Trust us, meticulous preparation saves time, money, and a whole lot of… now we’re ready to tackle the removal process! Removing the old drain requires patience, the right technique, and a willingness to adapt to unexpected challenges. This step-by-step guide will walk you through the process.

Initial Inspection: Assessing the Situation

Begin by carefully examining the existing drain.

Look for any visible damage, such as cracks, rust, or excessive corrosion. These signs can indicate the drain’s overall condition and potential points of weakness.

Next, identify the type of drain and stopper mechanism. Common types include pop-up, lift-and-turn, and toe-touch drains. Understanding the mechanism is crucial for choosing the appropriate removal method.

Loosening the Drain: The Power of Penetration

Penetrating oil is your best friend when dealing with corroded plumbing.

Apply a generous amount of penetrating oil (like WD-40 or Liquid Wrench) to the drain threads, both from inside the tub and underneath, if accessible.

Allow the oil to soak for at least 15-30 minutes, or even longer for heavily corroded drains. This will help loosen the rust and grime, making the drain much easier to remove. Patience is key here!

Employing the Right Tools: Wrenching it Loose

With the penetrating oil working its magic, it’s time to bring in the muscle.

Using the Bathtub Drain Wrench

The bathtub drain wrench (also sometimes called a dumbbell wrench or tub drain tool) is specifically designed for this task.

Insert the wrench into the drain opening, ensuring the teeth engage securely with the drain flange.

Turn the wrench counterclockwise to loosen the drain. Apply steady, even pressure. Avoid forcing it, as this could damage the drain or the tub.

Alternative Methods

Sometimes, the drain isn’t budging with the drain wrench. Or, perhaps you encounter a different drain design altogether.

Drains secured with screws: Some older drains may be secured with screws around the flange. Use the appropriate screwdriver (flathead or Phillips) to remove these screws before attempting to unscrew the drain body.

Stubborn Drains: For drains that are particularly stubborn, carefully use pliers or an adjustable wrench to grip the drain body from underneath. Apply gentle, controlled pressure while turning counterclockwise. Be extremely cautious not to damage the surrounding plumbing or the tub itself.

Handling Difficult Drains: When Things Get Tricky

Not all drain removals are created equal. Sometimes, things get complicated.

Stripped Threads: If the threads are stripped, proceed with extra caution. Apply more penetrating oil and try using gentle pressure. You may need to try different angles or tools to get a grip.

When to Call a Plumber: This is crucial: If the drain is severely stuck, damaged, or you’re uncomfortable proceeding, STOP and call a professional plumber. Forcing the issue can lead to bigger problems, such as damaging the tub or breaking pipes. It’s better to be safe than sorry.

Disconnecting the Stopper: Freeing the Flow

The final step in removing the old drain is disconnecting the stopper mechanism.

Locate the stopper linkage under the sink. This typically involves a series of rods and levers connected to the drain stopper.

Carefully disconnect the linkage, usually by loosening screws or detaching clips.

Once the linkage is disconnected, carefully remove the old drain stopper from the top of the drain. You should now have a completely free drain, ready for removal.

Preparing for the New: Cleaning and Inspection

With the old drain finally out of the way, it’s tempting to rush into installing the new one. Resist this urge! Taking the time to properly prepare the area is crucial for ensuring a long-lasting, leak-free installation. This involves more than just a quick wipe-down; it’s about setting the stage for success.

Cleaning the Drain Opening: A Fresh Start

Think of the drain opening as a canvas.

Before you can create a masterpiece (a perfectly sealed drain), you need to ensure it’s clean and ready to receive the new fixture.

This means meticulously removing any remnants of the old installation.

Scrape away the old, hardened plumber’s putty.

Any bits of sealant or debris must be eliminated. A putty knife or a stiff brush can be helpful here.

Consider using a solvent like mineral spirits to dissolve stubborn residue.

The goal is to achieve a perfectly clean, dry, and smooth surface. This allows the new plumber’s putty to form a proper bond.

Don’t underestimate this step! A little extra effort here can prevent leaks down the road.

Inspecting the P-Trap: Below the Surface

While you’re under the sink, take a good look at the P-trap. This curved section of pipe plays a crucial role in preventing sewer gases from entering your home.

Over time, P-traps can accumulate debris and sediment, leading to clogs and slow drainage.

Thoroughly inspect the P-trap for any signs of damage.

Look for cracks, leaks, or corrosion.

If you notice any issues, it’s best to replace the P-trap while you’re already working on the drain.

This is an inexpensive repair.
It ensures proper drainage and prevents potential plumbing problems.

Even if the P-trap appears to be in good condition, consider removing it to check for any hidden clogs.

You can flush it out with water or use a plumbing snake to clear any obstructions.

A clean and functional P-trap is essential for maintaining a healthy plumbing system and preventing unpleasant odors.

Installing the New Drain: Putting it All Together

Before diving headfirst into replacing that bathtub drain, pausing to gather the right tools and materials is paramount. It’s the difference between a smooth, satisfying DIY experience and a frustrating, water-logged mess. Trust us, meticulous preparation saves time, money, and a whole lot of clean-up.

