Here are the steps to deal with the leakage of the toilet water valve:
1. Close the water valve: The first thing to do is to close the main valve of the water inlet pipeline. This will prevent the water valve from leaking continuously, thus minimizing waste.
2. Tighten the water valve: Tightening the water valve is the first step to solve the water leakage problem. If you know where this part is, please open the water valve cover and find the loose part. Tighten the water valve gently with a wrench.
3. Check the seal: If the water valve is still leaking and you think it is tight, then the problem may be due to the damage of the seal. Check the final seal of the water valve for wear, aging or damage. If replacement is needed, please buy a new seal to replace the old parts.
4. Replace the water valve: If the water valve has been seriously worn or damaged, it may be necessary to replace the whole component. Use a suitable tool to remove the water valve or replace it with a new one.
In short, you can take any of the above steps to deal with the leakage of the toilet water valve. If you are not sure whether you can solve the problem, please ask a professional for help.
