Plumbing service throughout Santa Ana

Santa Ana is one of Orange County’s most densely populated and historic cities. Floral Park has 1920s craftsman homes with their original galvanized supply lines, the Harbor District has mid-century apartment buildings, and there is newer construction near South Coast Metro.

Older, denser housing means aging galvanized supply lines, original clay sewer laterals, and cast iron drain stacks in multi-unit buildings. The problems that follow are low water pressure, drains that back up again and again, and sewer lines that have been patched before.

The work we are called for most in Santa Ana is sewer camera inspection, full-house repiping, drain clearing, and water heater repair. We also work on multi-family buildings, including shared sewer lines and building-wide drain clearing.

What Santa Ana homeowners should know

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

  • Built before 1940Galvanized steel supply and cast iron drains, in Floral Park, French Park, and Downtown. Both are past their rated life, and clay laterals here are exposed to roots from street trees.
  • 1940s to 1970sCopper supply with cast iron or ABS drains. Hard water speeds up pinhole leaks in copper, and aging cast iron stacks in apartment buildings clog often.
  • Built after 1980Plastic supply and drain lines, around South Coast Metro and newer tracts. More resilient, though slab foundations still carry slab leak risk.

Water hardness

The City of Santa Ana supplies the water, which 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 Santa Ana, 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 unincorporated areas of ZIP 92705 may fall under Orange County instead of the city; we confirm which office applies. Unpermitted work can cause problems when you sell the house or file an insurance claim.

How much does a plumber cost in Santa Ana?

It depends on the job. Every job is priced in writing before work begins, so you can decide with the number in front of you.

Do you work on apartment buildings and multi-family properties?

Yes: multi-unit repipes, shared sewer systems, and building-wide drain clearing. Call for a multi-family estimate.

Why is my water pressure low?

In Santa Ana the most common cause is galvanized supply pipe that has corroded and narrowed inside, which is typical in homes built before 1970. A failing pressure regulator valve is another. The fix ranges from replacing the regulator to a repipe.

How does Santa Ana's hard water affect my plumbing?

Minerals speed up sediment in water heaters, scale inside pipes, and corrosion at fixture valves. Flush the water heater yearly, and consider a softener on older copper or galvanized lines.

What customers say

★★★★★

Great experience with Miguel and Steven! Fixed my stubborn kitchen sink clog. Very informative and respectful of my home in addressing the issue. Highly recommend!

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!

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.
