LA pipe materials by era

Before about 1950: galvanized steel supply lines were standard in the bungalows and duplexes of Highland Park, Echo Park, West Adams, Boyle Heights, Mid-City and Hollywood. Galvanized rusts inside, narrowing until pressure drops and water runs brown. Threaded joints are the usual failure points, often in the crawl space.

1950s and 1960s: copper became standard in the San Fernando Valley and Westchester tract homes, frequently under the slab. Copper lasts, but pinhole leaks appear with age.

Late 1970s to mid 1990s: some LA homes and condos received polybutylene, a gray plastic pipe known for fitting failures and often recommended for replacement.

Recent decades: PEX and copper repipes, plus new lines in ADUs.

Common LA pipe problems

  • Pressure loss and rusty water from galvanized pipe
  • Pinhole leaks in older copper, especially hot lines
  • Leaks at old shut-off valves when they are finally turned
  • Pipes stressed by hillside soil movement or earthquakes
  • Mixed materials patched over the years in older duplexes

Spot repair or repipe

One leak in sound pipe suits a spot repair. Several leaks, narrowed galvanized, or polybutylene usually point toward a repipe in PEX or copper through walls and the attic. In the City of Los Angeles, repiping generally needs an LADBS permit. Ask about drywall patching, fixture reconnection and whether the permit is included.

Pressure regulators

Many LA homes, especially in lower-elevation areas fed by high street pressure, have a pressure reducing valve near the main. When it fails, high pressure stresses pipes and hoses. Banging pipes and dripping relief valves are clues. Related: leak detection in Los Angeles, Los Angeles plumbing guide and the statewide pipe repair guide.

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
