New Orleans water comes from the Mississippi River and goes through treatment that leaves mineral content and sediment. That sediment accumulates in pipes, water heaters, and valve seats over time. When valves close, sediment particles get caught in seals, preventing complete shutoff. This causes pressure fluctuations that make pipes rattle. The minerals also build up inside galvanized pipes, narrowing the interior diameter and increasing water velocity. Higher velocity means more turbulence and more noise. Homes in areas with older distribution lines, like parts of Gentilly and the Bywater, see heavier sediment loads because the infrastructure sheds particles as it ages.
New Orleans operates under Orleans Parish plumbing codes that specify proper installation methods for supply lines, pressure regulation, and water hammer prevention. These codes exist because local conditions demand them. A plumber licensed to work in Orleans Parish understands these requirements. Liberty Plumbing techs know the inspection standards and install systems that pass scrutiny. When we secure loose pipes or install arrestors, we do it according to code. This protects you if you ever need a permit for other work or if an insurance adjuster inspects your plumbing after a claim.
