Next you will find descriptions that will help you understand and answer the remaining questions:
The federal Environmental Protection Agency (EPA) defines “lead service line” as a portion of pipe that is made of lead, which connects the water main to the meter and from the meter to the building inlet. A lead service line may be owned by the water system, by the property owner, or both.
The following are considered to be lead service lines (LSL) or "galvanized requiring replacement" (GRR) lines:
- if your service line galvanized iron/steel
AND
- was ever downstream of any lead service line
OR
- a service line made of an unknown material
If the only lead material serving the home is a lead gooseneck, pigtail, or connector, and it is NOT a galvanized service line, then the service line is not a lead service line.
