Water supply lines are pipes that transport fresh water from a source, such as a water treatment plant or well, to homes and businesses. These lines are essential for providing clean water for drinking, cooking, and sanitation. They are typically made of materials like PVC, copper, or PEX to ensure durability and safety. In residential settings, water supply lines connect to fixtures like sinks, toilets, and showers. Proper installation and maintenance of these lines are crucial to prevent leaks and ensure a reliable water supply. Regular inspections can help identify issues before they lead to significant problems.
