The answer to 'how to clean water line' is to periodically flush and clean your home's water supply lines. This helps remove any buildup of sediment, minerals, or other contaminants that can accumulate over time and affect water quality and pressure.
To clean your water lines, start by turning off the main water supply to your home. Then, open the highest and lowest faucets in your home to drain the water from the pipes. Once the pipes are empty, use a garden hose to flush the lines by running water through them for several minutes. You can also use a water line cleaning solution or vinegar to help dissolve any buildup. Finally, turn the water back on and check for any leaks or issues.
