Underground Storm Drain Repair in New Haven, CT
Clogged or damaged underground storm drains can lead to serious flooding and foundation issues, especially during heavy rain. Heavy downpours can overload older sewer systems and push water back into basements, so a backwater valve can be a sensible upgrade. GLV Plumbing focuses on repairing and clearing these vital drainage systems. We address blockages, cracks and disconnections to restore proper water runoff and protect your New Haven property.
Main Water Line Repair in New Haven
Your main water line runs from the meter box to the house and is under constant pressure. When it leaks, you may notice a spinning meter dial with all fixtures off, low pressure or a wet spot that never dries. We locate the leak, expose the pipe and splice in a new section with approved fittings. If the line is old galvanized or polybutylene, we will recommend a full replacement before more breaks happen.
Underground Pipe Repair Cost Comparison in New Haven, CT
A single point repair on a shallow water line is the most economical option. Pipe bursting or pulling a new line through the old path costs more but avoids open trenching and long-term risk. Full trench replacement is sometimes needed when the old route is blocked or the pipe is too damaged. We explain each method and its cost so you can choose the best value.
Underground Sewer Line Repair in New Haven, CT
Buried sewer laterals crack from root intrusion, soil settling and age. We camera the line to find the exact spot, then excavate and replace the damaged section with PVC. Shielded couplings make a watertight connection to the existing pipe. We confirm proper slope and flow before backfilling and compacting the trench.

Trenchless Pipe Repair in New Haven
Trenchless pipe repair offers a less invasive alternative to traditional excavation for buried pipe issues. Methods like pipe bursting or pipe lining allow us to repair or replace damaged pipes with minimal digging, preserving your landscaping, driveways and foundations in New Haven. This approach saves time and reduces restoration costs, making it ideal for many homeowners.

The time of an underground pipe repair depends on the complexity. A minor leak repair might take a few hours, while a full trenchless sewer line replacement could take one to three days. We always aim for efficient service with minimal disruption.
Common signs of a broken underground pipe include unexplained wet spots or lush patches in your yard, a sudden drop in water pressure, unusual odors such as sulfur or sewage, gurgling sounds from drains or toilets or an unexpected increase in your water bill. If you notice any of these, it's smart to call for a professional inspection promptly.
