Our Main Line Leak Detection Services
Our main line leak detection services provide a focused inspection of the water line that supplies your home. We use proven techniques and advanced equipment to determine whether there is a leak, where it is located, and how extensive the issue may be.
This includes:
- Ultrasonic or acoustic leak detection
- Video pipe inspection
- Thermal imaging
- Chemical testing
- Pressure testing
Our technicians inspect for leaks in your main water line, service line, and other underground water supply components. After locating the issue, we’ll explain our findings, recommend appropriate next steps, and provide an estimate for any necessary repair work.
Our team will also provide a reliable estimate of how long the work may take. Some main line issues can be resolved quickly, while more extensive underground repairs may require additional time.
Signs You May Have a Main Line Leak
Main line leaks can be difficult to spot because much of the pipe is buried underground. Contact us if you notice:
- Low water pressure: If your water pressure has decreased, it could be due to a leak in your plumbing system.
- Constantly running water meter: If your water meter continues to run, a leak may be the cause.
- Increase in water bills: If your bills have increased but your water usage hasn’t, it could be a sign of a hidden leak.
- Dampness or mold: Mold, patches of dampness, or mildew on floors, walls, or ceilings point to a leaking pipe.
- Unusual noises: Sounds of running water when pipes aren’t in use might indicate a leak.
