The answer to 'toilet leaking water' is that there are several common causes, including a faulty toilet flapper, a problem with the fill valve, or a crack in the toilet tank or bowl. Symptoms may include water pooling around the base of the toilet, a constantly running toilet, or the water level in the tank dropping.
To troubleshoot and fix a leaking toilet, you can try simple DIY repairs like replacing the flapper or fill valve. However, if the issue is a crack or a more complex problem, it's best to call a professional plumber to properly diagnose and repair the issue to prevent further water damage.
