Water Line Installation and Replacement in Charleston
From replacing old, corroded pipes to installing new water lines for additions or renovations, KBN Plumbing provides complete water line installation in Charleston. We work with various materials, including PEX and copper, making durable, leak-free connections. Red clay dominates much of the upstate, while the coastal plain of South Carolina has sandy soil and a shallow water table that affects drainage and digging. We use bedding and burial techniques that reduce future issues with buried lines. We also ensure proper pressure regulation and backflow prevention devices are installed where needed to protect your potable water supply.

Tankless Water Heater Installation in Charleston, SC
Tankless water heaters from Navien, Rinnai and Rheem deliver endless hot water and save space in garages and closets. Gas units usually need a larger gas line and new venting, while electric units often need added amperage. We size the unit by flow rate and incoming water temperature. High humidity speeds up corrosion on exposed copper and fittings in crawlspaces, so a quick look under the house is worth doing every year. We also install isolation valves for future flushing.
Sump Pump and Sewage Ejector Pump Installation in Charleston
Protecting your Charleston home from water damage is crucial, especially in areas prone to heavy rains or with basements. KBN Plumbing installs reliable sump pumps to remove excess water from crawl spaces and basements. For homes with plumbing fixtures below the main sewer line, we also install robust sewage ejector pumps to safely move wastewater. Proper sizing and placement are key, and we ensure your pump has a dedicated circuit and correct discharge piping for optimal performance.
PEX Pipe Installation in Charleston, SC
PEX piping has become a popular choice for new plumbing installations and repipes in Charleston, SC due to its flexibility, durability, and resistance to corrosion. KBN Plumbing installs PEX piping for water supply lines, offering a cost-effective and long-lasting alternative to copper. Its ability to expand makes it more resistant to freeze damage than rigid pipe. Before a forecast freeze, disconnecting garden hoses, covering hose bibs and letting a faucet drip is usually enough to protect a home. We make sure all connections are secure and leak-free.
Sump Pump Installation in Charleston, SC
Protecting your basement from flooding is important in Charleston, SC, especially during heavy rainfalls. KBN Plumbing provides professional sump pump installation, including primary and battery-backup systems. We evaluate your basement's water intrusion risks, soil conditions, and foundation type to recommend the right pump capacity and discharge setup. Proper pit excavation, check valve installation, and discharge line routing away from your foundation are key steps we manage with care. Our team makes sure your new sump pump is ready to handle any excess water, preventing costly damage.
Water Heater Installation in Charleston
KBN Plumbing specializes in installing all types of water heaters, including conventional tank models and advanced tankless units, for homes in Charleston. We help you choose the right size and energy source, gas or electric, to meet your family's hot water demands and budget.

Water Line Installation in Charleston
Whether you're replacing old, corroded galvanized pipes or installing new water lines for an addition, KBN Plumbing has you covered. We work with various materials like PEX and copper, ensuring durable, leak-free connections. Hard water can lead to mineral buildup, making proper pipe selection and installation important for longevity. Most municipal water in South Carolina comes from rivers and reservoirs, so it tends to run fairly soft and leaves less scale than in many other states. We handle everything from the main water service line into your home to individual fixture supply lines, following all local regulations for trenching, backfilling, and pressure testing.

Sewage Ejector Pump Installation in Charleston, SC
When plumbing fixtures are located below the main sewer line, such as in a basement bathroom or laundry room, a sewage ejector pump is needed.

We ensure correct sizing of the pump and basin, proper venting, and secure discharge line connection to the main sewer. This complex installation requires specialized knowledge to prevent backups and ensure reliable waste removal.

Frequently Asked Questions About Plumbing Installation in Charleston
Costs depend on the project. A standard tank water heater install usually runs $1,600 to $3,500, a water softener $1,500 to $4,000, and a whole-home PEX repipe $5,000 to $15,000 or more depending on home size.
A water heater or softener install typically takes a few hours. Gas line runs and water line replacements can take a day, while whole-home repipes may take several days.
Signs that your plumbing system in Charleston may need replacement include frequent leaks, rust-colored water, consistently low water pressure throughout the house, and visible corrosion on exposed pipes. If your home has older galvanized or lead pipes, a full repipe can greatly improve water quality and system reliability.
You probably need a sump pump if your Charleston home has a basement or crawl space that experiences water seepage, dampness, or has flooded in the past. Homes built in low-lying areas or with high water tables are especially susceptible. An assessment by KBN Plumbing can determine the best waterproofing and sump pump solution for your property.
In Charleston, most backflow preventers are required to be tested annually by a certified technician to ensure they are functioning correctly. This is crucial for maintaining the safety of your public water supply. KBN Plumbing offers convenient annual testing and certification services.
Tank water heaters cost less upfront, while tankless units offer endless hot water and can last longer. We help you compare based on household size, fuel type and budget.
Most municipal water in South Carolina comes from rivers and reservoirs, so it tends to run fairly soft and leaves less scale than in many other states. A water softener prevents mineral buildup in pipes and appliances, extending their lifespan and improving efficiency. Softened water also leaves skin and hair feeling cleaner and helps soaps and detergents lather more effectively, reducing their usage.
Equipment carries the manufacturer's warranty, often 6 to 12 years for water heaters. We also warranty our installation workmanship.
