Plumbing service throughout Orange

You can read the history of Orange in its plumbing. Around the Plaza in Old Towne there are Victorian homes from the 1880s, craftsman houses from the 1910s and 1920s, and ranch homes from the 1940s and 1950s, many with clay sewer laterals and galvanized supply lines.

Farther out, the homes get newer, all the way to Santiago Hills in the 1990s. That range means our plumbers see every generation of pipe and the way each one fails, from drain clearing in East Orange to sewer replacement and repiping in the historic core.

What Orange homeowners should know

Your home's pipes, by the year it was built

  • Built before 1940Galvanized steel supply and cast iron drains in Old Towne. Original clay sewer laterals let roots in and separate at the joints.
  • 1940s to 1970sCopper supply with cast iron or ABS drains. Hard water can cause pinhole leaks in copper, and slab foundations carry slab leak risk.
  • Built after 1980Plastic pipe throughout. Long sewer laterals on large lots still attract roots.

Water hardness

Orange's water is a blend of local groundwater and imported water, and it is hard. The city publishes the current figure in its annual water quality report. Regular water heater flushing helps, and a softener is worth considering on older copper or galvanized lines.

Permits

In Orange, jobs like water heater replacement, sewer repair, gas line work, and whole-home repiping generally require a city permit and inspection. We tell you at the estimate when one applies. Homes in the Old Towne Historic District may also need design review for exterior plumbing work, which we raise at the estimate. Unpermitted work can cause problems when you sell the house or file an insurance claim.

Plumbing questions from Orange

Do you work on historic homes in Old Towne Orange?

Yes. Homes from the 1880s through the 1940s have clay laterals and galvanized or early copper supply lines, and we do sewer replacement, repiping, and water service replacement on them. We flag any historic district review at the estimate.

How quickly can you get to a home in Orange?

We serve all five Orange ZIP codes and give you an honest arrival window when you call. Burst pipes, sewage backups, and gas leaks are sent out first.

My Orange home was built in the 1950s or 1960s. What should I expect?

Copper supply lines that can develop pinholes from hard water, cast iron drains that corrode inside and slow down, and clay sewer laterals that let roots in. Start with a sewer camera inspection.

Why does my sewer keep backing up?

In Old Towne and the older parts of 92867, the usual cause is tree roots in a clay lateral that can be more than 60 years old. A camera shows whether it is roots, grease, a collapse, or a low spot, and the fix follows from that.

How hard is the water in Orange?

It is hard, which means sediment in water heaters, scale in pipes, and faster wear on valves. Flush the water heater once a year, and consider a softener for older copper or galvanized plumbing.

What customers say

★★★★★

I had a plumbing issue that needed to be repaired sooner than later. Miguel came out and knew how to fix it immediately. Miguel was professional, friendly and knowledgeable. I won't hesitate to call them in the future.

I had an excellent experience with SoCal 1 Plumbing! Eliass came out to clear a blockage in my kitchen line by snaking it through the outside wall clean-out, and everything was done efficiently and with great care. He also installed new tubular drains under my kitchen sink to stop the leaks I’d been dealing with. The work was high-quality, and they even provided a 1-year warranty on parts and labor, which gave me peace of mind. Highly recommend their professional and reliable service!
