8 Signs That You Have Water Pipe Damage

Undetected water pipe damage can cost facility owners and water utilities tens of thousands of dollars in emergency repairs and non-revenue water loss before the source of the problem is ever found. The signs are often subtle: a spike in your water bill, a gradual drop in pressure, or unexplained wet spots on a lawn or floor. Each one points to something happening underground. Knowing what to look for, and acting quickly, is the difference between a targeted repair and a crisis.

8 Signs That You Have Water Pipe Damage

Undetected water pipe damage can cost facility owners and water utilities tens of thousands of dollars in emergency repairs, non-revenue water loss, and structural damage before the source of the problem is ever found. Knowing the signs early, and acting on them quickly, is the difference between a targeted repair and a crisis.

Here are eight signs that point to water pipe damage, and what each one tells you about what may be happening underground.

1. A Spike in Your Water Bill

An unexplained increase in your water bill is one of the most common early indicators of a water pipe leak. If usage patterns have not changed but the bill has risen significantly, water is leaving your system somewhere between the meter and the point of use. For commercial and municipal systems, even small percentage losses compound quickly into substantial non-revenue water (NRW) costs.

2. Low Water Pressure

A drop in water pressure across a facility or section of a distribution system can indicate a leak, a partial blockage, or pipe deterioration. When pressure drops suddenly rather than gradually, a break or significant leak is more likely. Gradual pressure decline over time may point to buildup or corrosion narrowing the pipe interior.

3. Discolored Water

Brown, red, or yellow water is typically a sign of corrosion inside the pipe. Rust particles entering the water supply indicate pipe wall degradation, which can eventually lead to a breach. Discolored water is both a pipe health indicator and a water quality concern that warrants immediate investigation.

4. Wet Spots or Unexplained Puddles

Persistent wet areas on a lawn, parking lot, or facility floor that cannot be attributed to rain or irrigation are a direct indicator of water escaping from a buried line. The wet zone may not be directly above the leak, as water follows the path of least resistance through soil and can surface some distance from the break. GPRS Video Pipe Inspection (VPI) services can help identify the source and extent of damage in buried lines without excavation.

5. Higher Than Normal Water Usage

If your facility’s water consumption is running above historical averages without a corresponding change in operations, the excess water is going somewhere. Continuous meter movement when all fixtures are off confirms active leakage. Many facilities first identify this pattern during routine meter audits or when reviewing monthly consumption reports.

6. Cracks in Walls, Floors, or Foundation

Water escaping from underground pipes erodes the soil that supports the structure above it. Over time, this creates voids that cause settlement, cracking, and in severe cases, structural instability. Cracks appearing in areas near underground pipe routes, or in areas with no obvious structural explanation, should trigger a pipe investigation, not just a structural repair.

7. Mold or Mildew Growth

Mold and mildew require sustained moisture to develop. When they appear in areas not exposed to obvious water sources, a concealed leak in a wall cavity, under a floor, or in a crawl space is a likely cause. Mold remediation without locating and repairing the moisture source will result in recurrence.

8. The Sound of Running Water

Audible water movement when no fixtures are in use, particularly sounds coming from walls, floors, or ground areas near buried lines, is a strong indicator of active leakage. Acoustic leak detection equipment uses this same principle at a professional level, amplifying the distinctive sounds produced by pressurized pipe leaks to pinpoint their location without excavation.

What to Do If You See These Signs

GPRS, the nation's largest private utility locating company, deploys acoustic leak detectors, leak noise correlators, and video pipe inspection (VPI) equipment to locate the source of water pipe damage without excavation. Our water loss specialists can pinpoint a known leak or conduct a proactive survey of your water or fire suppression system to identify problems before they become emergencies.

All leak detection and VPI findings are stored in SiteMap®, GPRS' secure infrastructure management platform, giving your facility team a permanent record of pipe conditions that supports maintenance planning, capital improvement decisions, and regulatory documentation.

Contact GPRS to schedule a leak detection service or video pipe inspection or request a quote for a proactive water loss survey of your facility.
