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

If the toilet tank experiences a water leak during use, it is essential to identify the cause before proceeding with repairs. Below, I will introduce how to fix an old toilet tank that is continuously running.

Fixing the Constant Water Flow Issue in Your Old Toilet Tank：

1、If the tank has cracks or serious damage, it is recommended to replace the toilet.

2、If the tank has been in use for a long time, causing parts to deteriorate, disassemble the toilet tank to check if the components are intact, and repair or replace any damaged parts.

3、If the flushing valve is loose, simply tighten the flushing valve to stop the leak.

Tips for Toilet Tank Repair

1、First, check for any damage. If the tank has not been subjected to strong impacts or sharp objects and the toilet surface shows no signs of scratches or damage, it is likely not a leakage issue, and it is advisable to create a new toilet tank.

2、After inspection, confirm whether there is any external damage, and check for internal issues. Look at the water level and float ball in the tank. If the water level reaches the maximum, water will be present; if the water level is insufficient, it will stop moving. Also, check for any issues with the float. If there is a problem, you can consider replacing it. For new parts, simply lower the component's position.

3、Once the tank is temporarily drained, check if the sealing ring is damaged and inspect the leakage area. First, remove any scale and other grime from inside the tank, and ensure that the bottom sealing ring is clean. If there are issues, it is crucial to replace it promptly rather than waiting until it completely breaks.

In summary：this concludes the introduction to repairing an old toilet tank that keeps running. It is important to first identify the cause of the issue so that you can determine the appropriate method for repair, which will help avoid unnecessary complications.
