How leak detection works in Santa Ana

We find leaks in slabs, walls, and supply lines in Santa Ana with acoustic and electronic equipment, so nothing is opened on a guess.

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 leak detection

Call when the water bill rises with no change in use, you hear running water with every fixture off, a floor or wall feels warm or damp, mold appears where it should be dry, the meter keeps moving with the water shut off, or flooring turns soft or discolored.

  1. We diagnose first

    We find the actual cause before recommending any repair.

  2. We quote upfront

    You get a clear price before any work starts.

  3. We fix it right

    The repair is completed and tested before we leave.

  4. We follow up

    If something is not right afterward, call us and we come back.

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.

Leak Detection questions in Santa Ana

What Santa Ana homeowners most often ask us about leak detection.

How do I know if I have a slab leak in my Santa Ana home?

Look for warm spots on the floor, the sound of running water when everything is off, a sudden jump in the water bill, and new cracks in floors or walls near the foundation.

Can you find a leak without cutting into my walls?

Usually, yes. Acoustic and thermal equipment locates the leak from the surface, and the structure is opened only at the confirmed spot.

How long does leak detection take in Santa Ana?

Most house calls take one to two hours. Scanning a slab can take a little longer. You get a clear location and diagnosis before any repair starts.

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.
