3. Step-by-Step Guide to Replacing the Overflow Tube

Now that you have your tools, let’s dive into the steps required to replace the sink overflow tube:

Step 1: Turn Off the Water Supply

Before you begin any plumbing work, make sure the water supply is turned off to avoid any accidents. Locate the water shutoff valves under the sink and turn them clockwise until they’re fully closed.

Step 2: Remove the Drain Trap

Place a bucket or towels under the drain trap to catch any remaining water. Use your adjustable wrench to loosen the slip nuts on the drain trap. Carefully remove the trap, and allow any water to drain out.

Step 3: Disconnect the Overflow Tube

Using a wrench or pliers, disconnect the overflow tube from the sink. If the tube is damaged, it might break as you remove it, so be prepared for that. Be sure to clean the area around the connection with a pipe cleaner to remove any debris or buildup.

Step 4: Install the New Overflow Tube

Take your new overflow tube and apply plumber’s tape to the threaded end to create a tight seal. Attach the tube to the sink and tighten it securely. Make sure it’s aligned properly and that the tube fits snugly into place.

Step 5: Reconnect the Drain Trap

Once the overflow tube is installed, reconnect the drain trap. Tighten the slip nuts with the wrench, ensuring everything is secure. Check for any leaks around the connections.

Step 6: Test the Sink

Turn the water supply back on and let the sink fill with water to check for leaks. Ensure that the overflow tube functions properly by allowing the water to drain without any issues. If everything works correctly, you’ve successfully replaced your sink overflow tube!

4. Common Issues and How to Avoid Them

During the replacement process, you may encounter some common issues. Here’s a quick list of potential problems and how to avoid them:

Leaky Connections

If you notice water leaking around the connections, check to ensure that plumber’s tape has been applied properly and that the connections are tightly secured. A small leak can often be fixed by tightening the nuts or adding extra tape.

Incorrect Tube Size

Choosing the wrong size overflow tube is another common issue. Always double-check the dimensions before purchasing a replacement tube. If you're unsure, our team at Plumbers Supply Hub can assist you in selecting the correct size for your sink.
