How to Resolve Toilet Tank Water Filling Issues: Tips and Tricks

In daily life, most people have encountered the situation where the toilet tank doesn't fill with water. So, what should one do when the toilet tank isn't filling with water? Let's find out.

What to do when the toilet tank isn't filling with water：

There are typically two main reasons: first, there may be an issue with the toilet itself, and second, a component in the toilet tank may be damaged.

In this situation, the toilet may appear to be functioning normally on the outside, but in reality, water is continuously flowing, which results in the tank not filling up. We can start by turning off the water supply valve, draining the water from the tank, then adding colored dye to the remaining water in the tank and waiting for 30 minutes to see if any color appears elsewhere. If color appears, it indicates that there is a crack inside the toilet, and the only solution is to replace the toilet.

Additionally, another significant cause may be damaged components within the tank. In this case, we need to open the tank and inspect the various components to determine their condition. If any parts are missing, the simplest solution is to replace those parts. However, if the internal components are no longer replaceable, we will have to replace the entire tank. In summary, if the toilet tank isn't filling with water, it could either be due to damage to the tank itself or a crack inside the toilet.

Common reasons for toilet tank leaks：

1、The rubber ball valve is damaged

If the rubber ball valve is damaged, the tank's sealing will deteriorate, causing water to continuously flow out. In this case, replace it with a rubber ball valve of the same model.

2、The rubber gasket at the drain hole is worn out

Over time, the rubber gasket can thin out and eventually wear out. When it does, it will cause the tank's sealing to weaken. The best solution is to replace the old rubber gasket with a new one.
