Copper Water Line Installation in San Diego
Copper has long been a popular material for water lines due to its durability, corrosion resistance, and longevity. FKM 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 reliable and long-lasting water supply system, a great choice for many homes in San Diego, CA.

Traditional Water Line Excavation in San Diego
Sometimes, traditional open-trench excavation is the most practical method for water line replacement in San Diego, especially for severe damage, complex pipe layouts, or when the existing pipe material is incompatible with trenchless techniques. Our team methodically 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.
PEX Water Line Installation in San Diego, CA
PEX (cross-linked polyethylene) piping is a modern, flexible, and increasingly popular choice for water line replacement. It resists corrosion, scaling, and chlorine, making it very durable for most water conditions. Mountain and high desert communities in Southern California do get hard freezes, so pipes there need insulation and proper winter care. PEX can expand and contract without bursting, which is a significant advantage when a cold snap hits San Diego. Its flexibility allows for fewer fittings and faster installation.
PEX Water Line Replacement in San Diego
PEX (cross-linked polyethylene) is a popular and budget-friendly choice for water line replacement in San Diego. It's flexible, resistant to freezing, and less prone to scaling and corrosion than some traditional materials. Its flexibility allows for easier installation, often requiring fewer connections, which reduces the potential for leaks. PEX is also a good option for homes with aggressive soil conditions, offering a reliable alternative to metal pipes.
Commercial Water Service Replacement in San Diego
Commercial properties often have larger service lines and backflow assemblies. We replace commercial water lines and work with the utility when needed. We schedule work to reduce disruption to tenants and customers. Backflow devices are tested and certified. We handle permits and inspections.

Main Water Line Repair vs. Replacement in San Diego
Deciding between repair and full replacement depends on the extent of the damage. If your main water line in San Diego has multiple leaks, severe corrosion, or is nearing the end of its lifespan, replacement is often the more sensible long-term solution. Our technicians will perform a thorough inspection, including pressure testing and possibly video inspection, to recommend the best course of action. We consider factors like the age of your home, the material of the existing pipe, and the nature of the damage before making a recommendation.
