Water line repair in Philadelphia, PA
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.

Local conditions
Water line repair in Philadelphia: what's different
Philadelphia owners are responsible for their water service lines, and the city has many older lead lines. A leak in the line under the sidewalk or street is the owner's to repair.
The city offers programs to help replace lead lines. Permits come from the Department of Licenses and Inspections.
Water service lines in older rowhouse neighborhoods often run under the sidewalk to a curb stop near the street, and a leak there may show up as a wet spot on the sidewalk or low pressure in the house. Repair often involves excavation and restoring the sidewalk.

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.
