Your bathtub drain works hard every day, handling everything from soap to hair and dirt, which can lead to wear and tear over time. Over the years, you might notice that your bathtub isn’t draining as efficiently, or you may experience persistent leaks or rusting. These are signs that it’s time to remove and replace bathtub drain. While replacing a bathtub drain may seem like a job for a plumber, it’s actually a task that most DIY enthusiasts can handle with a few simple tools and a bit of patience.
In this guide, we’ll take you through the entire process of removing and replacing a bathtub drain. From understanding when it’s time for a replacement to gathering the right tools and following step-by-step instructions, we’ve got you covered. Replacing an old or damaged bathtub drain can improve your tub’s efficiency, prevent leaks, and save you from costly repairs down the road.
Let’s get started with an overview of when and why you should replace your bathtub drain.
When Should You Remove and Replace Bathtub Drain?
Knowing when it’s time to remove and replace your bathtub drain is crucial to maintaining the health of your plumbing system. Over time, your drain may show signs of wear that can lead to more significant issues if left unchecked. Here are some key indicators that your bathtub drain needs replacement:
- Leaking water: One of the most common signs that your bathtub drain needs replacing is persistent leakage. Water pooling around the base of the tub or dripping below is often due to a worn-out or improperly sealed drain.
- Slow drainage: If water takes a long time to drain after a bath, even after regular cleaning, your drain may be partially blocked by debris, corrosion, or buildup that can’t be easily removed.
- Rusted or damaged components: Rust or corrosion around the drain indicates that the metal components are deteriorating. This can weaken the drain’s structure and lead to further damage if not addressed.
- Frequent clogs: While clogs can often be fixed with a drain snake or cleaner, frequent blockages may signal that the drain is damaged or improperly aligned.
- Cosmetic reasons: In some cases, you might want to replace an old or discolored drain to give your bathtub a fresher look, especially during bathroom renovations.
Benefits of replacing an old or damaged drain include improved water flow, prevention of leaks that can cause costly water damage, and a cleaner, more modern appearance.
Tools and Materials You’ll Need for the Job
Before diving into the removal and replacement process, it’s important to gather the necessary tools and materials. Having everything on hand will make the job go more smoothly and help prevent any mid-project frustrations.
Here’s what you’ll need:
- Bathtub drain removal tool (drain wrench or drain extractor): This tool is essential for unscrewing and removing the old drain without damaging the surrounding area.
- Plumber’s putty: Used to create a watertight seal around the new drain.
- Adjustable wrench: Useful for loosening and tightening components.
- Screwdriver: To remove any screws holding the drain cover or stopper in place.
- Drain replacement kit: Includes the new drain, flange, and possibly a new stopper, ensuring a proper fit.
- Teflon tape: Helps create a tight, leak-proof seal on threaded connections.
- Bucket and rags: For cleaning up any water that remains in the pipes or tub during the process.
Optional materials:
- Silicone sealant: Some people prefer silicone sealant instead of plumber’s putty for certain types of drains.
- Drain snake: In case you need to clear out any debris from the drainpipe before installing the new drain.
With these tools and materials on hand, you’ll be ready to efficiently remove and replace your bathtub drain without needing to run to the hardware store in the middle of the project.
How to Remove a Bathtub Drain: Step-by-Step Instructions
Removing the old bathtub drain is the first step in this process, and it’s crucial to do it carefully to avoid damaging the surrounding tub or pipes. Follow these instructions to remove the drain safely and efficiently.
Step 1: Turn off the water supply and clear the area
Before you start, it’s a good idea to turn off the water supply to your bathroom, especially if you’re dealing with a leak. This prevents any accidental water spills while you work. Lay down rags or towels around the tub to catch any residual water, and make sure the bathtub is completely dry.
Step 2: Remove the drain stopper or cover
If your bathtub has a drain stopper or cover, use a screwdriver to remove any screws holding it in place. Once the screws are removed, you should be able to lift the stopper or cover off easily. Set these parts aside, as you may need to reinstall them later.
Step 3: Use the drain wrench to unscrew the old drain
Insert the bathtub drain wrench into the drain and turn it counterclockwise to loosen the drain flange. The wrench will grip the inner crossbars of the drain, allowing you to unscrew it without damaging the tub. If the drain is rusted or stuck, you may need to apply extra pressure or use a lubricant like WD-40 to loosen it.
Step 4: Clean the area and inspect for damage
Once the old drain is removed, clean the surrounding area with a rag to remove any old plumber’s putty, debris, or rust. Inspect the drain opening and pipe for any signs of damage, such as cracks or corrosion. If everything looks good, you’re ready to move on to the next step: installing the new drain.
How to Install a New Bathtub Drain
Now that the old drain has been removed, it’s time to install the new one. This step requires precision to ensure a tight seal and prevent future leaks.
Step 1: Apply plumber’s putty to the new drain flange
Take a small amount of plumber’s putty and roll it into a thin rope. Apply it around the bottom edge of the new drain flange. This will create a waterproof seal when the drain is tightened down.
Step 2: Secure the new drain using a drain wrench
Insert the new drain into the opening and begin threading it into place by hand. Once it’s snug, use the drain wrench to tighten it further, turning clockwise until the drain is firmly secured. Be careful not to overtighten, as this could crack the tub or damage the threads.
Step 3: Install the drain cover or stopper
Reattach the drain cover or stopper using a screwdriver to secure it in place. If you’re using a new drain kit, follow the instructions provided for installing the stopper mechanism.
Step 4: Connect the drain to the waste pipe and test for leaks
Reconnect the drainpipe to the waste pipe using Teflon tape to ensure a tight seal. Once everything is connected, turn the water supply back on and test the drain by filling the bathtub with water. Watch for any signs of leaks around the new drain.
Tips for a Leak-Free Installation
Ensuring a leak-free installation is the goal when replacing a bathtub drain. Here are some extra tips to help you get the best results:
- Properly apply plumber’s putty: When applying plumber’s putty around the drain flange, make sure it’s evenly distributed to create a tight, waterproof seal.
- Use Teflon tape: Wrapping Teflon tape around the threads of the drain helps create a watertight connection and prevents leaks.
- Check for leaks: After installing the new drain, test it by filling the bathtub and checking for leaks around the flange and drainpipe. If you notice any drips, tighten the connections or add more putty or sealant.
- Avoid overtightening: While it’s important to make sure the drain is secure, overtightening can cause cracks in the tub or damage the threads, leading to leaks in the future.
By following these tips, you’ll ensure that your new bathtub drain remains leak-free and functional for years to come.
