Well Pump and Pressure Tank Replacement in St. Louis, MO
Rural properties rely on well pumps to deliver water, and pump failure means no water at all. Common signs include pressure that fluctuates, a pump that cycles rapidly or no water at the tap. We replace submersible and jet pumps and waterlogged pressure tanks with correctly sized equipment. Pressure switch settings are adjusted for steady pressure throughout the home.

Well Pressure Tank Replacement in St. Louis
If your well pump is cycling too frequently or you have inconsistent water pressure, your pressure tank might need replacing. FGV Plumbing installs new well pressure tanks, so your well system operates efficiently and your well pump lasts longer. We correctly size the tank to your system in St. Louis, improving water delivery and energy usage.
Pipe Replacement & Whole-Home Repiping in St. Louis, MO
Homes in St. Louis, MO with older galvanized steel or polybutylene pipes often experience low water pressure, discolored water or frequent leaks. A whole-home repipe with new PEX or copper piping can dramatically improve water quality and pressure and eliminate leak concerns. We carefully plan and complete repiping projects, minimizing disruption and making sure all new pipes are properly routed, insulated and connected, providing a durable and efficient plumbing system for many years.
Whole-Home Pipe Replacement in St. Louis
Homes with multiple pinhole leaks, galvanized pipe or polybutylene may benefit from a complete repipe. We replace supply lines with PEX or copper, often rerouting through the attic to avoid future slab leaks. Most repipes take two to four days with water restored each evening whenever we can. Drywall openings are patched when the work is finished.
Repair vs Replacement Cost Comparison in St. Louis, MO
A common rule of thumb is to replace when a repair costs more than half the price of new equipment or when the item is near the end of its useful life. Replacement also makes sense when repeated repairs are adding up. We give you side-by-side pricing for repair and replacement so you can decide with real numbers. Many replacements also improve efficiency and lower future repair costs.
Sewer Line Replacement in St. Louis
Persistent sewer backups, foul odors or lush spots in your yard can signal a failing sewer line. Basements are common in many areas, so sump pumps and drain tile are an important part of keeping homes dry. We offer complete sewer line replacement using trenchless technology whenever possible, limiting disruption to your landscaping. For more severe damage, traditional excavation is performed with careful attention. We make sure new lines are properly graded, connected and compliant with local St. Louis plumbing codes, preventing future blockages and costly repairs.
Gas Line Replacement in St. Louis
Old or damaged gas lines pose a serious safety risk and require immediate attention. If you suspect a gas leak or your gas lines show signs of corrosion or age, our certified plumbers in St. Louis can perform safe and code-compliant gas line replacement. We use approved materials like black steel pipe or corrugated stainless steel tubing (CSST) for secure installations, making sure all connections are leak-tested and meet strict safety regulations for your home's protection.

Sump Pump and Well Pump Replacement in St. Louis, MO
