Over time, bathtub drains can become corroded, clogged, and just plain unsightly. But fear not! In this comprehensive guide, I’m going to walk you through the process of replacing a corroded bathtub drain, step by step.
Why Replace a Corroded Bathtub Drain?
Before we dive into the nitty-gritty of replacing your bathtub drain, you might be wondering why you should bother in the first place. Well, the answer is simple: a corroded drain not only looks bad but can also lead to more significant plumbing issues down the line. Here are a few reasons why you should consider replacing it:
- Improved Aesthetics: Let’s face it, a corroded drain is an eyesore. Replacing it can instantly improve the overall look of your bathroom.
- Prevent Leaks: Corrosion can create cracks and holes in the drain, leading to leaks. Replacing it will help prevent water damage to your home.
- Better Drainage: Over time, corrosion can cause blockages, leading to slow drainage. A new drain will ensure your bathtub drains efficiently.
- Hygiene: Old, corroded drains can be breeding grounds for bacteria and mold. Replacing it will enhance the cleanliness of your bathroom.
Now that we’ve established why you should replace that corroded drain, let’s get to the fun part – the DIY process!
Tools and Materials You’ll Need
Before we start, let’s gather the tools and materials you’ll need for this project. Here’s a checklist:
Tools:
- Adjustable pliers
- Pipe wrench
- Screwdriver (Phillips and flathead)
- Hacksaw
- Plumber’s putty
- Plumber’s tape (Teflon tape)
- Bucket
- Safety glasses
- Gloves
Materials:
- New bathtub drain assembly kit
- Replacement rubber gasket (if not included in the kit)
- Silicone caulk
- Clean rag
Now that you’ve got everything you need, let’s dive into the step-by-step process of replacing that corroded bathtub drain.
Step 1: Prepare Your Work Area
Before you begin, ensure your bathroom is clean and clutter-free. You don’t want to be fumbling around with tools while trying to maneuver in a tight space. Lay down some old towels or rags to protect the tub’s surface from any accidental scratches or damage.
Step 2: Remove the Drain Stopper
Most bathtub drains have a stopper that needs to be removed before you can access the drain itself. This step can vary depending on the type of stopper you have:
- Screw-in stopper: If you have a screw-in stopper, simply unscrew it counterclockwise using your screwdriver.
- Toe-tap stopper: For a toe-tap stopper, you’ll need to remove the overflow plate first. It’s typically held in place by two screws. Once the plate is off, you can access the linkage that connects to the stopper. Disconnect it, and the stopper should come out easily.
Step 3: Remove the Old Drain
Now that the stopper is out of the way, it’s time to remove the old drain:
- Put on your safety glasses and gloves for protection.
- Locate the drain flange, which is the visible part of the drain in the bathtub. It might have a cross or grid pattern, which you can grip with your pliers.
- Use the pliers to grip the drain flange firmly and turn it counterclockwise to unscrew it. If it’s stuck due to corrosion, you may need to use a pipe wrench for extra leverage. Be careful not to damage the tub in the process.
- As you unscrew the drain flange, you’ll expose the drain shoe, a pipe that extends down into the plumbing. Continue unscrewing until the entire drain assembly comes out.
Step 4: Inspect the Drain Shoe and Pipe
With the old drain out of the way, take a moment to inspect the drain shoe and the pipe it’s attached to. Look for any signs of corrosion or damage. If these components are in poor condition, it’s a good idea to replace them as well.
Step 5: Clean the Drain Area
Now that you have removed the old drain, you’ll likely find a layer of old plumber’s putty or silicone caulk around the drain hole. Use your putty knife or a scraper to remove any remnants of the old sealant. Make sure the area is clean and free from debris.
Step 6: Apply Plumber’s Tape
Before installing the new drain, it’s a good idea to wrap the threads of the drain shoe with the plumber’s tape (Teflon tape). This will help create a watertight seal when you install the new drain.
Simply wrap the tape around the threads in a clockwise direction, ensuring that it’s snug but not too thick. Two or three wraps should be sufficient.
Step 7: Install the New Drain
Now it’s time to install the shiny new drain! Here’s how to do it:
- Take your new bathtub drain assembly kit and ensure it includes a rubber gasket. If not, you might need to purchase one separately.
- Apply a thin bead of silicone caulk around the underside of the new drain flange. This will help create a watertight seal when you screw it into place.
- Insert the new drain flange into the drain hole in your bathtub. Make sure it’s centered and press it down firmly.
- Screw the drain flange into the drain shoe. Use your pliers or pipe wrenches for extra leverage if needed, but be careful not to overtighten and damage the tub or the drain assembly.
- Wipe away any excess caulk that squeezes out from under the drain flange.
Step 8: Secure the Rubber Gasket
If your new drain assembly kit includes a rubber gasket, it’s time to secure it in place:
- Place the rubber gasket over the drain shoe, ensuring it covers the flange.
- Press it down firmly to create a tight seal.
Step 9: Reattach the Drain Stopper
Now that the new drain is in place, it’s time to reattach the drain stopper. Follow these steps based on the type of stopper you have:
- Screw-in stopper: Simply screw it back into the drain in a clockwise direction.
- Toe-tap stopper: Reconnect the linkage to the stopper, then reattach the overflow plate using the screws you removed earlier.
Step 10: Test Your New Drain
Before you celebrate your DIY victory, it’s crucial to test your new drain for leaks and proper drainage. Here’s how:
- Fill your bathtub with a few inches of water.
- Let it sit for a few minutes and check for any signs of leakage around the drain area.
- If there are no leaks, pull the stopper and ensure the water drains smoothly.
Step 11: Clean Up and Enjoy
Congratulations! You’ve successfully replaced your corroded bathtub drain. Now it’s time to clean up your work area, dispose of the old drain components responsibly, and enjoy your newly rejuvenated bathtub.
