Water supply lines are pipes that transport water from a main source, such as a water treatment plant or well, to homes and businesses. These lines are essential for providing clean and safe drinking water, as well as water for cooking, cleaning, and other daily activities. Typically made from materials like PVC, copper, or PEX, water supply lines are buried underground or run through walls. They connect to fixtures like sinks, toilets, and showers, ensuring that water is readily available where it is needed. Proper maintenance of these lines is crucial to prevent leaks and ensure efficient water delivery.
