Galvanized and Polybutylene Line Replacement in Hockessin
Galvanized steel pipe rusts from the inside, and polybutylene pipe becomes brittle and splits without warning. If your underground service is either material, repairs are often temporary. We replace the line with PEX or Type K copper, often by pulling the new pipe through the old path to limit digging. A new line restores pressure and removes the risk of repeated leaks.

No, DIY underground pipe repair is not recommended. These repairs require specialized equipment for detection and repair, knowledge of local plumbing codes and the ability to work safely around utility lines. Improper repairs can lead to further damage, costly fixes and potential health hazards from sewage or contaminated water. Always rely on licensed professionals.
GNV Plumbing stands behind the quality of our underground pipe repair work. We offer a solid warranty on parts and labor for all our underground pipe services, giving you peace of mind. Warranty details will be provided with your repair estimate, so you understand the protection you get.
Yes. Our repairs include a written workmanship warranty, and the pipe and fittings carry manufacturer warranties. We explain coverage before we begin.
We use acoustic listening devices that pick up the sound of escaping water, tracer gas that rises through soil at the leak point and electronic locators that trace the pipe path. Together these narrow the leak to a small area.
For water lines we typically use PEX or Type K copper, both approved for direct burial. For sewer lines we use Schedule 40 PVC. The right choice depends on the existing pipe and local code.
In most cities, the homeowner owns and maintains the water line from the meter to the house. The utility is usually responsible for the meter and the line on the street side. We can help confirm which side the leak is on.
Trenchless pipe repair offers several key advantages, including minimal disruption to your yard, landscaping and concrete, which can save on restoration costs. It's often faster than traditional excavation and less invasive, preserving the look and value of your property. This method is also durable, frequently extending the lifespan of your pipes.
