Zone-by-Zone Pressure Testing
We shut every zone and run them one at a time against a pressure testing gauge. A zone that will not hold pressure is flagged. This step alone rules out healthy zones and points us at the failing run within 20 minutes.

What Our Sprinkler Leak Detection Includes
Every visit covers zone-by-zone pressure testing, acoustic and thermal location, and a written summary of the failure. Repair parts and excavation are quoted after we locate the break, so you approve the number with the evidence in front of you.
Acoustic and Thermal Location
We walk the suspect run with an acoustic listening disc and a FLIR thermal camera, then confirm with a moisture meter and soil probe. Two independent readings before we mark the dig point keeps the excavation small.
Valve and Mainline Inspection
We open the valve box and inspect diaphragms, solenoids, and fittings. Cracked valve bodies and worn diaphragms are common in Santa Ana systems older than 15 years. We note every failed component in the summary.
Repair Quote Before Digging
Once we locate the break, you get a repair price before we open ground. That price covers the cut, the new PVC pipe and fittings, and the pressure test. No surprise line items after the fact.
Post-Repair Pressure Verification
We re-pressurize the repaired zone with a hydrostatic test kit and hold it to confirm zero drop. You watch the gauge with us. Then we reset your controller and walk the system to confirm even coverage.
Sprinkler System Leak Detection in santa ana
Sprinkler System Leak Detection in santa ana is a diagnostic plumbing service that pinpoints where an irrigation line, valve, or sprinkler head is losing water underground. We isolate each zone, pressurize the line with a hydrostatic test kit, and listen for the escape with an acoustic listening disc. A moisture meter and soil probe confirm the wet zone before we dig. Most residential systems take two to four hours to diagnose, and we mark the break with flags so you see exactly what we found.
Santa Ana irrigation systems run hard. Clay-heavy soil in Floral Park and French Park swells in winter and cracks in summer, shifting PVC pipe and stressing older brass valves. Add Santa Ana's inland heat, where July afternoons push past 95 degrees, and a small sprinkler line leak can waste 15 to 20 gallons a day before you ever notice a soggy patch. That is why lawn sprinkler leak detection Santa Ana homeowners call us for starts with the water meter, not a shovel.

