When to call, and what to do first

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

  • Repiping

    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 Hayward: Old clay laterals crack with soil movement near the fault.

    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 Heater Replacement

    Why it comes up in Hayward: Seismic strapping and venting are updated on replacement.

    Signs:
    Water around the tank base, rusty hot water, a tank past 10 years
    Urgent when:

    Turn off gas or power and close the cold-water valve
    Repair or replace:
    Leaking tank: replace. Failed part on a younger tank: repair

Why Hayward homes need these repairs

Hayward is an East Bay city of post-war tract homes in the flatlands and hillside neighborhoods above, crossed by the active Hayward Fault. All of its water comes from San Francisco's Hetch Hetchy system, which is soft, so scale is rare; aging pipes, sewer laterals and earthquake readiness drive most calls.

Pipe problems in Hayward's 1970s homes

The median home in Hayward was built in 1974, and 59% of homes predate 1980. Homes from that era were typically built with copper supply, early plastic (ABS or PVC) drains, some cast iron, which is where leaks, low pressure and drain problems usually start as they age.

Median home: 1974
1900195020002025
  • Galvanized steel supply (1900–1960)
  • Copper supply (1950–2000)
  • Polybutylene (some homes) (1978–1996)
  • PEX / CPVC (1995–today)
Typical supply-pipe materials by construction year. Many older homes have been partly repiped since.

Hayward's water supply and your plumbing

Hayward has bought all of its water from the San Francisco Public Utilities Commission since a 1962 agreement; about 85% comes from the Hetch Hetchy watershed in Yosemite and 15% from the Alameda watershed. [1]

Hayward's water travels mostly downhill from the Sierra Nevada by gravity rather than by energy-intensive pumping. [2]

Hayward plumbing questions

Should old pipes in a Hayward 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 Hayward: Post-war tract homes still have galvanized lines that rust and lose pressure.

Can recurring clogs in Hayward 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 Hayward: Old clay laterals crack with soil movement near the fault.

Is Hayward's water hard or soft?

Soft. Hetch Hetchy snowmelt has very few minerals, so most Hayward homes don't need a softener.

How do I earthquake-proof plumbing in Hayward?

Double-strap the water heater, add a seismic gas shutoff valve if you have gas, and use flexible connectors on gas appliances. These are cheap and matter on the Hayward Fault.

Who supplies Hayward's water?

The city buys it all from the San Francisco Public Utilities Commission, mostly from Hetch Hetchy in Yosemite.

Why do older Hayward homes have low pressure?

Galvanized pipe from the 1950s rusts inside and narrows. A repipe in copper or PEX restores pressure.
