What is included
What Is Included in Our Sprinkler Leak Detection Service
Every detection visit includes a full zone-by-zone pressure test, acoustic scan, and thermal imaging survey. Repair work is quoted separately once we know the pipe material and depth. Here is what you get on the detection side.
Full Zone Pressure Test
We isolate and pressurize every irrigation zone with calibrated gauges. A zone that will not hold pressure is flagged for further scanning. This step takes 20 to 30 minutes and covers up to 8 zones.
Acoustic Listening Survey
We walk the yard with acoustic listening devices to hear water escaping under pressure. The microphone can detect a leak through 4 inches of soil and 2 inches of asphalt. We mark any hot spots with paint.
Thermal Imaging Scan
A FLIR thermal imaging camera shows temperature differences caused by saturated soil. We scan the entire irrigated area and compare it to dry ground. This method works day or night and through most ground covers.
Tracer Gas Confirmation
For leaks that acoustic tools cannot isolate, we inject a harmless tracer gas and sniff for it with a Sewerin detector. This confirms the exact spot before we dig. It is the same method used for gas line leaks.
Written Findings and Marking
You get a written summary of which zone failed, where the leak is, and what repair is needed. We mark the spot with biodegradable paint and walk you through the findings before we leave. No surprises.

Service overview
What Sprinkler System Leak Detection Nashua NH Really Involves
Sprinkler system leak detection Nashua NH is the process of finding water loss in an irrigation system before it destroys your lawn or spikes your water bill. We pressurize each zone, then listen for the distinct hiss of escaping water with acoustic listening devices. Thermal imaging cameras show temperature differences where saturated soil hides a break. Pressure testing gauges confirm which zone is losing pressure, and pipe inspection cameras let us see inside PVC pipe and PEX tubing without digging up the whole yard.
Nashua's freeze-thaw cycles crack fittings and split underground lines every winter. By the time you notice a soggy patch near Mine Falls or a $300 water bill in Hillsborough County, the leak has often been running for weeks. We handle lawn sprinkler leak detection Nashua for homeowners who want to know exactly where the problem is before anyone picks up a shovel. If you have been searching for sprinkler system leak detection near me Nashua NH, we cover every neighborhood from Crown Hill to Nashua Highlands.
- Stop Water Waste Fast — A single 1/8-inch underground sprinkler leak can waste over 3,000 gallons per month. We locate and isolate it the same day, so your meter stops spinning and your next bill drops back to normal. Most repairs are completed within two to four hours of arrival.
- No Guesswork Digging — We mark the exact leak location with paint before any excavation. That means one small hole instead of trenching your entire lawn. Our electronic leak detection equipment narrows the break to within a few inches, even under driveways or mature landscaping.
- Protect Your Landscape — Saturated soil drowns roots and invites fungus. By catching the leak early, we save the shrubs and turf you have invested in. We also check for slab leaks and foundation leaks nearby, since irrigation breaks often push water toward your home's base.
- Licensed, Insured, Warrantied — Every technician works under our NH Master Plumber License and carries OSHA Safety Certification. We back sprinkler leak repair Nashua work with a written warranty on parts and labor. You get a fixed price before we start, not a surprise invoice after.

Emergency sprinkler leak detection Nashua New Hampshire calls get priority, especially when a break is flooding a foundation or washing out a driveway. We carry the parts to repair most common breaks on the first visit.
- Non-Invasive First — We exhaust every non-invasive method before we dig. Acoustic listening, thermal imaging, and tracer gas detection solve 9 out of 10 jobs without a shovel touching your yard. That saves your landscaping and cuts the repair bill.
- Upfront Flat Pricing — You get a written price before we start. No hourly meter running while we search. Affordable sprinkler leak detection Nashua pricing means you know the number when you book, and it does not change unless you approve additional work.

The service timeline
How Our Sprinkler Leak Detection Process Works
Call and Schedule
You call 603 571 4078 or book online. We ask a few questions about your system, your water bill, and where you have seen soggy spots. Most Nashua appointments are scheduled the same day or next morning. You get a two-hour arrival window and a text when the technician is on the way.
Zone-by-Zone Pressure Test
We isolate each irrigation zone and pressurize it with pressure testing gauges. A zone that will not hold pressure gets flagged immediately. This step takes 20 to 30 minutes and tells us whether the leak is in the mainline, a lateral line, or a valve box.
Acoustic and Thermal Scan
Next we walk the yard with acoustic listening devices and a FLIR thermal imaging camera. The microphone picks up the sound of water escaping under pressure. The camera shows the temperature signature of saturated soil. Together they pinpoint the break within inches, even under 4 inches of sod.
Mark and Confirm
We mark the spot with biodegradable paint and confirm the diagnosis with a second method, usually a Sewerin tracer gas detector or a RIDGID pipe inspection camera. You see the evidence on screen before we dig. No guesswork, no exploratory trenching.
Repair and Re-Test
We excavate a small access hole, cut out the damaged section of PVC pipe or PEX tubing, and install a new fitting with pipe sealant and plumber's tape. Then we re-pressurize the zone and watch the gauge for 15 minutes. If it holds, we backfill, compact, and restore the sod.

