Common Causes of Toilet Fill Valve Leakage and How to Fix It

Toilet leaks can involve issues with the water inlet valve, the tank, or the toilet body itself. Let's take a look at the causes and solutions for leaks specifically related to the toilet water inlet valve.

Causes and Solutions for Toilet Water Inlet Valve Leaks：

1、Seal Failure Causing Leaks

The water inlet valve is connected via a sealing ring, which can become aged or deformed over time, leading to leaks. To address this, you should turn off the main water valve at home, then disassemble the inlet valve, remove the sealing ring, clean it thoroughly, and replace it with a new one to resolve the issue.

2、Damage to the Water Inlet Valve Causing Leaks

The inlet valve may be broken from impacts during use or may have quality issues with gaps that can cause leaks. In this case, you can disassemble the inlet valve, purchase a new valve with the same diameter, and install it properly.

Types of Toilet Leaks：

1、Tank Leaks

Tank leaks generally occur for two reasons: a damaged water pipe connection or a fault in the tank itself. Another common issue is continuous water flow from the tank, which means the tank cannot hold water. This can prevent normal flushing, possibly due to loose connections that prevent the float from functioning properly, leading to leaks.

2、Toilet Body Leaks

Toilet bodies are often made from materials with low durability; if the porcelain isn't well-finished, it might develop cracks or damages over time, leading to leaks. Even if repaired, such leaks tend to recur, so replacing the toilet is usually advisable.

3、Water Inlet Valve Leaks

As mentioned earlier, if the water inlet valve is not equipped with a filter, it can easily develop leak issues due to clogging from impurities and particles in the tap water. This can lead to damage to the sealing ring and cause leaks.
