What Is a Water Service Line?

Your water service line is the underground pipe that connects your home to the municipal water supply at the street. Over time, these lines—especially older galvanized or copper pipes—can crack, corrode, or collapse, causing serious problems both inside and outside your home.

Common Signs of a Failing Water Service Line

  • Sudden or ongoing low water pressure
  • A sharp increase in your water bill with no change in usage
  • Wet or muddy patches in your front yard
  • Discoloration or sediment in your tap water
  • Constant sound of water running (even when no fixtures are on)
  • Water leaking or flooding near the meter or where the pipe enters your home

If you notice any of these signs, it’s important to act fast. Left unaddressed, a damaged water service can lead to extensive property damage and significant utility costs.


Water Service Repairs vs. Replacements

Depending on the condition and material of your existing line, we’ll recommend either a targeted repair or a complete water line replacement:


Spot Repairs:

If the damage is isolated—such as a pinhole leak or small crack—we may be able to excavate and repair the damaged section of pipe.

Full Replacement:

If the older piping is brittle or has to many leaks, a full service replacement may be the best option.
