How to Change Overflow Tube in Toilet?

To replace the overflow tube toilet, you must remove the toilet tank lid and disconnect the refill tube from the overflow pipe. I came to know this recently. I noticed my toilet tank started refilling endlessly and was unsure why is it happening. So I immediately called a plumber. He said it happened because of the overflow tube as it had cracked over time. Here is how to change toilet overflow tube.

How to Replace Toilet Overflow Tube?

1. There must be a water shutoff valve in the wall beneath your toilet. To shut the valve, simply rotate the knob clockwise. 

2. After that, empty the tank of water by flushing your toilet. 

3. Take off the lid of your toilet tank. Place it in a secure location that will prevent it from being dropped and shattered. 

4. Empty the tank to the flapper's top by lifting the flapper chain. 

5. Now detach the refill tube from the overflow pipe. 

6. Use a sponge to soak up all of the remaining water in the tank. 

7. Unscrew the flush valve assembly, which holds the overflow tube in position. Remove the old tube. 

8. Insert the new overflow tube into the flush valve aperture. Ensure it is the same height and model. 

9. Use the locknut to firmly tighten the new overflow tube. 

10. Reattach the refill tube and make sure all seals are tight.

11. Restart the water and await the filling of the tank. 

12. Finally, after one flush, look for any leaks or improper water flow.

According to me, this is not a DIY task, as it requires specific tools, knowledge and experience. This is all about how to change overflow tube in toilet.
