Water line leaks in Philadelphia: the owner's pipe starts at the main
Updated · Editorial team; not yet technically reviewed
Short answer
In Philadelphia, water becomes the customer's responsibility once it leaves the city-owned main in the street. The owner is responsible for the ferrule at the main, the service pipe, the curb stop and its box, the supply pipe into the house, and the valves around the meter. If PWD finds a leak, it issues a Notice of Defect, and its HELP loan can pay for the repair at 0% over five years.
What's different in Philadelphia
Once drinking water leaves the city-owned main in the street, it becomes the customer's responsibility, including the piping to the home and inside it. [1]
The owner is responsible for the ferrule (connection to the main), the water service pipe, the curb stop and curb stop box, the water supply pipe into the house, and the meter supply valves. [2]
Owners with connections of 2 inches or less must maintain them in good repair, and after a Notice of Defect PWD offers a five-year, zero-interest loan; call (215) 685-4901. [1]
