Hawthorne's postwar homes were often plumbed with galvanized steel supply pipe, and some still have it today. Galvanized pipe corrodes from the inside, so the signs are gradual: weaker pressure at faucets, rusty or brown water after the taps sit, and eventually small leaks at threaded joints. Homes that were updated may have copper or PEX in some areas and old pipe in others.
Some older Hawthorne houses sit on raised foundations with a crawlspace, which makes it easier to reach pipes under the floor. Others are on slabs, where a leak may show as a warm or damp spot on the floor. Apartment buildings add another layer, since a leak inside a wall can affect a neighboring unit, and repairs to shared lines are usually the owner's responsibility.
When you call, share the pipe material if you know it, the symptom and whether you rent or own. Ask the contractor whether a spot repair will hold or whether a section should be replaced, and request a written scope with fees. Our California pipe repair page explains the general options.

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
