What Causes Water Main Breaks?

Water mains are made of cast iron or plastic pipes that run underneath city streets to provide clean drinking water to homes and businesses. Despite their durability, these pipes are subject to wear and tear over time due to age and corrosion. They can also be compromised by extreme weather conditions such as freezing temperatures or heavy rains. When the pressure from these circumstances is too great for the pipe to handle, it can rupture, resulting in a water main break.
