Water line repair in Washington, DC
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.

Water line repair for Washington homes
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.

Water line repair in Washington: what's different
Many older D.C. rowhouses are still served by aging water service lines, and some are lead. DC Water runs a lead service line replacement program, and leaks in older lines show up as low pressure, a wet spot near the sidewalk or a jump in the water bill.
When the service line is replaced, older galvanized or lead-soldered pipe inside the house often remains, and replacing it at the same time gets the full benefit. Rowhouse service lines usually run under the front yard or sidewalk, so repairs involve public space permits along with the D.C. Department of Buildings permit.

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.
