Water and Sewer Line Slab Leaks in New Haven, CT
Slab leaks can affect both freshwater supply lines and sewer drain pipes. Our detection services are set up to identify both types of leaks, which present different challenges. Sewer line leaks often involve foul odors and slow drainage, while water line leaks can appear as wet spots or high water bills in your New Haven, CT home. We have specific methods for each.

Acoustic Slab Leak Detection in New Haven
Our technicians rely on highly sensitive acoustic listening devices to pinpoint the exact location of a leak under your slab. This method involves listening for the faint sound of escaping water, even through concrete. It's particularly effective for pressurized water lines, allowing us to find leaks without unnecessary excavation and minimizing disruption to your New Haven home.
Emergency Slab Leak Detection in New Haven
A sudden drop in water pressure, visible dampness or the sound of running water can signal an emergency slab leak. GLV Plumbing offers emergency detection services in New Haven to address urgent situations quickly. We prioritize rapid response to limit water damage and prevent further structural compromise to your property.
Emergency Slab Leak Response in New Haven
A slab leak that is flooding floors or causing water to bubble up through tile needs quick attention. We respond quickly, help you shut off the water and isolate the leaking side if possible. That often lets you keep partial water service until the repair. Then we locate and fix the leak.
Electronic Leak Detection in New Haven
For hard-to-find leaks, our electronic leak detection equipment sends a signal through your pipes and measures changes that indicate a breach. This technology allows us to locate leaks in many pipe materials, including copper, PEX and PVC, commonly found in New Haven homes. It helps prevent exploratory digging, saving you time and money.
Repiping After Multiple Slab Leaks in New Haven, CT
If your home has had two or more slab leaks, the remaining pipe is likely corroded too. Repiping replaces all supply lines with new PEX or copper run through the walls and attic. It is a bigger project, but it ends the cycle of repeat slab leaks. We can typically complete a full repipe in two to four days.
Pressure Testing & Isolation in New Haven
When a leak is suspected, we can perform pressure tests on individual water lines. By isolating sections of your plumbing system and monitoring pressure gauges, we can confirm the presence of a leak and often determine which particular line is compromised. This step-by-step approach is crucial for homes with complex plumbing layouts, ensuring an accurate diagnosis before any excavation in New Haven, CT.

Slab Leak Repair Through Direct Access in New Haven, CT
When a single leak is found on otherwise healthy pipe, direct access can be the most affordable repair. We cut a small opening in the floor at the marked spot, repair the pipe and pressure test it. Then we patch the concrete and leave the area ready for flooring. Accurate detection keeps that opening as small as it can be.
