Water Main Underground Repair in Fullerton
A leaking or broken water main can lead to major water loss and property damage. FKM Plumbing provides expert repair for underground water mains, using durable materials like PEX or copper for a long-lasting fix. We can promptly locate the break using non-invasive methods and restore your home's water supply with minimal disruption.

Foundation Leak Detection and Repair in Fullerton, CA
Leaking pipes beneath a slab foundation are a serious issue that often requires specialized underground repair. We use advanced acoustic and thermal imaging to detect slab leaks without destructive testing. Once located, we provide precise repair solutions, from re-routing lines to targeted slab penetration, to protect your home's structure in Fullerton, CA.
Galvanized and Polybutylene Line Replacement in Fullerton
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.
Storm Drain and Lateral Repair in Fullerton, CA
Underground storm drains and laterals are essential for managing rainwater runoff and preventing flooding around your property. Damage to these pipes can lead to water pooling, erosion and foundation issues. We inspect, clear and repair damaged storm drainage systems, restoring proper water diversion and protecting your landscape and structures in Fullerton, CA from water damage.

Underground Pipe Repair Cost Comparison in Fullerton, CA
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.
Polybutylene Pipe Replacement in Fullerton
Many homes built in the 1980s and 1990s may have polybutylene pipes, which are prone to sudden failure due to their material composition. If you have polybutylene in your underground water lines, proactive replacement is often recommended. We specialize in safely removing and replacing these problem pipes with modern, durable alternatives, preventing future leaks in Fullerton.

Frequently Asked Questions About Underground Pipe Repair in Fullerton
The cost of underground pipe repair in Fullerton, CA can vary widely, typically ranging from $500 for minor spot repairs to $3,000 to $10,000 or more for trenchless full line replacements, or even more for extensive excavation and re-piping. Factors include the pipe material, depth, length of the damaged section, the repair method chosen and the extent of property restoration needed. We provide transparent, upfront pricing after a thorough diagnosis.
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.
FKM Plumbing is equipped to repair a wide range of underground pipe materials, including PVC, ABS, cast iron, copper, PEX and even older materials like clay or polybutylene. Our technicians are trained on the specific repair techniques for each material.
Many water utilities offer a one-time leak adjustment if you repair the leak quickly and provide proof. We give you an invoice and repair documentation to support your request.
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.
Look for unusually wet spots in your yard, unexplained increases in your water bill, foul odors, decreased water pressure or gurgling sounds from drains. These can all point to a hidden leak or blockage in your underground plumbing system.
The length of an underground pipe repair depends heavily on the severity and location of the damage, as well as the repair method chosen. Minor repairs using trenchless techniques might be completed in a single day. More extensive issues, such as full sewer line replacements requiring excavation, could take two to five days, including restoration work.
