Many Pacoima houses date from the postwar building boom and were plumbed with galvanized steel. That pipe rusts from the inside, narrowing over time and eventually leaking at threads and fittings. Low water pressure, brown water after the taps sit, and repeated small leaks are the usual signs. Homes that have been partly updated may have copper or PEX mixed in with older pipe.
Most houses in the area are single-story on slab or raised foundations. Slab homes can develop leaks under the floor that show as warm spots, damp flooring or a meter that keeps moving. Earthquakes can also stress rigid pipe, especially at connections, so a new leak after shaking is worth having checked. Outdoors, hot Valley summers and irrigation use put wear on hose bibs and yard lines.
When you call, share the pipe material if you know it, where the problem is and whether the water is off. If the leak is on the street side of the LADWP meter, contact LADWP. Ask the contractor about spot repair versus replacing a section, permit needs, fees and a written scope. See our California pipe repair page.

What kind of pipe do you have?
The right repair depends on the material, and in California the material usually tracks the age of the house.
- Galvanized steel (common before about 1960): found in many pre-war and early post-war homes in Los Angeles, Long Beach, South Gate and older Bay Area cities. It rusts from the inside, narrowing the pipe until pressure drops and water runs brown. Leaks often start at threaded joints.
- Copper (common from the 1950s on): used widely in post-war tract homes, often under slab foundations. Long lasting, but pinhole leaks can develop with age and water chemistry.
- CPVC and PEX (more common in recent decades): used in newer construction and repipes. PEX is flexible and resists scale, which makes it popular for reroutes.
- Polybutylene (gray plastic, installed in some homes from the late 1970s to mid 1990s): known for failing at fittings and often recommended for replacement.
Check where the pipe enters the water heater or under a sink to see what you have.
Common pipe problems
- Burst or split pipe: often a failed fitting, a corroded section or physical damage
- Pinhole leaks in copper: small leaks that may show up as a damp spot or a hissing sound
- Low pressure throughout the house: a sign of corroded galvanized pipe or a failing pressure regulator
- Rusty water: usually galvanized pipe or the water heater
- Knocking or banging (water hammer): caused by fast-closing valves or loose pipe straps
- Leaks at old shut-off valves: original valves can seize or drip when finally turned
