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 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, 811 must be called to mark gas, electric and communication lines.

How to find and test your main water shutoff
Look where the water line enters the house, usually through the basement or crawl space wall facing the street, next to the water meter. Test it once a year by closing it and confirming water stops at a faucet, so you know it works before a pipe bursts.

High water bill? How to find a hidden leak
Turn off every fixture and watch the meter's leak indicator for 15 minutes. If it moves, put dye in each toilet tank, check the water heater and irrigation, then call for leak detection if you still can't find it.
