What our Underground Leak Detection includes

Every detection visit includes the full diagnostic workup, a marked leak point, and a written summary of what we found. Repair is quoted separately so you can decide how to proceed. Here's what's covered.

Full system isolation test

We shut every fixture and valve, then monitor the pressure testing gauge and water meter to confirm whether the leak is on the supply side, drainage side, or irrigation loop. This 15-minute step prevents us from chasing the wrong pipe.

Acoustic and thermal scan

We walk the buried line with an acoustic listening disc and a FLIR thermal imaging infrared camera, marking anomalies every 3 feet. A moisture meter and soil probe confirm the wet zone. This is the core of the detection service.

Leak point marking

We paint the confirmed leak location within 12 to 18 inches and show you the mark before any excavation. You see exactly where we'll open the ground or slab, and why.

Written findings summary

You get a one-page summary with the leak location, pipe material, probable cause, and recommended repair. It's useful for insurance claims, HOA records, and future plumbing work on the property.

Repair quote on the spot

Once we've located the leak, we quote the repair before we leave. The quote covers access, pipe material, fittings, and restoration. If you approve, we schedule the repair, often for the same day.

Post-repair pressure test

When we do the repair, we hydrostatic-test the line at 80 PSI for 30 minutes before backfilling. You get a pass/fail result and a 2-year workmanship warranty on the repair.

Underground Leak Detection in santa ana, explained


Underground Leak Detection in santa ana is the process of finding water or gas escaping from buried pipes without excavating the whole yard. We pressurize the line, then walk it with an acoustic listening disc and an ultrasonic leak detector to hear the hiss. A thermal imaging infrared camera confirms the wet zone. Once we mark the spot, we open a small access hole, repair the pipe, and hydrostatic-test it before backfill.

Santa Ana homes sit on a mix of older copper pipe and newer PEX tubing, and both fail differently. Copper corrodes from the inside out and pinholes at 40 to 60 PSI; PEX fittings can weep at the crimp ring. Add Orange County's clay-heavy soil, which shifts with every wet winter, and buried lines take a beating. If your yard is always wet Santa Ana CA, or your meter spins with every fixture off, that's your cue to call.

How our leak detection process works

Five steps, one visit in most cases. Here's exactly what happens from the moment you call until the line is back in service.

01

Schedule

Call or book online — a real human picks up and confirms a 2-hour arrival window.

02

Diagnose

Licensed tech inspects on-site, then walks you through the cause and your options.

03

Fix

The job is completed to code and done right the first time — no shortcuts, no surprises.

04

Guarantee

Every job backed by a written workmanship warranty — and we stand behind it.

Tools and methods we use

Tools & Equipment

Acoustic listening disc

Picks up the frequency of pressurized water escaping a buried pipe. We walk the line in 3-foot increments and mark the loudest point.

FLIR thermal imaging infrared camera

Reads temperature differences caused by escaping water. Works through concrete, tile, and up to 3 feet of soil.

Ultrasonic leak detector

Catches high-frequency signals that acoustic gear misses, especially on plastic pipe and low-pressure irrigation lines.

Electronic leak detection wand

Confirms moisture presence in soil and behind walls. We use it alongside the soil probe to map how far water has traveled.

Pressure testing gauge and hydrostatic test kit

Isolates the leak to a specific line and verifies the repair at 80 PSI for 30 minutes before backfill.

Pipeline inspection camera and drain camera

Rules out sewer and drainage issues before we open a slab. Also used to inspect the inside of the pipe after repair.

Tracer gas detector

Confirms gas line leaks and hard-to-hear water leaks by introducing a safe tracer gas and reading its escape point.

Methods & Standards

Isolation and pressure testing

We shut every fixture and valve, then monitor the pressure gauge and water meter. If the meter moves, the leak is on the supply side. This method eliminates 80% of the guesswork before we bring out the acoustic gear.

Acoustic correlation

Two sensors placed on the pipe measure the time difference of the leak sound. The correlation math gives us a distance-to-leak reading accurate to within 12 inches on most metallic lines.

