A sudden increase in your water bill may indicate a hidden leak in your home's water service line. Even a small underground leak can waste thousands of gallons of water over time.
If water pressure has noticeably decreased throughout your home or business, a damaged or leaking water line may be restricting water flow and should be professionally inspected.
Soggy patches, standing water, or unusually green grass may indicate an underground water line leak. Prompt repairs can help prevent further property damage and water loss.
Rust-colored or cloudy water can sometimes indicate corrosion or damage within your water line. If your water suddenly changes color, it's important to have your plumbing system inspected.
Underground water leaks can wash away soil beneath concrete surfaces, potentially causing cracks, uneven settling, or sinking sidewalks and driveways.
If you hear water running when no plumbing fixtures are being used, your water service line may have a hidden leak that requires professional diagnosis.

A broken water line can quickly cause extensive property damage and water loss. If you're experiencing a major water line leak, Thomas Plumbing Inc. provides prompt emergency plumbing services to help protect your home or business.
Water lines can become damaged due to age, corrosion, shifting soil, tree root intrusion, high water pressure, or accidental damage during excavation. Identifying the cause helps ensure the repair addresses the underlying problem and helps reduce the likelihood of future issues.

Over time, water service lines naturally deteriorate due to age, corrosion, and daily use. Older water lines are more likely to develop leaks, cracks, or reduced water flow and may eventually require replacement.
Mineral deposits and corrosion can weaken metal water lines over time. As corrosion progresses, pipes become more susceptible to leaks, reduced water pressure, and eventual failure.
Natural soil movement caused by seasonal changes, settling, or nearby construction can place stress on underground water lines, leading to cracks, loose connections, or broken pipes.
Tree roots naturally seek moisture and can place pressure on underground water lines. In some cases, roots may damage or displace buried piping, leading to leaks and reduced water flow.
Excessively high water pressure places added stress on pipes, fittings, valves, and plumbing fixtures. Over time, this increased pressure can contribute to leaks and premature pipe failure.
Excavation, landscaping projects, fence installations, and other digging activities can accidentally damage underground water lines. Prompt repairs help restore water service and prevent additional property damage.

Common signs include an unusually high water bill, low water pressure, wet areas in your yard, discolored water, or the sound of running water when no fixtures are being used. A professional inspection can determine whether your water line is damaged.
