Water lines, also referred to as water pipes or supply lines, are an essential part of a home or commercial property’s plumbing system. These lines carry fresh water from the main water supply to various parts of the building. More specifically, the main water line connects to a municipal water supply or a private well and runs either underground or inside walls, ensuring the water reaches different areas of the property efficiently. This crucial network of pipes is responsible for delivering clean water to faucets, showers, toilets, and other water fixtures throughout the home or building.
