It is a common problem that water keeps flowing after flushing the toilet. Sometimes this situation even lasts for a long time, causing water waste and environmental pollution. Here are some reasons why this might be happening and how to fix it.
Causes:
1. There is a problem with the internal parts of the water tank. For example, if the water level adjustment device is damaged or improperly adjusted, it may cause excessive flushing or the water tank is not fully filled with water, resulting in long-term water flow problems.
2. The water valve or the high-pressure valve inside the water tank is damaged or loose. The high-pressure valve is one of the key parts for controlling water flow. If it is not adjusted to the appropriate position or is damaged, it will cause excessive water flow in the water tank and the water flow will not stop.
3. The water tank is not tightly sealed. If the water tank is not well sealed, air will enter the water tank and flow outward, causing the water tank to be unable to be fully filled with water, leading to long-term water leakage problems.
Solution:
1. Check the water level adjustment device. The water level adjustment device of the lift-type water tank is generally set in the side wall of the water tank. If the water level adjustment device is found to be damaged or improperly adjusted, it can be adjusted to the appropriate position to alleviate the problem of excessive flushing.
2. Check the water valve or high-pressure valve. First open the water tank and check whether the high-pressure valve is tight. If it is loose, adjust it to the appropriate position. If damage occurs, the high-pressure valve will need to be replaced with a new one.
3. Check the seal. First, you need to check whether the water tank is installed correctly and tightened. If the problem still exists, it may be because the sealing gasket is damaged and needs to be replaced with a new one.
In addition, it should be noted that if there is still no improvement after trying the above methods, you can disassemble and check whether other parts inside the water tank are damaged. In addition, if you need to change the flushing volume, you can adjust the water level adjustment device inside the water tank or install a flushing volume pressure reducer.
Finally, we need to be reminded that since there are electrical appliances and wires inside the water tank, if you don’t know how to install and operate it, please find a professional plumber for repairs. At the same time, before internal repairs and installations, it is best to turn off the water source or turn off the relevant switches to ensure your own safety.
