The answer to 'water line making gurgling noise' is that a gurgling sound in your water lines is usually a sign of a blockage or air in the pipes. This can be caused by a number of issues, such as a clogged drain, a problem with the water heater, or even a break in the water line.
Some common symptoms of this issue include slow draining sinks, low water pressure, and the gurgling noise itself. To troubleshoot, you can try plunging the drain, checking for any visible leaks, and ensuring the water heater is functioning properly. If the issue persists, it's best to call a professional plumber to diagnose and fix the problem, as they have the tools and expertise to properly identify and resolve the root cause.
