Steps to Install the New Overflow Tube

1. Turn off the water supply to the toilet. This is usually located under the sink or behind the toilet. You will need to turn the valve clockwise until it is completely closed.
2. Remove the old overflow tube. The overflow tube is located at the back of the toilet, near the bottom. It is a small, plastic tube that connects to the toilet bowl. To remove it, you will need to unscrew the nut that holds it in place.
3. Clean the overflow hole. Use a rag or paper towel to clean the inside of the overflow hole. This will help to ensure that the new overflow tube fits properly.
4. Apply plumber’s putty to the end of the new overflow tube. This will help to create a watertight seal.
5. Insert the new overflow tube into the overflow hole. Make sure that the tube is inserted all the way in.
6. Screw the nut onto the overflow tube to secure it in place. Tighten the nut until it is snug, but do not overtighten it.
7. Turn on the water supply to the toilet. The water should flow freely into the overflow tube and drain out of the toilet bowl.

Testing the Overflow Tube

Once you have installed the new overflow tube, you should test it to make sure that it is working properly. Here are a few things to check:

  • Make sure that the water is flowing freely into the overflow tube and draining out of the toilet bowl.
  • Listen for any leaks around the overflow tube.
  • Look for any cracks or damage to the overflow tube.