Thermal imaging survey

We scan the floor, slab, and yard with a FLIR camera and look for temperature anomalies. Wet soil and escaping water change the thermal signature, which shows up clearly on the screen.

Tracer gas testing

For gas lines and stubborn water leaks, we introduce a safe tracer gas into the isolated line and read its escape point with a detector. It's the most reliable method for lines under concrete or deep soil.

Hydrostatic testing after repair

Every repair we make gets pressure-tested at 80 PSI for 30 minutes. If it holds, we backfill. If it drops, we re-open and fix it before you see a bill.

When to call for Underground Leak Detection

01

Your water bill jumped 40% and you can't find a leak inside the house.

What we do: We run the isolation test, confirm the meter is spinning, and scan the buried service line with acoustic and thermal gear. Most supply-side leaks are located in under 90 minutes.

→ You get a marked leak point and a repair quote the same day, and your next water bill drops back to normal.

02

There's a wet patch in the yard that stays soggy weeks after the last rain.

What we do: We pressure-test the irrigation loop separately from the domestic line, then use an electronic leak detection wand and soil probe to find the break. If it's the main line, we trace it with a pipe and line locator.

→ The failed section gets repaired, the grade is restored, and your landscaping stops drowning.

03

You're buying a santa ana home and the seller's disclosure mentions a prior slab leak.

What we do: We perform a full underground leak detection scan on the supply, drainage, and irrigation lines, plus a hydrostatic test on the repaired section. You get a written report on the current condition.

→ You know exactly what you're buying, and you have documentation for your lender and insurance.

04

A pool is losing an inch of water a day and the deck feels soft.

What we do: We isolate the pool plumbing from the domestic system, pressure-test the pool loop, and locate the break with acoustic gear. We repair the failed section without draining the pool.

→ The pool holds water again, the deck dries out, and you avoid a full pool re-plumb.

05

You smell gas near the meter or along the side yard.

What we do: We shut the meter, run a tracer gas detector along the buried line, and coordinate with the utility before any repair. Safety protocol comes first, then we locate and quote the fix.

→ The leak is isolated, the utility is satisfied, and the line is repaired to code with a pressure test on record.

How Underground Leak Detection runs in santa ana

Santa Ana sits on a mix of post-war tract homes, 1920s bungalows, and newer infill construction, which means we see every pipe material and every failure mode. The older neighborhoods like French Park and Wilshire Square still have original copper service lines that pinhole from the inside. Newer builds in Sandpointe and Cornerstone Village use PEX and CPVC, where the failure is usually a fitting or a crimp ring. Orange County's clay soil expands and contracts with the wet and dry seasons, and that movement stresses buried lines year after year. Our current season is fall, so we're heading into the Santa Ana winds and the first rain, which is when soil shifts and old leaks surface. If you've been putting off that wet spot, now is the time. We handle City of Santa Ana building permits when the repair touches the main, and we follow California Plumbing Code and Orange County Water District regulations on every job. Whether you need buried pipe leak detection Santa Ana or a full repair, we keep the excavation small and the documentation clean.

Neighborhoods We Serve

  • Floral Park

    Historic homes with original copper service lines and mature root systems. We use acoustic correlation to avoid trenching the landscaping.

  • South Coast Metro

    Commercial and mixed-use properties with larger meters and longer service lines. We schedule after-hours detection to avoid business disruption.

  • Washington Square

    1920s bungalows on raised foundations. Slab and crawlspace leaks are common, and thermal imaging works well here.

  • Sandpointe

    Newer PEX and CPVC systems. Failures tend to be at fittings and manifolds rather than mid-pipe, so we pressure-test zones individually.

  • Artesia Pilar

    Larger lots with extensive irrigation. We isolate the sprinkler loop from the domestic line before scanning to avoid false positives.

Local Conditions We Plan For

  • Clay-heavy soil that shifts with wet and dry seasons

    Movement stresses buried copper and PVC, causing pinholes and joint failures. We factor soil type into where we expect the leak to be.

