A problem with your main water line can shut off your home’s entire water supply or quietly waste thousands of gallons underground before you notice a spike in your water bill. Sudden pressure drops, wet spots in the yard, or unexplained increases in your water bill are all signs your water line needs professional attention.
TMS provides water line repair and replacement services for homeowners throughout Connecticut, using both trenchless and traditional methods to restore reliable water service with minimal disruption to your property.
What Is a Water Line and Why Does It Fail?
Your water line, also called the water service line or main water line, is the pipe that carries fresh water from the municipal main or well into your home. It typically runs from the street or well to your water meter or shutoff valve, often several feet underground.
Water lines fail for several common reasons:
- Age and material: Older galvanized steel or lead water lines corrode from the inside out over time.
- Soil movement: Connecticut’s freeze-thaw cycles shift soil, which can crack or separate pipe joints.
- Tree root intrusion: Roots seeking moisture can crack pipes or infiltrate joints, especially in older clay or cast iron lines.
- Corrosion: Acidic soil and water chemistry gradually deteriorate metal piping from the outside in.
- Physical damage: Excavation, construction, or heavy equipment near the line can cause sudden breaks.
Signs You Need Water Line Repair
Water line problems aren’t always obvious right away. Watch for:
- Sudden drop in water pressure throughout the house
- Unexplained wet or soggy patches in the yard, especially in dry weather
- A noticeably higher water bill with no change in usage
- Discolored water when you first turn on a tap
- The sound of running water when no fixtures are in use
- No water at all, or water that stops and starts
If you notice any of these signs, don’t wait: a small leak underground can quickly become a much larger, more expensive repair.
Our Water Line Repair & Replacement Process
1. Leak Detection and Diagnosis: We use professional leak detection equipment to pinpoint the exact location and severity of the problem without unnecessary digging.
2. Clear Recommendations: Once we’ve assessed the line’s condition, material, and depth, we explain your repair and replacement options along with upfront pricing.
3. Trenchless or Traditional Repair: Depending on the damage and your property, we recommend either a trenchless method, which limits digging and preserves landscaping, or traditional excavation for severely damaged lines.
4. Testing and Restoration: After repair or replacement, we pressure-test the new line to confirm proper flow and a leak-free connection, then restore the work area.
