Plumbing Replacement in Charleston, SC for Equipment, Pipes and Sewer Lines
KBN Plumbing sees how fast hard water, heat and shifting soil can wear out plumbing. Private wells are common outside town limits, and some South Carolina well water carries iron, low pH or sediment that can stain fixtures and wear down water heaters. Water heaters scale up, softeners lose resin, well pumps burn out and old pipes corrode. We replace these components with quality equipment sized for your home and explain the expected lifespan of each.
Our expertise includes:
- Advanced Pipe Replacement Techniques
- Water heater and tankless unit replacements
- Tank, tankless and gas water heater replacement and code upgrades

Water Heater Replacement in Charleston
When your water heater is leaking, not heating or providing too little hot water, it is often more economical to replace it than to repair it, especially if it is over 10 years old. We install standard tank water heaters, sized properly for your home's needs and compliant with current energy efficiency standards. Our team handles the safe removal of your old unit and the careful installation of your new one, connecting gas or electric lines and confirming correct venting and pressure relief valve operation for performance and safety.

Sump Pump and Well Pump Replacement in Charleston, SC
For homes with basements or relying on well water, a working pump is critical. KBN Plumbing replaces faulty sump pumps and well pumps with high-quality, dependable models. We make sure of correct sizing and installation for effective water removal and consistent water pressure, protecting your Charleston home from flooding and keeping a steady water supply. We work with brands like Zoeller and Grundfos.
Whole-Home Pipe Replacement in Charleston
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 when possible. Drywall openings are patched when the work is complete.
Pipe Replacement & Whole-Home Repiping in Charleston, SC
Homes in Charleston, SC 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 decades to come.
Repair vs Replacement Cost Comparison in Charleston, SC
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 expected 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 reduce future repair costs.
Tankless Water Heater Replacement in Charleston, SC
Upgrade to endless hot water with a tankless water heater replacement. These units heat water on demand, saving energy and space, which is a great benefit for Charleston homes. We focus on replacing older tankless units or converting from traditional tank heaters to high-efficiency tankless models from brands like Rinnai and Noritz. Our service includes assessing your home's gas line capacity or electrical service, confirming proper venting and precise installation to maximize efficiency and longevity.
Water Line Replacement in Charleston, SC
A leaking main water line can lead to major water loss, high bills and foundation damage, which is a serious concern for homes on slab foundations. Our water line replacement services address issues like corroded pipes, leaks or low water pressure. We locate the leak, excavate the area if necessary and replace the damaged section or the entire line with durable PEX or copper piping. We make sure of a secure, leak-free connection from the meter to your home, restoring reliable water flow.

Well Pump & Pressure Tank Replacement in Charleston
For rural properties in and around Charleston that rely on well water, a failing well pump or pressure tank can leave you with no water at all.
