High Water Bill & Hidden Irrigation Leak Detection in Cary & Raleigh, NC
Finding underground sprinkler leaks and water waste before they become costly problems
If your water bill suddenly spikes and your household usage hasn’t changed, your irrigation system may be leaking underground. Hidden sprinkler leaks are one of the most common causes of unexplained high water bills in Cary and Raleigh.
Because irrigation pipes are buried, small breaks can go unnoticed for weeks or months. At Cary Sprinklers, we specialize in identifying hidden irrigation leaks and restoring efficient system performance.
Signs Your Sprinkler System May Be Leaking
- Sudden increase in monthly water bill
- Constant damp or soft areas in lawn
- Uneven grass growth in one section
- Water meter running when irrigation is off
- Reduced pressure in certain zones
- Valve box repeatedly filling with water
How Hidden Irrigation Leaks Occur
Underground sprinkler lines can crack from soil shifting, root intrusion, aging PVC, freeze expansion, or accidental contractor damage. Even a small fracture under pressure can waste thousands of gallons over time.
Main Line vs Zone Line Leaks
Main line leaks occur before zone valves and may leak continuously. Lateral zone leaks only appear when a zone runs. Proper diagnosis is essential for accurate repair.
Our Leak Detection Process
Water Meter Verification
We confirm whether water flow continues when the system is idle.
Zone Isolation Testing
Zones are activated individually to pinpoint pressure irregularities.
Visual & Soil Inspection
Surface clues and soil moisture patterns help localize underground issues.
Targeted Excavation
Only the affected section is exposed for repair.
Why Fast Detection Matters
Hidden leaks can lead to soil erosion, foundation moisture issues, and increased utility costs. Early detection limits damage and reduces long-term expense.
Water Efficiency in Cary & Raleigh
Clay soil absorbs water slowly. Prolonged leakage can create saturated pockets that weaken turf and landscaping.