Tools and Methods We Use
Tools & Equipment
Acoustic listening disc
Amplifies the sound of escaping water underground so we can pinpoint a sprinkler line break from the surface without digging.
FLIR thermal imaging infrared camera
Shows the temperature contrast between wet and dry soil, tracing the path of a leaking irrigation line across a lawn.
Pressure testing gauge
Confirms which zone is losing pressure and verifies the repair holds after we finish. Our first and last check on every job.
Moisture meter and soil probe
Reads soil moisture at depth to confirm the wet band before we open ground, and to check that the ground dries after repair.
Pipe and line locator
Traces buried irrigation runs and marks the dig point, keeping excavation small and away from hardscape edges.
Pipeline inspection camera
Lets us look inside a line to confirm a crack, root intrusion, or collapse before we commit to a repair method.
Hydrostatic test kit
Pressurizes a repaired zone and holds it to prove zero drop. The final sign-off on every sprinkler repair we complete.
Methods & Standards
Zone isolation testing
We run one zone at a time against a pressure gauge. A zone that will not hold pressure is the failing run. This method narrows a six-zone system to a single suspect in under 20 minutes and rules out healthy zones.
Acoustic and thermal cross-check
We never dig on one reading. An acoustic hit is confirmed with a thermal image and a moisture reading. When all three agree, the dig point is accurate to within a couple of feet, which keeps the excavation small.
Non-invasive first
We exhaust acoustic, thermal, tracer gas, and moisture mapping before opening ground. Most Santa Ana sprinkler repairs need one small hole, not a trench, and that saves sod, irrigation tubing, and labor.
Code-correct repair
Repairs follow California Plumbing Code and Uniform Plumbing Code standards, with IAPMO-certified fittings and materials matched to the existing pipe. We use PVC cement, pipe repair clamps, and SharkBite couplings where the application allows.
When to Call for Sprinkler Leak Detection
01
You got a water bill that jumped $60 or more and the irrigation controller has been running the same schedule for months.
What we do: We start at the meter, isolate the irrigation shut-off, and test each zone with a pressure gauge. If the loss is on the irrigation side, we locate it acoustically and repair the same visit.
→ You get the leak stopped and a clear answer on what caused the spike, usually within a single appointment.
02
A zone will not hold pressure and the controller throws a fault every time it runs.
What we do: We open the valve box, test the solenoid and diaphragm, and pressure-test the zone. If the valve is fine, we trace the mainline with a pipeline inspection camera and acoustic gear to find the break.
→ The zone runs clean again, and the controller stops faulting. You get the failed part in hand so you can see what gave out.
03
You see a wet patch in the lawn that never dries, even days after the sprinklers run.
What we do: We confirm the wet band with a soil probe and thermal camera, locate the pipe beneath it, and repair the break. If the wet patch is near a cleanout, we also run a drain camera to rule out a sewer issue.
→ The ground dries out, the turf recovers, and you avoid repairing the wrong pipe.
04
A mainline shears after a root shift or a contractor digs near the parkway.
What we do: We respond same-day, shut the zone at the valve, and rebuild the line with new PVC pipe, fittings, and PVC cement. Then we pressure-test and backfill.
→ Water stops running down the gutter, and the system is back online without a second trip.
How Sprinkler Leak Detection Runs in santa ana
Santa Ana sits inland enough that summer afternoons hit 95 degrees and winter nights drop near 40, and that swing works on irrigation pipe. PVC expands and contracts, joints loosen, and older brass valves crack at the bonnet. The clay soil in neighborhoods like Floral Park and French Park swells when wet and shrinks when dry, shifting lines and stressing fittings year after year. We also see plenty of mixed-material systems, where copper pipe meets CPVC pipe at an adapter that has been weeping for a decade. When you call for sprinkler system leak detection near me Santa Ana CA, we bring the acoustic disc, the thermal camera, and a soil probe, and we test the whole system rather than the one zone you noticed. If your sprinkler system is losing pressure Santa Ana California, the cause is usually a failed valve diaphragm or a cracked mainline fitting, and both show up fast under a pressure gauge. We work to City of Santa Ana building permits where excavation touches public parkway, and we follow Orange County Water District regulations on any connection we alter.
Neighborhoods We Serve
-
Floral Park
Historic lots with mature roots that shift irrigation lines. We trace runs carefully here to avoid cutting root systems that hold the soil.
-
South Coast Metro
Commercial landscapes with larger zones and higher pressure. Mainline failures here waste water fast, so we prioritize pressure testing.
-
Washington Square
Older residential tracts where brass valves and copper supply stubs are common. Diaphragm failures show up often.
-
Cornerstone Village
Newer builds with deeper mainlines and drip zones. We use line locators to trace runs before any excavation near hardscape.
Local Conditions We Plan For
-
Clay soil that swells and shrinks seasonally
Movement stresses pipe joints and fittings, which is why we see more cracked PVC couplings here than in sandy-soil cities.
-
Inland heat pushing past 95 degrees in summer
Higher irrigation demand means leaks waste more water and show up faster on the meter, but also dry the surface soil and hide the wet band.
-
Mixed copper and plastic irrigation runs
Adapters between copper pipe and CPVC or PVC pipe are frequent failure points, so we test each material transition separately.
-
Mature tree roots in older neighborhoods
Roots intrude and crush irrigation lines, so we use a pipeline inspection camera to confirm the cause before repairing.