Tools and Methods We Use for Sprinkler Leak Detection
Acoustic Listening Devices
Amplifies the sound of water escaping under pressure. We use it to hear leaks through soil, sod, and asphalt. It is the fastest way to scan a large yard.
FLIR Thermal Imaging Cameras
Shows temperature differences caused by saturated soil. We scan the irrigated area and compare it to dry ground. Works day or night.
Sewerin Tracer Gas Detectors
Sniffs for a harmless tracer gas injected into the irrigation line. Pinpoints leaks that acoustic tools miss, especially in clay soil.
Pressure Testing Gauges
Calibrated gauges that isolate each zone and measure pressure loss. Tells us whether the leak is in the mainline or a lateral line.
RIDGID Pipe Inspection Cameras
Lets us see inside PVC pipe and PEX tubing without digging. We confirm cracks, root intrusion, and broken fittings before excavation.
Moisture Meters
Measures water content in soil and building materials. We use it to check for foundation leaks and slab leaks near the irrigation break.
Milwaukee and DeWalt Cordless Tools
Our trucks carry Milwaukee and DeWalt cordless tools for fast excavation and repair. We can cut, fit, and test a new pipe section in under an hour.
Zone Isolation Pressure Testing
We close all zone valves and pressurize one zone at a time. A zone that loses pressure has a leak. This method narrows the search area from the whole yard to a single line in about 20 minutes.
Acoustic Correlation
We place two acoustic sensors on the ground and compare the sound arrival times. The leak is where the sounds match. This method locates leaks within 6 inches, even under 4 inches of sod.
Thermal Imaging Survey
We walk the irrigated area with a FLIR camera and look for temperature anomalies. Saturated soil is cooler than dry soil in summer and warmer in winter. The camera shows the leak plume clearly.
Tracer Gas Injection
We inject a harmless gas into the isolated line and sniff the surface with a Sewerin detector. The gas escapes at the leak point. This method works when acoustic tools are confused by background noise.
Backflow Prevention Testing
We test the backflow assembly after every repair to confirm it still meets EPA WaterSense and New Hampshire code. A failed backflow device can contaminate your irrigation water.

