When to call, and what to do first

For the problems Fullerton homeowners call about most, and why they come up here:

  • Repiping

    Why it comes up in Fullerton: 1920s–50s homes still carry galvanized supply pipe.

    Signs:
    Rusty water, falling pressure, repeated pinhole leaks
    Urgent when:
    Leaks keep recurring in different places
    Before help arrives:
    Note where leaks and rust appear; check the pipe at the water heater
    Repair or replace:
    One leak: repair. Failing pipe throughout: repipe
  • Sewer Line Repair

    Why it comes up in Fullerton: Clay laterals under mature trees crack and fill with roots.

    Signs:
    Several drains slow at once, gurgling, sewage smell
    Urgent when:
    Sewage backing up into a tub, shower or floor drain
    Before help arrives:
    Stop running water; don't use chemical drain cleaners
    Repair or replace:
    One break: spot repair or lining. Collapsed line: replace
  • Water Softener Installation

    Why it comes up in Fullerton: Groundwater-heavy supply is hard.

    Signs:
    White scale that clogs aerators and showerheads, spotty glasses, a noisy water heater
    Urgent when:
    Rarely urgent; scale builds slowly
    Before help arrives:
    Check your water hardness in the utility's water quality report
    Repair or replace:
    Hard water damaging heaters or fixtures: a softener protects them

Why Fullerton homes need these repairs

Fullerton is a north Orange County college town with 1920s–30s Spanish and Craftsman homes near downtown, post-war tracts and hillside neighborhoods. Most of its water is Orange County basin groundwater pumped by city wells, and old galvanized pipe, clay laterals and hard water drive the calls.

Plumbing problems common in Fullerton's older homes

The median home in Fullerton was built in 1969, and 71% of homes predate 1980. Homes from that era were typically built with copper or galvanized supply, cast iron drains, clay or cast iron sewer laterals, which is where leaks, low pressure and drain problems usually start as they age.

  • Galvanized steel supply (1900–1960)
  • Copper supply (1950–2000)
  • Polybutylene (some homes) (1978–1996)
  • PEX / CPVC (1995–today)

Fullerton's water supply and your plumbing

Fullerton's water is mostly Orange County basin groundwater blended with Metropolitan Water District imports from the Colorado River and State Water Project; the city currently relies on about 77% groundwater and 23% imported water. [1]

About 75% of Fullerton's water supply is provided by 10 city groundwater wells. [2]

Fullerton plumbing questions

Should old pipes in a Fullerton home be repaired or replaced?

One leak in otherwise sound pipe is usually repaired; when galvanized or failing pipe leaks in several places, repiping costs less over time. Why it comes up in Fullerton: 1920s–50s homes still carry galvanized supply pipe.

Can recurring clogs in Fullerton mean a sewer line problem?

Yes. When several drains back up together, the main sewer line is the likely cause, and a camera inspection shows whether it's roots, a sag or a break. Why it comes up in Fullerton: Clay laterals under mature trees crack and fill with roots.

Where does Fullerton's water come from?

Mostly from city wells in the Orange County groundwater basin, blended with imported Colorado River and State Water Project water.

Is Fullerton water hard?

Yes. Both the groundwater and the imported water carry minerals, so scale is common.

Should I repipe a Golden Hill 1930s home?

If it still has galvanized pipe, yes: low pressure and rusty water are the signs. Copper or PEX are standard replacements.

Why do Sunny Hills homes have high water pressure?

Hillside streets can carry high pressure. A regulator near 60 psi protects pipes and fixtures.
