How to Fix a Constantly Running Old Toilet Tank: A Step-by-Step Guide

In real life, if the old-style toilet tank at home keeps running, how can it be repaired？

How to Repair a Constantly Running Old Toilet Water Tank：

1、The Flush Valve Is Not Sealing Properly

If an old toilet water tank is constantly running, it may be because the flush valve is not sealing properly. In this case, quickly press the toilet button, as this will reset the button to normal. This issue indicates that the toilet is equipped with a button mechanism. When flushing, if the button does not immediately return, the flush valve might remain open. Consequently, the water tank will continue to fill, leading to a continuous running sound.

2、Faulty Components in the Water Tank

Another possibility is that a component in the water tank has malfunctioned. If the float has filled the tank but the water tank remains in fill mode, there may be a leak. Check the sensitivity of the float; if it is faulty or stuck, it should be removed and replaced or repaired. There could also be issues related to the drainage system, particularly if there is a loose connection at the water pipe junction, which can lead to continuous running.

How to Resolve a Constantly Running Toilet：

After using the toilet, check if the switch has returned completely. If running water is a frequent issue, the button may be worn out and needs to be replaced with a new one or a new switch.

Next, inspect the float inside the water tank for any faults. If there are issues, replace the float with a new one or have a professional check and repair it. Additionally, regularly examine the drainage pipes, especially at the junctions, ensuring that seals are intact to prevent ongoing water flow from the toilet.
