Much of the region’s water is imported from the Colorado River, Northern California and the Eastern Sierra, and much of it is moderately hard to hard, which builds scale in water heaters and fixtures. California code requires water heaters to be strapped against earthquakes, and replacements generally require a permit. Hillside homes add long, steep sewer laterals and pressure-regulation challenges.

What makes Los Angeles plumbing different
Slab leaks in copper
Copper lines under mid-century slabs develop pinhole leaks; rerouting through attics or walls is common after a second leak.
Seismic strapping and permits
Water heaters must be strapped against earthquakes, and water heater replacement typically requires a permit.
Hard imported water
Moderately hard to hard water scales water heaters, tankless units and fixtures.
Hillside homes
Steep lots mean long laterals, pressure-reducing valves and challenging access.

Los Angeles plumbing questions
Why are slab leaks so common in Los Angeles?
Many LA homes were built on slabs with copper supply lines underneath. Over decades, water chemistry, abrasion and soil movement cause pinhole leaks.
Do I need a permit to replace a water heater in Los Angeles?
Water heater replacement typically requires a permit, and the installation must include seismic strapping and proper relief valve discharge.
Is Los Angeles water hard?
Much of the region’s imported water is moderately hard to hard. Hardness varies by utility, so check your provider’s water quality report.
Should I reroute or repair a slab leak in LA?
For a first leak in otherwise sound pipe, repair can make sense; after repeated leaks, rerouting through the attic or walls avoids more concrete work.
How do I shut off water after an earthquake?
Know where your main shutoff is — often near the front of the house or at the meter — and keep a meter key or wrench handy.
