The toilet is used very frequently in daily life, and after prolonged use, it inevitably experiences some issues, such as the water inlet valve not shutting off. So, what should you do if the toilet water inlet valve does not stop water flow?

Troubleshooting a Toilet Fill Valve That Doesn't Stop Filling:

1、The float ball or float cylinder of the toilet water inlet valve may be stuck, causing the valve to not shut off. In this case, you can manually lift and lower the float ball or float cylinder to allow it to move freely.

2、The water inlet valve may be clogged by foreign objects, which prevents it from shutting off. In this situation, it is advisable to seek help from professionals or directly replace the water inlet valve.

3、If the internal parts of the water inlet valve are damaged, it is difficult to repair, and it is recommended to replace the valve with a new one.

Proper Maintenance Methods for Toilets:

1、When cleaning the toilet, use a dedicated toilet cleaner. Do not use dishwashing liquid, and avoid scrubbing the toilet's glazed surface with steel wool, as it may damage the glaze. Instead, use a soft cloth or a toilet brush for cleaning.

2、Many people throw tissues into the toilet. If these are fiber-based, they can easily cause clogs, especially wet wipes. Do not throw them directly into the toilet after use to avoid blocking the outlet.

3、If the toilet becomes clogged, you can use baking soda or vinegar to flush it. If that does not work, it is best to call a professional. After resolving the issue, try to avoid dropping paper scraps, hair, etc., into the toilet.

4、After prolonged use, the toilet needs to be disinfected, typically every seven days. You can use disinfectant to ensure the toilet remains hygienic.

In conclusion:the above content outlines how to handle a toilet water inlet valve that does not shut off. It is important to identify the cause of the issue and take targeted action to prevent disruptions in the normal use of the toilet.