  • Older homes with original copper service lines

    Copper corrodes from the inside out. We see pinholes at 40 to 60 PSI, often in the yard rather than under the slab.

  • Fall Santa Ana winds and first rain

    Soil moisture changes rapidly, which can open a leak that was marginal all summer. We see a spike in calls from October through December.

  • High water table in low-lying areas

    A leak can stay hidden longer because the soil is already wet. We rely more on pressure testing and tracer gas in those zones.

Pinhole leak in Floral Park copper line

Before

A homeowner's water bill went from $85 to $340 in one cycle. The yard had a soggy patch near the sidewalk, and the meter spun with every fixture off. Two other plumbers recommended trenching the entire front lawn.

After

We located the pinhole within 14 inches using acoustic correlation, opened a single 12-inch access hole, and replaced 18 inches of copper. The hydrostatic test held at 80 PSI for 30 minutes. Water bill returned to $88 the next cycle.

Maintenance: We recommended a full-line pressure test every two years and a water softener to slow copper corrosion. Both are inexpensive compared to another repair.

Before

A property manager had a persistent wet spot in the parking lot that three landscapers couldn't fix. The asphalt was starting to crack, and the water bill for the building was up 22%.

After

We isolated the irrigation loop, found the break with an electronic leak detection wand, and repaired the lateral in two hours. The asphalt patch was 2 square feet instead of the 40-foot trench another contractor quoted.

Maintenance: We set the irrigation controller to a seasonal schedule and marked the zone valve for future reference. The property manager now checks the meter monthly.

Before

A homeowner noticed hot spots on the bathroom floor and a crack running along the baseboard. The water bill was up 30%, and a flooring contractor had already quoted $4,000 to replace the tile.

After

Thermal imaging and acoustic correlation pinpointed the leak under the slab. We opened a 16-inch access point, repaired the copper line, and pressure-tested it. The flooring repair was limited to one tile, not the whole bathroom.

Maintenance: We documented the repair location on a site sketch and recommended an annual meter check. The homeowner now has a baseline for future monitoring.

Problems our Underground Leak Detection solves

Most underground leaks announce themselves through the water bill, a wet spot, or a spinning meter. Here are the four we see most often in santa ana, and how we handle each one.

Problem

Water bill doubled with no visible leak

A buried pinhole leak can waste 10,000 gallons a month and cost you $200 to $400 per billing cycle. Left alone, it undermines soil and can shift a foundation.

Our Fix

We isolate the system, confirm the meter is spinning with all fixtures off, then use acoustic and thermal tools to trace the loss to the buried line. Most leaks are marked and repaired within a single visit.

Problem

Soggy yard that never dries out

Constant moisture kills landscaping, attracts pests, and signals a failing irrigation or service line. It can also saturate the soil under your foundation.

Our Fix

We separate the irrigation loop from the domestic line with a pressure test, then locate the break with an electronic leak detection wand and soil probe. We repair the failed section and restore the grade.

Problem

Hot spots on the floor or foundation cracks

A slab leak under the foundation warps flooring, cracks tile, and grows mold within weeks. The longer it runs, the more expensive the repair becomes.

Our Fix

Thermal imaging and acoustic correlation pinpoint the leak under the slab. We open a small access point, repair the pipe, and pressure-test it. Most slab repairs are completed in one day.

Problem

Meter spinning with everything shut off

That's a supply-side leak, and it's costing you money every hour. It can also drop your water pressure and introduce contaminants if the line loses pressure.

Our Fix

We verify the meter test, then trace the main and service lines with a pipe and line locator. Once we mark the break, we repair it with code-approved fittings and hydrostatic-test the line before backfill.

Why homeowners call us first

A hidden leak can waste 2,000 to 10,000 gallons a month and undermine a foundation before you see a drop indoors. Here's what you get when we handle it.

  • No guesswork, no random digging

    We mark the leak within 12 to 18 inches before any shovel hits dirt. That means one small access hole instead of a trench across your lawn. Most residential jobs in santa ana are located and repaired in a single visit, and you keep your landscaping intact.

