Galvanized Main Line Replacement in St. Peters
Galvanized steel pipe was common in homes built before the 1970s. Over time, it corrodes inside and chokes the pipe. This causes low pressure and discolored water. We replace galvanized lines with modern PEX or copper. The difference in water pressure is often immediate.

Pressure Regulator and Shutoff Upgrades in St. Peters, MO
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 safeguard your plumbing system.
Copper Water Line Installation in St. Peters
Copper has long been a preferred material for water lines due to its durability, corrosion resistance, and longevity. FGV Plumbing specializes in installing new copper water lines, known for their ability to withstand high water pressure and resist bacterial growth.

For homeowners looking to minimize disruption to their landscaping, trenchless water line replacement offers an excellent alternative.

Frequently Asked Questions About Water Line Replacement in St. Peters
The cost of water line replacement in St. Peters can vary significantly based on factors like pipe material (copper vs. PEX), length of the line, depth, and whether trenchless methods are used. In most cases, homeowners can expect to pay anywhere from $3,000 to $15,000 or more for a complete main water line replacement. We provide a detailed, upfront estimate after an on-site inspection.
Most residential replacements take one to two days. Bigger properties may take longer.
We install PEX and Type K copper. Both are long-lasting and code approved for underground use.
In many cases, yes. Trenchless methods cut down on digging, though some access pits are needed.
A newly installed water line using quality materials like copper or PEX can last 50 to 100 years or even longer. Copper is known for its exceptional longevity, while PEX typically has a manufacturer's warranty of 25 years but can last much longer. Regular maintenance and stable ground conditions contribute to a longer lifespan.
FGV Plumbing stands behind our work with comprehensive warranties on both parts and labor for water line replacements. The exact warranty period can vary based on the materials used and the scope of the project, but we will always provide you with full details in writing before any work begins, ensuring peace of mind.
A newly installed copper water line can last 50 to 70 years or even longer. PEX water lines are also very durable, with an expected lifespan of 40 to 50 years. The longevity depends on factors like water quality, soil conditions in St. Peters, and the quality of the install.
Basements are common in many areas, so sump pumps and drain tile are an important part of keeping homes dry. Shifting ground puts real stress on underground pipes, often leading to cracks and breaks. In addition, tree roots seeking water can aggressively penetrate and damage water lines over time, common issues we address in St. Peters, MO.
