How re-piping works in Irvine

Corroded or failing supply lines cannot be patched forever. We replace aging galvanized and polybutylene pipe in Irvine homes with copper or PEX.

Nearly every Irvine home sits on a slab, and copper in the 1970s and 1980s villages is now at the age when pinhole and slab leaks appear.

When to call for re-piping

Consider a repipe when water pressure keeps dropping, the hot water looks rusty or smells metallic, leaks have appeared in different places within a few years, a plumber has found heavy corrosion inside the pipes, or the house has polybutylene pipe that has already failed once.

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.

Re-piping questions in Irvine

What Irvine homeowners most often ask us about re-piping.

How long does repiping a Irvine home take?

Most single-family homes take about two to five days, depending on size and layout. Water service is kept on wherever possible.

Copper or PEX: which is better?

Both are durable and approved by code. Copper has the longer track record and handles heat and sunlight well. PEX is flexible, routes through walls with less drywall work, and resists freeze damage. The right choice depends on the layout of your home and your priorities.

Will repiping mean opening my walls?

Yes, because supply lines run through walls and ceilings. We keep the number and size of openings down and can coordinate the drywall repair.

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!
