DIY Bathroom Fix: Master the Art of Changing an Overflow Tube

Overflow tubes play a crucial role in preventing water from overflowing from sinks, bathtubs, and other plumbing fixtures. When these tubes become clogged or damaged, they can lead to messy spills and water damage. Fortunately, changing an overflow tube is a relatively simple task that most DIYers can handle with the right tools and materials.

Tools and Materials You’ll Need

• New overflow tube
• Plumber’s putty
• Adjustable wrench
• Screwdriver
• Utility knife
• Rags or towels

Step-by-Step Instructions

1. Turn Off the Water Supply

Before you begin, turn off the water supply to the fixture with the overflow tube. This will prevent water from leaking out while you’re working.

2. Remove the Overflow Plate

Use a screwdriver to remove the overflow plate, which is typically located near the top of the fixture. The plate may be held in place by screws or clips.

3. Disconnect the Old Overflow Tube

Once the overflow plate is removed, you’ll see the old overflow tube connected to the drain assembly. Use an adjustable wrench to loosen the nuts that hold the tube in place.

4. Remove the Old Tube

Gently pull the old overflow tube out of the drain assembly. If it’s stuck, you can use a utility knife to carefully cut it free.

5. Prepare the New Overflow Tube

Apply a thin layer of plumber’s putty around the end of the new overflow tube. This will help create a watertight seal.

6. Insert the New Tube

Insert the new overflow tube into the drain assembly and hand-tighten the nuts.

7. Tighten the Nuts

Use the adjustable wrench to tighten the nuts that hold the overflow tube in place. Make sure they’re snug but don’t overtighten them.

8. Reinstall the Overflow Plate

Place the overflow plate back in its original position and secure it with screws or clips.

Troubleshooting Tips

• If the overflow tube is still leaking after you’ve replaced it, check the plumber’s putty seal. It may need to be replaced or tightened.
• If the overflow tube is clogged, you can try to unclog it using a drain snake or chemical cleaner.
• If the overflow tube is damaged, it will need to be replaced.
