Copper Service Line Installation in Pomona, CA
Type K copper is a tough option for underground water lines. It resists punctures and lasts for decades. Copper costs more than PEX but is favored by some homeowners. We install copper with proper bedding to cushion it. We can also install sleeves where it passes through foundations.

PEX Water Line Installation in Pomona, CA
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. On an occasional cold night, covering backflow preventers and outdoor valves is typically enough to avoid a break. PEX can expand and contract without bursting, which is a real advantage when a cold snap hits Pomona. Its flexibility allows for fewer fittings and quicker installation.

Water Line Upgrades and Code Compliance in Pomona, CA
Beyond simple replacement, we also offer water line upgrades to improve water flow or ensure compliance with current plumbing codes. Older homes in Pomona might have undersized or outdated galvanized steel pipes that restrict flow and cause rust-colored water. We can replace these with larger diameter copper or PEX lines, bringing your system up to modern standards and improving overall water pressure and quality.
Commercial Water Line Replacement in Pomona
Beyond residential services, FKM Plumbing also provides robust commercial water line replacement in Pomona. Businesses, schools, and industrial facilities rely on strong, steady water service. We handle larger diameter pipes and more complex installations, ensuring minimal downtime for your operations. Our commercial services are matched to meet the specific demands and codes for various business types, utilizing durable materials designed for heavy usage.
Traditional Water Line Excavation in Pomona
Sometimes, traditional open-trench excavation is the most appropriate method for water line replacement in Pomona, 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 avoid future issues.
Main Water Line Repair vs. Replacement in Pomona
Deciding between repair and full replacement depends on the extent of the damage. If your main water line in Pomona has multiple leaks, severe corrosion, or is nearing the end of its lifespan, replacement is often the more cost-effective 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.

Pressure Regulator and Shutoff Upgrades in Pomona, CA
Many homes have high street pressure that can stress pipes and fixtures. We install pressure reducing valves set to a healthy range. We also replace old gate valves with full-port ball valves at the house. This makes it simpler to shut off water in an emergency. These upgrades protect your plumbing system.
