Hello there! I'm a seasoned plumber with years of experience in fixing all sorts of household plumbing issues, including the common problem of a toilet that won't stop running. It can be quite frustrating to hear the constant sound of water running, not to mention the water waste it causes. Let's dive into the steps you can take to fix this issue.

Firstly, it's important to understand the basic anatomy of a toilet tank. The water level in the tank is controlled by a fill valve, which is connected to a float. When the toilet is flushed, the water level drops, and the fill valve opens to allow water to refill the tank. The float rises as the water level rises, and when it reaches a certain point, it triggers the fill valve to close, stopping the flow of water.

Now, if your toilet is running continuously, it usually means that the water level in the tank is too high, and the fill valve is not closing properly. Here's how you can address this:


1. Turn Off the Water Supply: Locate the water supply valve behind the toilet and turn it clockwise to shut off the water supply to the toilet.


2. Empty the Tank: Flush the toilet to empty the water from the tank. You can also use a sponge or towel to soak up any remaining water.


3. Inspect the Fill Valve: Remove the top of the toilet tank to access the fill valve. Look for any visible damage or obstructions that might be preventing the valve from closing.


4. Adjust the Fill Valve: The fill valve has a screw at the top that adjusts the height of the float. You'll need to adjust this so that the water level stops filling approximately 1 inch below the top of the overflow tube. This is a critical step, as setting the water level too high can cause the toilet to run continuously.


5. Check the Float: The float is what controls the water level in the tank. If it's damaged or stuck, it may not be able to signal the fill valve to stop the water flow. Ensure the float is functioning properly.


6. Replace Parts if Necessary: If the fill valve or float is damaged, you'll need to replace them. It's best to purchase parts that are compatible with your toilet model.

7.
Test the Toilet: Once you've made the adjustments, turn the water supply back on and allow the tank to refill. Check to see if the toilet stops running.

8.
Monitor Water Usage: After fixing the issue, keep an eye on your water bill to ensure that the problem has been resolved.

Remember, it's crucial to address this issue promptly, as a continuously running toilet can waste a significant amount of water and money over time. If you're not comfortable performing these steps yourself, it's always a good idea to call a professional plumber.

Now, let's move on to the Chinese translation of the steps I've outlined above.
