Common Causes of Water Leakage in New Toilet Tanks：

Here are some things to pay attention to when buying a toilet：
1、When selecting a toilet, choose one from reputable brands. This ensures better quality and durability, reducing the chances of damage and facilitating better solutions in case of issues later on. Additionally, the price of the toilet should be within your personal budget.
2、During the purchase process, inquire about the total price of the toilet and its accessories. Some merchants may charge extra for accessories, leading to increased installation costs and unnecessary hassle.
3、When choosing a toilet, insert your hand into the toilet bowl and check if the drain opening is smooth. This can help determine whether the bowl has undergone glazing, indicating meticulous craftsmanship suitable for daily use.
4、Special attention should be given to the flushing mechanism of the toilet. It is preferable to choose a quiet flushing mode to avoid disturbing the household. A siphonic flushing system can create a vortex, enhancing flushing speed without noise.
5、When installing the toilet, avoid using cement for installation. If thermal expansion and contraction occur, it may cause the toilet to crack, affecting its use.
In summary：we have covered reasons for leaks in new toilet tanks and key considerations when purchasing a toilet. Hopefully, this information is helpful. Paying attention to these details can ensure you buy a quality toilet that guarantees proper usage.
