How re-piping works in Santa Ana

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

Galvanized supply lines are common in Santa Ana homes built before 1970, especially in Floral Park, Downtown, and the West Side.

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.

What Santa Ana homeowners should know

One of the county's densest and oldest cities, with many homes built before 1970.

  • 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.

Re-piping questions in Santa Ana

What Santa Ana homeowners most often ask us about re-piping.

How long does repiping a Santa Ana 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

★★★★★

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.