Now that you’ve successfully removed the old drain and prepared the area, it’s time for the rewarding part: installing the new one. This section will guide you through each step, ensuring a watertight and secure fit. Let’s get started.

Applying Plumber’s Putty: Creating the Initial Seal

This is where we create the foundation for a leak-proof installation. Plumber’s putty acts as a pliable barrier, conforming to any slight imperfections between the drain flange and the tub’s surface.

1. Start by taking a generous amount of plumber’s putty and rolling it between your hands to create a rope approximately ¼ to ⅜ inch thick.

2. Apply this rope to the underside of the new drain flange, ensuring complete coverage around the entire circumference.

   The goal is to create a continuous, unbroken seal. Press the putty firmly against the flange to ensure good adhesion.

Inserting the New Drain: Align and Gently Insert

With the plumber’s putty in place, carefully position the new drain assembly.

1. From underneath the tub, carefully insert the new drain body up through the drain opening.

2. Simultaneously, align the new drain flange on top of the drain opening inside the bathtub.

   Ensure the flange sits flush against the tub’s surface. The putty should slightly squeeze out as you press the flange into place. This is a good sign, indicating a proper seal.

Tightening the Drain: Snug, Not Strained – A Delicate Balance

This step requires a gentle touch. Overtightening can damage the tub or the drain itself.

1. Using your bathtub drain wrench from above, carefully tighten the new drain.

2. Apply consistent, even pressure, turning the wrench clockwise.

   The key is to achieve a snug fit, not an excessively tight one. As you tighten, the plumber’s putty will continue to compress, filling any remaining gaps. Stop tightening when you feel resistance and the flange is firmly seated against the tub.

Connecting the Stopper Linkage: Reconnecting the Mechanism

Now, let’s get that stopper working again! This step involves reconnecting the linkage that controls the drain stopper.

1. Locate the stopper linkage under the sink. Carefully reattach it to the new drain assembly, following the manufacturer’s instructions.

2. Adjust the linkage as needed to ensure proper stopper operation.

   The stopper should fully open and close without sticking or binding. Test the stopper several times to confirm smooth and reliable operation. A properly adjusted linkage is crucial for preventing leaks and ensuring efficient drainage.

Sealing the Threads: Extra Insurance Against Leaks

While the plumber’s putty creates the primary seal, Teflon tape provides an additional layer of protection, especially for threaded connections.

1. Apply Teflon tape to any threaded connections on the drain assembly, wrapping it clockwise several times.

2. This will help create a watertight seal and prevent leaks over time.

   Remember, Teflon tape is inexpensive insurance against future headaches. It fills microscopic imperfections in the threads, ensuring a tight and leak-free connection.

Testing and Adjustments: Ensuring a Leak-Free Fit

After meticulously installing your new bathtub drain, the moment of truth arrives: testing for leaks. This step is crucial, as even a minor drip can lead to significant water damage over time. A little patience and careful observation here can save you from headaches down the road.

The Water Test: Patience is Paramount

The first step is to slowly turn the water supply back on. Avoid the temptation to crank it open fully right away. Give the system a chance to pressurize gradually.

This controlled approach allows you to spot leaks more easily before they escalate into a gusher.

As the water flows, carefully inspect all connections, paying particular attention to where the drain meets the tub and where the P-trap connects to the drainpipe.

Use a flashlight to get a better view of any tight spaces.

Feel around the joints with a dry hand; even the slightest moisture will indicate a leak. Don’t neglect the area around the new drain flange inside the tub.

Identifying and Addressing Leaks

If you discover a leak, don’t panic. The majority of leaks can be resolved with a few simple adjustments. The key is to identify the precise source of the leak before attempting any repairs.

Is the leak coming from a threaded connection? If so, try gently tightening the fitting with an adjustable wrench. Remember, the goal is snug, not strained.

Overtightening can damage the threads and make the problem worse. A quarter-turn might be all it takes to seal the leak.

If the leak persists, you may need to disconnect the fitting, apply fresh Teflon tape to the threads, and reassemble.

For leaks around the drain flange inside the tub, ensure the plumber’s putty is properly seated and compressed. If necessary, you may need to carefully remove the drain, reapply the putty, and re-tighten the drain.

Stopper Functionality: Completing the Seal

Once you’ve confirmed there are no leaks, it’s time to test the drain stopper. Fill the tub with a few inches of water and observe how well the stopper seals.

Does the water slowly drain away, or does the stopper hold it effectively?

If the stopper isn’t sealing properly, adjust the linkage connecting the stopper to the lever. Most stoppers have an adjustable rod or mechanism that allows you to fine-tune the stopper’s position.

Experiment with small adjustments until you achieve a tight seal.

A properly functioning stopper is essential for enjoying a relaxing bath without wasting water.

By methodically testing and adjusting your new bathtub drain, you can ensure a leak-free and fully functional plumbing system. This final step is just as important as the installation itself, providing peace of mind and protecting your home from potential water damage.
