The answer to 'toilet repair making noise' is that a noisy toilet can be caused by a few common issues, such as a worn flapper valve, a loose fill valve, or a problem with the flush mechanism. These problems can lead to water running continuously or intermittently, causing a persistent or intermittent noise.
To troubleshoot the issue, you can start by checking the flapper valve and fill valve to see if they need to be replaced. If the issue persists, the problem may be with the flush mechanism, which may require more extensive repairs. In some cases, the noise may be caused by a problem with the tank or bowl, which would require a more complex repair.
