Plumbing in New Orleans: what locals should know
Water quality
The water in New Orleans is moderately hard. Most plumbing systems handle it fine, but if you're installing a new tankless water heater, ask about the warranty requirements — some require a water treatment system.

New Orleans rarely freezes, but when it does, exposed pipes are especially vulnerable because homes here aren't built for cold weather. Insulate outdoor pipes and know your shutoff valve location just in case.

Local tip
Many New Orleans homes built in the 1970s-80s have polybutylene (gray plastic) water pipes, which are prone to unexpected failures. If your home has them, most plumbers recommend proactive repiping before a catastrophic leak.
