Trusted irrigation leak detection across the Triangle
Irrigation leak detection is how we track down a hidden underground leak in your sprinkler system before it wrecks your water bill or your yard. Cary Sprinklers does this work across the Triangle, and owner Adam stands behind every diagnosis so nothing gets guessed at. The goal is simple: find exactly where the water is escaping, then dig in one spot instead of tearing up the whole lawn.
Our clay soil makes leaks sneaky. Water from a mainline seep or a valve stuck barely open travels sideways underground and rarely bubbles up where the break actually is, so a section of the yard can stay soggy fifteen feet from the real problem. Cary’s reclaimed purple-pipe water adds grit that chews through nozzles and valve seats faster, which is often what starts a slow leak in the first place. Add in backflow rules that shift from town to town, and accurate irrigation leak detection matters more here than most homeowners expect.
We handle irrigation leak detection for homeowners in Cary, Raleigh, Apex, Morrisville, Holly Springs, Fuquay-Varina and throughout Wake County — part of our irrigation repair service.
Common irrigation leak detection problems we fix
Diagnosed right and fixed with genuine Hunter, Rain Bird & Toro parts.
Mainline seep
A cracked mainline or loose fitting can leak the whole time your system is pressurized, even between watering days. We isolate the mainline and confirm the loss before anyone touches a shovel.
Valve stuck open
A worn solenoid or a bit of purple-pipe grit under the diaphragm keeps a valve barely cracked, so one zone weeps around the clock. Irrigation leak detection here means pressure-testing zone by zone until the guilty valve shows itself.
Cracked lateral line
Freeze damage or a careless shovel splits a poly or PVC lateral, and the water follows the clay sideways instead of surfacing. We narrow it to the zone, then locate the break so the dig is small.
Leaking heads and nozzles
Rotors and spray heads that no longer seal at the base bleed water down into the soil every cycle. We check seals, wiper caps, and precip rates to catch the ones losing water underground.
Backflow and manifold leaks
A weeping RPZ, a hairline crack in a manifold, or a bad union near the backflow can mimic a buried leak. We rule these out early since they’re above ground and often the real culprit.
Fitting and joint failures
Glued joints and barbed fittings work loose over years of pressure swings and clay movement. Precise irrigation leak detection pins the exact fitting so we repair it instead of replacing good pipe.
Signs you need irrigation leak detection
- Water bill jumped with no change in habits
- A patch of lawn stays wet or spongy between waterings
- One zone has weak pressure or heads that barely pop up
- You hear water running when the controller is off
- Moss, mushrooms, or sunken soil over a buried line
How the work happens, step by step
No mystery, no runaround — here’s the order we work in.
Meter check
We start at the water meter to confirm the system is actually losing water and roughly how much. That tells us we’re chasing a real leak and not a scheduling or pressure quirk.
Zone-by-zone pressure test
We run and isolate each zone, watching pressure and flow to see which one won’t hold. This separates a mainline problem from a single lateral or valve.
Soil-moisture inspection
We read the ground across the suspect zone, since clay carries water sideways and the wet spot is rarely over the break. This keeps us from digging in the wrong place.
Precise locate and repair
Once we’ve narrowed it down, we pinpoint the leak so excavation stays small and your landscaping stays intact. We fix it with genuine parts and pressure-test the zone before we leave.

Why homeowners choose us
No rotating crews
Adam stands behind every leak we chase, and the same accountable local team sees it through, so the person reading the meter is the person who fixes the leak. That continuity is why irrigation leak detection here doesn’t turn into guesswork or a bigger job than it needs to be.
We dig once, not everywhere
Minimal, controlled excavation is the whole point of locating a leak precisely first. Your beds, sod, and roots stay put because we open one small spot instead of trenching the yard.
Honest diagnosis, backed in writing
We repair before we replace and give you upfront pricing before any work starts. Every job is covered by our satisfaction guarantee and a 12-month workmanship warranty.

Irrigation leak detection FAQ
How much does irrigation leak detection cost?
We give upfront pricing after we see the system, and the estimate is free. You’ll know the number before we start, and we won’t quote a dollar amount over the phone that we can’t stand behind on site.
Can you find a leak without digging up my whole yard?
Yes, that’s the point of doing it right. We use the meter, zone pressure tests, and soil readings to narrow the leak to one spot, so the actual digging is small and your landscaping is protected.
My water bill spiked but the lawn looks fine. Is that a leak?
Often it is. A mainline seep or a valve stuck barely open runs underground with almost nothing showing on the surface, and in our clay the water spreads sideways instead of pooling. A meter check will confirm whether the system is losing water.

If you searched irrigation leak detection near me anywhere in Cary, Raleigh, Apex, Morrisville, Holly Springs, Fuquay-Varina, or the rest of Wake County, you’re in our area. We work the whole Triangle and know how the local soil and reclaimed water affect these systems.
