Plumbing conditions in California
California has varies from mild coast to hot inland valleys, with dry summers and winter atmospheric-river storms. Large stocks of post-war slab and raised-foundation homes, many with galvanized or original copper lines and clay or Orangeburg sewer laterals.
Freezing weather is rare in California, so the main plumbing stresses are heat, water chemistry and ground movement rather than frozen pipes.
Much of California has hard water. Scale builds up in water heaters and fixtures over time, which shows up as popping noises in the tank, weak shower flow and crusty aerators.
Common plumbing problems in California
- Hard-water scale in water heaters and fixtures
- Atmospheric-river flooding
- Earthquake-related pipe damage
- Slab leaks
- Aging drain and sewer lines in older neighborhoods

Cities we serve in California
Each city page covers local conditions. Towns without a page are served too.
Los Angeles, CA
Los Angeles County
Los Angeles has huge numbers of 1920s to 1960s homes with galvanized supply lines and clay sewer laterals, plus slab homes in the Valley where slab leaks are common.
San Diego, CA
San Diego County
San Diego's water is hard, so tankless heaters and fixtures scale quickly, and older homes in North Park and Clairemont often need repiping.
San Jose, CA
Santa Clara County
San Jose's post-war tract homes are reaching the age where original copper and cast-iron drains fail, and winter storms can flood low-lying areas near creeks.
San Francisco, CA
San Francisco County
San Francisco's dense, older housing means stacked units, shared drain lines and older cast iron, where one leak can affect neighbors below.
Sacramento, CA
Sacramento County
Sacramento sits at the meeting of two rivers behind levees, and its many mature street trees push roots into older clay sewer laterals.
Fresno, CA
Fresno County
Fresno's hot Central Valley summers and hard water are tough on water heaters, and many 1950s to 1970s homes have slab plumbing.
Oakland, CA
Alameda County
Oakland's hillside homes have long, steep sewer laterals, and East Bay cities require lateral inspections or upgrades in some property transfers.
Long Beach, CA
Los Angeles County
Long Beach has many 1920s to 1950s homes near the coast, where salt air and older galvanized pipe combine to cause corrosion and low water pressure.
Bakersfield, CA
Kern County
Bakersfield's very hot summers and hard water shorten water heater life, and its newer subdivisions are mostly slab builds with PEX.
Riverside, CA
Riverside County
Riverside's inland heat and hard water mean frequent water heater and softener service, and older neighborhoods have clay sewer lines lifted by tree roots.
