How to Fix a Toilet That Leaks Water When Flushed

Toilet leaks are a common issue that can affect daily use. So, how to solve the problem of a toilet leaking at the back every time it is flushed? Let's take a look.

How to solve the problem of a toilet leaking at the back every time it is flushed：

1、First, identify the cause of the leak. If the flange inside the toilet has a problem, it needs to be replaced immediately.

2、If there are cracks in the seal between the toilet and the floor causing the leak, you can apply silicone sealant to the gap, and once it dries, the issue should be resolved.

3、If internal components of the toilet are damaged, they should be replaced with new parts right away.

What causes a toilet to leak at the back：

1、Poor sealing of the flush valve connection

The toilet is equipped with a flush valve, and if its sealing is not effective, pressure from the water can cause leaks through the gaps. Therefore, when there is a leak, check if the flush valve has any issues.

2、Flush button not resetting

Some toilets have a flushing button that can wear out over time, preventing it from resetting, which can lead to leaks. If the issue is with a worn-out button, you can replace it with a new one to ensure proper functioning.

3、Loose float ball and water tank inlet

It could also be that the float ball and water tank inlet are loose, causing the toilet to leak continuously. In this case, tighten the float ball to prevent further leakage.

4、Clogged rubber seal at the water tank outlet

When the toilet leaks, it might also be due to the outlet rubber seal being blocked by foreign objects, which can cause the toilet to run continuously. If this is the case, you need to remove the obstruction from the outlet rubber seal to resolve the leak.

In summary：The above is related to how to solve the issue of a toilet leaking at the back every time it is flushed. Hopefully, everyone understands! There are many reasons for toilet leaks, usually related to internal components, so it’s best to replace any aging parts
