How do I know if my water main line is leaking?
Common signs include consistently damp or soggy spots in your yard, a sudden drop in water pressure, discolored water, or an unexplained increase in your water bill. A professional leak detection service can confirm the source.
What is the typical lifespan of a water main line?
The lifespan varies depending on the material; galvanized steel can last 20-50 years, while copper and PEX can last 50 years or more. Factors like soil conditions and water chemistry can also influence its longevity.
