PEX Water Line Installation in Exeter, NH
PEX (cross-linked polyethylene) piping is a modern, flexible, and very popular choice for water line replacement. It resists corrosion, scaling, and chlorine, making it highly durable for most water conditions. Pipes in exterior walls, crawlspaces, camps and seasonal homes are especially likely to freeze when the heat is turned down. PEX can expand and contract without bursting, which is a significant advantage when a cold snap hits Exeter. Its flexibility allows for fewer fittings and faster installation.

Copper Water Line Installation in Exeter
Copper has long been a popular material for water lines due to its durability, corrosion resistance, and longevity. FVR Plumbing specializes in installing new copper water lines, known for their ability to withstand high water pressure and limit bacterial growth. While a higher upfront investment, copper provides a dependable and long-lasting water supply system, a great choice for many homes in Exeter, NH.
Damage Assessment and Replacement in Exeter
Diagnosing the exact cause and extent of water line damage is crucial before replacement. Our technicians use advanced leak detection equipment and camera inspections to pinpoint issues like tree root intrusion, pipe corrosion, or ground shifting. For properties in Exeter, especially those with older foundations or significant tree growth, accurate assessment ensures we recommend the most appropriate and effective replacement strategy.
Traditional Water Line Excavation in Exeter
Sometimes, traditional open-trench excavation is the most practical method for water line replacement in Exeter, especially for severe damage, complex pipe layouts, or when the existing pipe material is incompatible with trenchless techniques. Our team carefully excavates the area, removes the old pipe, and installs a new, high-quality main water line, typically using copper or PEX. We ensure proper grading and compaction of the soil during backfilling to prevent future issues.
Main Water Line Replacement in Exeter
The main water line is the primary pipe carrying water from the municipal supply to your home. When this critical line fails due to age, shifting soil, or severe leaks, a full replacement is often the most sensible long-term solution. We carefully excavate, remove the old line, and install new, durable piping, ensuring proper connection to your home's plumbing system and the city's main.
Copper Service Line Installation in Exeter, NH
Type K copper is a durable option for underground water lines. It resists punctures and lasts for decades. Copper costs more than PEX but is preferred by some homeowners. We install copper with proper bedding to cushion it. We can also install sleeves where it passes through foundations.
