Identifying the Culprit: Symptoms of a Leaking Overflow Tube

• Adjustable wrench

Step-by-Step Guide to Fixing a Leaking Overflow Tube

1. Turn Off the Water Supply

Locate the water supply valve behind the toilet and turn it clockwise to shut off the water flow.

2. Flush the Toilet

Flush the toilet to empty the bowl and tank. This will give you a clear view of the overflow tube.

3. Disconnect the Water Supply Line

Using an adjustable wrench, carefully loosen the nuts that connect the water supply line to the fill valve.

4. Remove the Overflow Tube

Locate the overflow tube, which is typically attached to the flush valve. Using the wrench, loosen the nut that secures it. Gently pull the tube free.

5. Inspect the Overflow Tube and Gasket

Check the overflow tube for any cracks or damage. If it’s damaged, you’ll need to replace it. Inspect the gasket at the bottom of the tube as well. If it’s worn or damaged, replace it.

6. Wrap the Overflow Tube with Plumber’s Tape

Apply a few wraps of plumber’s tape around the threads of the new or repaired overflow tube. This will help create a watertight seal.

7. Reinstall the Overflow Tube

Insert the overflow tube into the flush valve and tighten the nut securely. Make sure the gasket is properly seated.

8. Reconnect the Water Supply Line

Reattach the water supply line to the fill valve and tighten the nuts. Turn on the water supply and check for leaks.

9. Clean Up

Use toilet bowl cleaner to clean any remaining water or debris from the toilet and surrounding area. Wipe everything dry with rags or towels.

Troubleshooting Tips

• If the leak persists after you’ve replaced the overflow tube, check the fill valve. It may need to be adjusted or replaced.
• If water is dripping from the top of the overflow tube, adjust the water level in the tank. The water level should be about 1 inch below the top of the overflow tube.
• If the overflow tube is clogged, use a small brush or wire to clear the obstruction.

When to Call a Plumber

If you’re unable to fix the leak on your own or if the problem is more complex, don’t hesitate to call a licensed plumber. They have the experience and expertise to diagnose and resolve any toilet issues you may encounter.