Local execution
How Sprinkler Leak Detection Runs in Nashua
Nashua's climate is hard on irrigation systems. We get freeze-thaw cycles from November through March, and the ground shifts enough to crack fittings and split PVC pipe. Most of the leaks we find in Hillsborough County happen at the zone valve manifold or where a lateral line passes under a driveway. Clay soil holds water, so a small break can turn into a large sinkhole in one season. We also see older polybutylene lines in French Hill and Crown Hill that become brittle after 30 years. If you need affordable sprinkler leak detection Nashua, we know where to look first. We also handle sprinkler system leak detection South Nashua NH, where newer systems often have issues with high water pressure at the mainline connection.
French Hill
Many homes here have original 1980s irrigation systems with polybutylene lines that crack at the fittings. We carry replacement PEX tubing on every truck.
Nashua Highlands
Newer systems with smart controllers often have high static pressure. We check the pressure regulator at the mainline before testing zones.
Mine Falls
The soil near the river is sandy and drains fast, so leaks do not always show as soggy spots. We rely on acoustic tools here more than thermal imaging.
Exit 8 Neighborhood
Driveway crossings are common. We use tracer gas detection to find leaks under concrete without breaking the slab.
Winter freeze-thaw cycles from November to March
Water left in the lines expands and cracks fittings. We recommend blowing out the system every fall. If you skip it, we find the break in spring.
Clay soil in central Nashua
Clay holds water and hides the leak plume. Thermal imaging is less effective, so we rely on acoustic listening and tracer gas.
High water pressure in newer developments
Pressure above 80 PSI stresses fittings and valves. We install a pressure regulator at the mainline to prevent future leaks.
Older galvanized and polybutylene lines
These materials corrode from the inside. We replace the damaged section with PEX tubing or copper pipe, which lasts longer.
Before and after
What a successful service visit changes.
Hidden Lateral Line Under Front Lawn
Before
A Crown Hill homeowner had a water bill that jumped from $85 to $340 in one month. The lawn had a soggy strip but no visible geyser. Two other companies guessed and quoted full lawn replacement.
After
We pressure tested all six zones and found zone 3 losing 12 PSI in 10 minutes. Acoustic tools marked the break within 8 inches. We excavated one 14-inch hole, replaced 2 feet of PVC pipe, and re-tested. The bill returned to $88 the next cycle.
Maintenance: We recommended blowing out the system every November and checking the zone valve manifold each spring. The repair has held for two seasons.
Driveway Crossing Leak in South Nashua
Before
A South End homeowner had water bubbling up through the driveway seams. The irrigation line ran under 12 feet of concrete. A competitor said the only fix was to jackhammer the entire driveway.
After
We used tracer gas detection to pinpoint the leak within 4 inches of the driveway edge. We excavated from the side, sleeved the damaged section with PEX tubing, and pulled it through. The driveway stayed intact. Repair cost $680 instead of $4,500.
Maintenance: We installed a pressure regulator to keep the zone under 65 PSI and advised the homeowner to watch for new wet spots after spring startup.
Foundation Saturation from Irrigation Break
Before
A Nashua Highlands homeowner noticed dampness in the basement after running the sprinklers. A foundation company quoted $8,000 for waterproofing. The real problem was an irrigation break 3 feet from the foundation.
After
We scanned the area with thermal imaging and found the leak plume. The break was in a lateral line that had cracked at a fitting. We repaired it in 90 minutes. The basement dried out within a week, and the waterproofing was unnecessary.
Maintenance: We checked the foundation for cracks and found none. The homeowner now runs each zone for 10 minutes monthly to watch for pressure loss.
Problems we solve
Sprinkler Problems We Solve for Nashua Homeowners
Most irrigation leaks announce themselves with a high water bill, a soggy patch, or a zone that will not hold pressure. Here are the specific problems we fix every week in Nashua.
Water bill doubled with no obvious leak
A hidden underground break can waste 3,000 gallons per month. You pay for water that never reaches your grass, and the saturated soil kills roots. We pressure test each zone and use acoustic listening devices to find the break. Most leaks are located within 45 minutes. We mark the spot, repair the pipe, and re-test the zone before we leave.
Soggy patch in the lawn that never dries
Constant moisture drowns turf roots and invites fungus. It also softens the ground, making it unsafe for kids and pets. Ignoring it leads to a larger sinkhole. We scan the area with thermal imaging cameras to confirm the leak is irrigation-related. Then we trace the line with pipe inspection cameras and repair the damaged section of PVC pipe or PEX tubing.
Zone loses pressure or will not turn on
A zone that will not pressurize usually has a broken lateral line or a failed valve. The rest of the system may still be running, wasting water through the break. We isolate the zone with pressure testing gauges and listen for the leak with acoustic tools. If the valve is the problem, we replace it. If the line is broken, we excavate and repair it.
Water bubbling up near the foundation
An irrigation break near the house can push water against the foundation. That leads to foundation leaks, basement dampness, and costly waterproofing. We locate the break with tracer gas detection and repair it fast. Then we check the foundation for signs of water intrusion. Catching it early saves thousands in waterproofing.

Customer stories
What Nashua Neighbors Say About Us
Dave M.Homeowner, Crown Hill
My water bill jumped from $80 to $310 in one month. I called Nashua LeakDetectors and they found a broken lateral line under my front lawn in about 40 minutes. They marked it, dug one small hole, and had it repaired the same afternoon. The bill went back to normal the next cycle. Worth every penny.
Karen S.Homeowner, Nashua Highlands
I had a soggy spot near my foundation that I thought was a slab leak. Their technician used a thermal camera and showed me it was actually an irrigation break pushing water toward the house. He fixed the sprinkler line and checked the foundation for free. Honest and thorough.
Tom R.Property Manager, Main Street District
We manage six commercial properties in Nashua. Nashua LeakDetectors handles all our irrigation leak calls. They show up when they say they will, they document everything with photos, and their pricing is flat. I do not have to chase them for reports. That is rare in this trade.
How much does sprinkler system leak detection cost in Nashua NH?
Most residential detection jobs in Nashua run $180 to $450 in 2026, depending on how many zones we test and whether the leak is under concrete. That price includes the full pressure test, acoustic scan, and thermal imaging. Repair is quoted separately once we know the pipe material and depth. We give you the detection price upfront before we start.
How do I find a sprinkler leak in my Nashua yard?
Start by running each zone for 10 minutes and watching your water meter. If the meter spins with the zone on and stops when it is off, you have a leak in that zone. Look for spongy grass, a constant wet spot, or a geyser at a head. If you cannot narrow it down, call us. We find the exact spot with acoustic and thermal tools in under an hour.
Can you detect a sprinkler leak without digging in Nashua?
Yes. We locate more than 90 percent of irrigation leaks without any excavation. Acoustic listening devices hear the water escaping, and thermal imaging cameras see the temperature difference in saturated soil. We mark the spot, confirm it with a second tool, and only then dig a small access hole. The hole is usually the size of a dinner plate.
