Leaks, pipes & freezing

Main water line repair

The water service line runs from the curb stop near the street to your house, buried below the frost line. A leak shows up as a soggy patch in the yard, low pressure throughout the house, or a meter that never stops. Repair means finding the leak, then fixing that spot or replacing the line.

About water line repair

Older Front Range homes may still have galvanized or even lead service lines, and many utilities are now inventorying them. Newer homes typically have copper or PE (polyethylene) tubing. Frost heave and expansive clay soil can stress all of them.

The homeowner usually owns the line from the curb stop to the house. Before digging, Colorado 811 must be called to mark gas, electric and communication lines.

What affects the cost

Every job is priced by the plumber after they see it. These are the things that move the price most. Ask for the price before work starts.

  • Spot repair versus full replacement
  • Line length and depth
  • Trenchless boring or open trench
  • Driveways, walks and landscaping above the line
  • Permit and tap fees

Water line repair questions

Do I own the water line to my house?

Usually from the curb stop (a shutoff near the property line) to the house. The utility owns the main and the connection up to the curb stop. Your water provider can confirm the boundary for your address.

How deep is the water line in Colorado?

Service lines are buried below the local frost depth, commonly between 4 and 6 feet on the Front Range. Exact requirements are set by each water provider and building department.

What are the signs of a broken water service line?

A wet or sunken strip of yard between the street and the house, low pressure at every fixture, and a meter that moves when everything is off.

What is trenchless water line replacement?

A new line is pulled or bored underground between two small pits, avoiding a full trench across the lawn or driveway.

Does Denver Water replace lead service lines?

Denver Water runs a lead service line replacement program for customers with lead lines. If you receive a notice, the program can cover the replacement.

Do I need a permit to replace my water line?

Usually yes, from the city or county and sometimes from the water provider. Colorado 811 must also be called to mark buried utilities before digging.
