Water Line Repair and Replacement in New Orleans, LA
Many older New Orleans homes are connected to the water main by lead service lines. The Sewerage and Water Board has been inventorying service line materials, so check what is known about your address. If a lead line is leaking, replacing all of it is better than patching.

What is different about water line repair and replacement in New Orleans?
Settling ground is hard on service lines here, as it is on sewers: lines stretch and joints loosen as the soil moves, and street and sidewalk work can disturb them. Disturbing a lead line can release particles, so if there has been construction on your block, follow the board's guidance on flushing and filters.
On a raised house you can usually see where the line comes up from the ground to the floor, which makes identifying the material simple. Ask the Sewerage and Water Board how ownership of the line is divided and whether any replacement assistance applies. Boil water advisories are a separate matter and do not mean your own line is faulty.

Water Line Repair and Replacement questions from New Orleans
How can I tell if my New Orleans home has a lead service line?
Look at the pipe where it comes out of the ground under the house or at the meter. Lead is dull gray, soft enough to scratch shiny and not magnetic. The Sewerage and Water Board can tell you what its records show.
Does a boil water advisory mean my pipes are bad?
No. Advisories are issued when pressure in the public system drops, which could let contaminants in. It concerns the whole system, not your home's plumbing.
