Hacienda Heights

Older lines in a hillside community

The land that became Hacienda Heights was subdivided for avocado, citrus and walnut orchards in 1913. Suburban housing spread across it in the 1950s, and the community took its current name in 1961. Voters turned down becoming a city in 2003, so it remains unincorporated Los Angeles County.

The Puente Hills form a green belt along the southern and western edges, with Workman Hill rising to about 1,391 feet. Hsi Lai Temple, completed in 1988, sits on a hillside within the community. Streets that wind up into those hills are where trenching takes the most planning.

Local problems

What fails most often in Hacienda Heights

Galvanized steel from the 1950s and 1960s

Homes from the first building wave are prime candidates for corroded steel lines, low pressure and rusty water.

Steep driveways and terraced yards

Lines on hillside lots need trenches planned around grade and retaining walls.

Repeat leaks on old pipe

Once one section of an older line fails, others usually follow.

Planning the job

Planning work on an older Hacienda Heights home

For a house from the 1950s or 1960s, we start by confirming what the line is made of. If it is the original steel, a single repair rarely holds for long, and we will tell you so. If it was already replaced with copper at some point, a targeted fix may be all you need.

Hillside streets add a second layer of planning. Driveways that rise from the street, retaining walls and mature trees all change where the trench can go. Because the community is unincorporated, the permit and inspection run through Los Angeles County.

We also ask about past work. Many homes here have been remodeled over the decades, and an addition or a patio built over the old route is a common reason to run the new line on a different path.
