Common plumbing issues we see in La Verne

La Verne's long history left it with three distinct housing layers (Old La Verne, the central tracts and the foothill custom homes), and each has its own common problems.

  • The Craftsman and citrus-era homes in Old La Verne still carry original galvanized and cast iron, so repipes are common downtown.
  • The 1960s-80s central tracts are aging into slab leaks and galvanized failures.
  • Custom homes toward Marshall Canyon get the same high water pressure as the rest of town, so yearly regulator testing matters there too.
  • Hard water scales heaters across town, and mature trees along the older streets work roots into sewer lines.

Working in La Verne

The La Verne plumbing landscape.

Housing stock

La Verne started in 1887 as "Lordsburg," incorporated in 1906, and took its current name in 1917; it was the "Heart of the Orange Empire" and is still home to the University of La Verne (founded 1891). That long history gives it three layers of housing: Craftsman and citrus-era homes in Old La Verne near downtown, 1960s-80s tracts through the center as the groves were cleared, and custom homes up toward Marshall Canyon and the San Gabriel foothills. Each era plumbs differently.

Water service

La Verne water comes through the City of La Verne and, in parts of town, Golden State Water Company. Like the rest of Southern California, La Verne has high water pressure, so regulators matter. It's hard water, so mineral scale builds up in water heaters and on fixtures.

Local landmarks & areas we know

If you're near the University of La Verne, Marshall Canyon Regional Park, Brackett Field Airport or the Bonita High School area, you're in our regular service area.

In La Verne specifically, the most common calls we get are for historic Craftsman repipes in Old La Verne, and for slab leaks and worn-out pressure regulators across town. But the full range of work we do in La Verne includes:

Urgent Calls

Active leaks, no water, and sewer backups: we dispatch to La Verne 24/7.

Water Heater Service

Tank, tankless, gas, electric, hybrid. La Verne's older homes often need code-update work around the unit during replacement.

Slab Leak Repair

Our acoustic and electronic detection pinpoints the leak, so repairs need little demolition.

Gas Line Repair

Natural gas service across La Verne, residential and commercial. Every job is pressure-tested and leak-checked before the gas goes back on.

Drain Cleaning & Hydrojetting

In La Verne's older homes, the sewer laterals are often cast iron or clay, with root intrusion. Cable for blockages, hydrojet to clear roots and grease. Camera inspection on every main line.

Whole-Home Repipe

Aging galvanized lines are a frequent culprit in La Verne's older homes. Our repipes use PEX or copper and run in phases, and we patch any drywall we open.

Sewer Line Replacement

Original clay laterals are common in older La Verne neighborhoods. When they crack or roots get in, we line them in place or replace them. Cast-iron, clay, ABS: trenchless when possible.

Backflow Testing

Annual testing & certification for City of La Verne or Golden State Water Company requirements, depending on your provider. We file the paperwork directly with your water provider on your behalf. We also install and repair backflow preventers.
