Water service lines in Los Angeles: no lead found
Updated · Editorial team; not yet technically reviewed
Short answer
LADWP's federally required service line inventory, completed for the October 2024 deadline, found no lead service lines and no galvanized lines requiring replacement anywhere in its system, including privately owned customer lines. So LA service line work is about leaks and age rather than lead, though interior plumbing in older homes can still contain lead solder or galvanized pipe.
What's different in Los Angeles
LADWP completed the initial lead service line inventory required by the EPA's Lead and Copper Rule Revisions, due October 16, 2024. [1]
After historical records review and field investigations, LADWP determined there are no lead service lines or galvanized lines requiring replacement in its system, including privately or customer-owned lines. [1]
The review used construction and plumbing codes, water system records including GIS data and capital plans, inspection records, and state-provided billing and tax assessor data. [1]
What the inventory doesn't cover
- Interior galvanized pipe in pre-1960 homes, which can rust and restrict flow; see when to repipe a house.
- Lead solder on older copper joints inside the house.
- Old brass fixtures and valves.
Leaks on the LA service line
The line from the meter to the house can still leak from age, roots or earth movement. Start with a meter test and leak detection; for sewer issues, see LA sewer lateral repair.
