-trap to the drain pipe coming out of the wall. Make sure all connections are snug and properly aligned. Once everything is in place, go back and give each slip nut a quarter turn with your slip joint pliers to fully tighten.

Test for Leaks and Make Final Adjustments

You’re almost done. Just a few final steps to ensure your new drain is functioning properly.

Filling the Sink with Water

Turn the water supply back on and let the sink fill up. This is the moment of truth where you’ll find out if you have any leaks. As the sink is filling, closely inspect all the drain connections underneath. Look for any signs of water dripping or seeping out.

Checking for Leaks

If you spot a leak at any of the connections, don’t panic. Most likely, the slip nut just needs a bit more tightening. Use your slip joint pliers to give the leaking connection a quarter turn. Then, check again to see if the leak has stopped.

Adjusting the Pop-up Mechanism

Test out your new pop-up drain stopper. Push down on the lift rod to make sure the stopper goes down and seals properly. If the stopper isn’t sealing or seems misaligned, you may need to adjust the pivot rod. Loosen the nut on the pivot rod, reposition as needed, and re-tighten.

Tightening the Connections

Once you’ve confirmed there are no leaks and the pop-up mechanism is working smoothly, go back and give all the slip nuts a final quarter turn with your slip joint pliers. This ensures a watertight seal at each connection point. Just be careful not to over-tighten and damage the washers or nuts. 

And there you have it. You’ve successfully installed your new bathroom sink drain. Stand back and admire your handiwork. 

As you can see, with the right tools, materials, and a little know-how, installing a bathroom sink drain is a very doable DIY project. I hope this guide has given you the confidence to tackle this task in your own home.
