In real life, when using a toto toilet, if the toilet tank keeps running, here are some solutions to fix it.

How to Fix a Toto Toilet Tank That Keeps Running

If the toto toilet tank is continuously running, it may be due to the plastic flush valve inside the tank being misaligned. In this case, repeatedly pressing the flush button can help the valve quickly reset, which should resolve the running water issue. It could also be that the water level device is set too high and has become loose during use. To fix this, you need to open the tank and adjust the water level device to the appropriate position.

What to Consider When Choosing a Toilet

1、When selecting a toilet, check the quality of the ceramic. Generally, high-quality toilets have a very fine ceramic texture and a highly polished glaze surface, making it difficult for dirt to seep into the porcelain. Therefore, they are easier to clean. Also, make sure to measure the wall distance in your bathroom before choosing a toilet with the right dimensions.

2、Toilets typically have either front or rear drainage outlets. Front drainage toilets are suitable for bathrooms with a larger wall distance, while rear drainage toilets are better for bathrooms with a shorter wall distance.

3、Additionally, check the toilet's anti-backflow feature. This is usually related to the height of the water seal, which should not be less than 50mm. If the height is below this, you may experience backflow issues.

4、When buying a toilet, also consider the flushing method. The most common type on the market is the siphonic flushing method, which utilizes a vacuum in the pipes to quickly flush the entire toilet. This method is particularly convenient, clean, and operates quietly.

In summary:the above content outlines how to fix a toto toilet tank that keeps running. I hope it helps everyone.
