When to call, and what to do first

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

  • Repiping

    Why it comes up in Pomona: Pre-war homes still carry galvanized 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 Pomona: 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 Pomona: Groundwater-heavy supply is hard and scales fixtures.

    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 Pomona homes need these repairs

Pomona is an older eastern Los Angeles County city with Victorian and Craftsman homes near downtown and post-war tracts beyond. Most of its water is local groundwater from city wells, supplemented by San Gabriel Mountain runoff and imports, and old pipes, hard water and clay laterals drive the calls.

Plumbing problems common in Pomona's older homes

The median home in Pomona was built in 1968, and 66% 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)

Pomona's water supply and your plumbing

Over three-quarters of Pomona's water comes from groundwater, pumped by 38 city wells from two aquifers. [1]

Pomona also uses a small share of surface water from the San Gabriel Mountains and imported water from the Metropolitan Water District and Three Valleys Municipal Water District. [2]

Pomona plumbing questions

Should old pipes in a Pomona 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 Pomona: Pre-war homes still carry galvanized pipe.

Can recurring clogs in Pomona 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 Pomona: Clay laterals under mature trees crack and fill with roots.

Is Pomona's water from wells?

Mostly. Over three-quarters comes from groundwater pumped by city wells; the rest is mountain runoff and imported water.

Do Lincoln Park historic homes need special plumbing care?

Galvanized supply and cast-iron drains are common in homes this old. Interior repiping needs a normal plumbing permit; in a historic district, ask the city before changing anything visible outside.

Why is my Pomona water so hard?

Local groundwater carries calcium and magnesium. A softener or yearly water heater flush limits scale.

Do Phillips Ranch hillside homes have pressure issues?

Yes, hillside elevation can raise or lower pressure. Check the regulator if faucets hammer or flow is weak.