Sprinkler Problems We Solve in Santa Ana
Most irrigation calls come down to one of a handful of failures. We have seen them all across Santa Ana, and we know which ones hide underground and which ones show at the valve box.
Problem
Water bill climbing with no visible puddle
An underground sprinkler line leak can waste 15 to 20 gallons a day, adding $40 to $90 to a bi-monthly bill and slowly starving the turf above it.
Our Fix
We isolate each zone against a pressure gauge, then listen for the escape with an acoustic disc. A pinhole leak in PVC pipe shows up fast once the zone is pressurized, and we repair the section with new pipe and fittings.
Problem
One zone stays soggy while the rest look dry
A failed valve diaphragm keeps that zone weeping 24/7, drowning roots and softening the soil under walkways until concrete cracks.
Our Fix
We open the valve box, test each diaphragm, and replace the failed one. If the valve body is cracked, we swap the whole valve and re-test the zone. This is the most common sprinkler valve leak detection Santa Ana CA repair we make.
Problem
Brown stripes and dead patches across the lawn
A broken sprinkler head or crushed drip tubing starves part of the zone, and the grass dies in bands that match the pipe run.
Our Fix
We map the zone with a moisture meter, find the crushed or clogged section, and rebuild it with new irrigation drip tubing and heads. Then we rebalance the controller run times so coverage is even.
Problem
Soggy ground near the sidewalk or driveway edge
Water migrating under hardscape softens the base, and a cracked driveway or lifted walkway costs far more than the plumbing repair.
Our Fix
We use a pipe and line locator to trace the run before it reaches the slab edge, then repair the break with pipe repair clamps or a cut-and-couple. Catching it early keeps the concrete intact.
Why Santa Ana Homeowners Call Us First
A hidden sprinkler leak wastes water, kills turf, and can undermine a driveway or walkway. Finding it fast protects your landscape and your water bill.
-
Stop the Water Waste
A pinhole leak in a half-inch irrigation line can bleed 15 to 20 gallons a day. Over a 90-day billing cycle that is thousands of gallons and a noticeably higher bill. We locate the loss, cap it, and verify the meter stops spinning before we pack up.
-
Save the Turf
Brown stripes and mushy patches usually mean the zone is starving or drowning. Our sprinkler system leak locating Santa Ana California service maps the wet soil with a moisture meter so we repair the right spot, not the whole yard, and your grass recovers in weeks.
-
Protect Hardscape
Water under a driveway or walkway softens the base and cracks concrete. We use a pipeline inspection camera and pipe and line locator to trace the run before it undermines slab edges, saving you a concrete pour on top of a plumbing repair.
-
One Visit, One Fix
We diagnose and repair in the same appointment whenever parts allow. That means a broken sprinkler line detection Santa Ana CA call on Tuesday morning is a working, pressure-tested system by Tuesday afternoon, not a second trip and a second service fee.

Found a sprinkler leak two other companies missed. They used a thermal camera and a listening device, marked the spot, and dug one small hole. Repaired it the same day. Pressure test held. Fair price and no mess left behind.
Yelp ★★★★★4.8
Our water bill was up $90 and we could not figure out why. Planet Plumbing isolated the zones, found a cracked valve, and replaced it in about an hour. They showed us the old part and reset the controller. Honest work.
BBB ★★★★★4.9
Called at 6 a.m. with water running down the parkway from a broken mainline. Tech arrived before noon, shut the zone, and rebuilt the line. Cleaned up the dirt and tested it twice. Exactly what you want from a plumber.

Frequently Asked Questions
Real answers to the questions we hear most often from local homeowners and property managers.
How much does sprinkler system leak detection cost in Santa Ana CA?
Most residential sprinkler leak detection in Santa Ana runs $180 to $450 in 2026, depending on how many zones we test and how deep the line sits. Repair is quoted separately once we see the break. A single valve diaphragm swap sits at the low end; a mainline cut under a driveway sits higher. We give you the number before we start.
How do I find a leak in my sprinkler system?
Start at the water meter. Turn off every fixture in the house, then watch the leak indicator on the meter with the irrigation controller off. If it still spins, you have a supply-side leak. If it stops, run one zone at a time and watch for a pressure drop. That points to the zone. From there you need an acoustic listening disc to hear the break underground.
Can I turn off one zone to find a sprinkler leak?
Yes, and that is exactly how we start. Shut every zone at the controller, then open one at a time and watch the pressure testing gauge. A zone that will not hold pressure is your suspect. If the meter still moves with all zones off, the leak is on the mainline between the backflow device and the valve box.
Does sprinkler leak detection include repair in California?
Detection and repair are separate line items, but we do both on the same visit whenever parts are on the truck. California C-36 licensed work covers the irrigation mainline and valves; drip tubing and head replacement are straightforward add-ons. You approve the repair price after we show you the located break, never before.
