What is different about water line repair and replacement in Philadelphia?
The line typically comes through the front basement wall to the meter. Check the pipe there: lead is dull gray, scratches to a shiny silver and is not magnetic. If it is lead and it is leaking, replacing the full line is the better choice than patching, because cutting into lead pipe can raise lead levels at the tap.
A leak between the main and the house often shows as water in the street or sidewalk, a hissing sound at the meter with everything off, or a notice from the Water Department. In a rowhouse the service runs under the front steps and sidewalk, so replacement is often done by pulling new pipe through instead of trenching.
