Common plumbing issues we see in Chino Hills

Chino Hills is mostly 1980s-2000s master-planned construction, and that shapes most of what we get called for here.

  • Slab leaks are a common call. Copper lines under the slab can develop leaks over time; we find them with acoustic and electronic detection and repair with as little demolition as possible.
  • Water pressure runs high across Southern California and wears regulators out, so we suggest having yours tested once a year.
  • The original 1920s Los Serranos subdivision has older lines that predate the master-planned build-out, and they show their age.
  • Hard water scales up water heaters across the city.

Working in Chino Hills

The Chino Hills plumbing landscape.

Housing stock

Chino Hills was rolling ranch and equestrian land until San Bernardino County's 1979 Specific Plan opened it to development; the city didn't incorporate until December 1991. So the housing is overwhelmingly 1980s-2000s master-planned construction, neighborhoods like Butterfield Ranch and Rolling Ridge, on copper. The exceptions are the older 1920s-era Los Serranos subdivision and some custom estates up in Carbon Canyon. Newer stock means fewer galvanized failures here.

Water service

Water in Chino Hills is handled by the City of Chino Hills. Like the rest of Southern California, Chino Hills gets high incoming water pressure, so pressure regulators matter. Its water is a blend of imported State Water Project water and local groundwater, hard enough that mineral scale builds up in water heaters and on fixtures.
