Plumbing service throughout Irvine

Irvine feels new, but villages like University Park, Turtle Rock, and Woodbridge were built from the 1960s through the 1980s. Many of those homes are now more than 40 years old and still have their original shut-off valves and supply lines.

Hard water reaches even the newest villages on the east side. Irvine Ranch Water District blends groundwater with harder imported water, which scales water heaters, clogs high-efficiency fixtures, and causes pinhole leaks in copper.

Homes across the city sit on slab foundations, so hidden slab leaks are a recurring problem. Our job is to find the cause quickly and lay out your options before any work starts.

What Irvine homeowners should know

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

  • 1960s and 1970sCopper supply and cast iron drains, in University Park and Turtle Rock. Watch for pinhole leaks, drain corrosion, and slab leaks.
  • 1980s and 1990sCopper supply with ABS or PVC drains, in Woodbridge, Northwood, Westpark, and Oak Creek. The copper is reaching the age when pinhole leaks start, and water heaters are near the end of their life.
  • 2000s to todayPEX or copper supply with PVC drains, in Quail Hill, Portola Springs, and the Great Park. The main issue is hard-water scale.

Water hardness

Irvine Ranch Water District supplies the city. Hardness runs from moderately hard to hard, depending on the season and where you live; the district publishes current figures 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 Irvine, 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. Unpermitted work can cause problems when you sell the house or file an insurance claim.

Plumbing questions from Irvine

How quickly can you get to a home in Irvine?

We give you an honest arrival window when you call, based on where our plumbers are that day. Burst pipes, sewage backups, and gas leaks are sent out first.

My Irvine home is not old. Why am I having plumbing problems?

Many villages date from the 1960s through the 1980s, so water heaters, angle stops, and supply lines from that era are near the end of their life. Hard-water scale speeds that up, in newer villages too.

Do plumbing jobs in Irvine need a permit?

Water heater replacements, sewer repairs, gas line work, and repipes generally do.

How does Irvine's water hardness affect my plumbing?

Mineral buildup scales water heaters and high-efficiency fixtures and can cause pinhole leaks in copper. Flush the water heater regularly, and consider a softener if you have older copper lines.

What customers say

★★★★★

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!