  • Lower water bills fast

    A pinhole leak in a copper service line can push a Santa Ana household from 6 units to 20 units a month. Once we isolate and repair the line, usage drops back to normal on the next cycle. We show you the before-and-after meter reading so you can verify it yourself.

  • Protects your foundation

    Water migrating under a slab causes foundation cracks, hot spots on the floor, and mold growth within weeks. Underground leak locating near Santa Ana catches the problem while it's still a pipe issue, not a structural one. That's the difference between a $600 repair and a $15,000 foundation job.

  • Licensed, insured, code-correct

    We hold a California C-36 Plumbing Contractor License and pull City of Santa Ana building permits when the scope requires one. Every repair meets California Plumbing Code and Uniform Plumbing Code standards, and we use IAPMO-certified fittings. You get a written warranty on the repair, not just a handshake.

Licensed, certified, and reviewed

Verified Reviews

Google ★★★★★4.9

Found a slab leak under our bathroom in about an hour. They marked the spot, showed us the thermal image, and repaired the copper line the same day. The flooring damage was one tile, not the whole room. Fair price and clean work.

Yelp ★★★★★4.8

Our water bill was triple normal and we had no idea why. Planet Plumbing isolated the system, found the leak in the front yard, and fixed it before the weekend. They credited the detection fee toward the repair, which I appreciated.

BBB ★★★★★4.9

Called at 10 p.m. with water pooling near the meter. They had a tech out within two hours, shut off the main, and came back first thing to repair the line. No emergency markup, no runaround. Highly recommend for underground leaks.

Google ★★★★★5.0

We manage several rental properties in Santa Ana and use Planet Plumbing for all our leak detection. They're consistent, they document everything, and they don't recommend excavation unless it's necessary. That saves us thousands every year.

Local leak detection experience

Our technicians train on RIDGID locators, Sewerin acoustic gear, and Gutermann correlation equipment, and we recertify on ASSE standards every cycle. We've worked the older galvanized and copper systems in French Park and the newer Uponor and Viega PEX installs in Sandpointe. That range matters: a leak in 1950s copper sounds different than a weeping SharkBite fitting, and the repair method changes with it. We carry a California C-36 Plumbing Contractor License, OSHA safety compliance training, and backflow tester certification for the jobs that touch the main. Every tech on the truck can read a pressure gauge, run a thermal scan, and explain what they found in plain English.

  • ASSE 6050 and 6070 cross-training on leak detection and pipe condition assessment
  • Certified backflow tester for water main and service line work
  • Trained on RIDGID, Fluke, Milwaukee Tool, and FLIR diagnostic platforms
  • Experienced with copper, PEX, CPVC, PVC, and ABS pipe systems
  • OSHA-compliant confined space and trench safety for buried line repairs

Frequently Asked Questions

Real answers to the questions we hear most often from local homeowners and property managers.

How do you find an underground water leak in Santa Ana CA?
We isolate the system, then use an acoustic listening disc and ultrasonic detector to hear the leak, and a FLIR thermal camera to confirm the wet zone. A pressure gauge and water meter tell us whether it's supply-side or drainage. Most leaks are marked within 12 to 18 inches in under 90 minutes.
How much does underground leak detection cost?
Typical 2026 pricing in Santa Ana runs $250 to $550 for detection, depending on line length and whether it's under slab, yard, or driveway. Repair is quoted separately, usually $400 to $1,800. We give you both numbers upfront, and the detection fee is credited toward the repair if you hire us.
Can you detect a leak under concrete or grass?
Yes. Acoustic and thermal tools read through 4 to 6 inches of concrete and up to 3 feet of soil. We use a pipeline inspection camera or tracer gas detector when the signal is ambiguous. We only open the slab or turf at the confirmed leak point, not across the whole run.
Does underground leak detection include repair?
Detection and repair are separate line items, but we do both. You approve the detection fee first, then the repair quote once we've located the break. If you want underground leak detection and repair Santa Ana California handled in one visit, we schedule the repair immediately after the locate.
