Tankless Water Heater Installation in Columbia, 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. Warm weather for most of the year means water heaters, irrigation lines and outdoor fixtures in South Carolina see year-round use with little seasonal rest. We also install isolation valves for future descaling.

PEX Pipe Installation and Repiping in Columbia
PEX is flexible, resistant to scale and a popular choice for repiping older homes with failing copper or galvanized pipe. We install PEX with manifold or home-run layouts for balanced pressure. The material handles hard water well and can reduce noise in the walls. We patch access openings neatly or coordinate with your drywall contractor. A PEX repipe can stop repeat pinhole leaks.
Backflow Preventer Installation in Columbia
Backflow preventers are critical for protecting your home's drinking water from contamination, especially for irrigation systems, fire suppression lines, or homes with private wells. KBN Plumbing installs and tests backflow prevention devices in Columbia to ensure your water supply remains safe and compliant with health codes. We ensure the correct type of device is installed for your specific application and that it is properly maintained and tested annually.
Water Line Installation in Columbia
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 crucial for longevity. Even with softer supply water in Columbia, a yearly water heater flush still helps clear the sediment that settles in the bottom of the tank. 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.
Sump Pump and Sewage Ejector Pump Installation in Columbia
Protecting your Columbia home from water damage is important, 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 make sure your pump has a dedicated circuit and correct discharge piping for optimal performance.
Gas Line Installation in Columbia, SC
Whether you are adding a new gas appliance, converting to natural gas, or need a new line run for an outdoor kitchen, KBN Plumbing provides safe and compliant gas line installation in Columbia, SC. Our licensed technicians handle everything from sizing the line to trenching, ensuring all connections are leak-free and meet strict local codes. Gas line work requires specialized tools and expertise to prevent dangerous leaks, making professional installation essential for the safety of your home.
Sewage Ejector Pump Installation in Columbia, 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. KBN Plumbing provides professional sewage ejector pump installation in Columbia, SC. 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. We use durable pumps from trusted brands like Liberty Pumps or Zoeller to guarantee long-term performance.

Water Line Installation and Replacement in Columbia
From replacing old, corroded pipes to installing new water lines for additions or renovations, KBN Plumbing provides complete water line installation in Columbia. We work with various materials, including PEX and copper, making durable, leak-free connections. Most South Carolina homes sit on crawlspaces or slabs rather than basements, which puts supply and drain lines either under the floor or under concrete. We use bedding and burial techniques that minimize 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.

Proper plumbing installation is crucial for homes in Columbia, SC. Even with softer supply water in Columbia, a regular water heater flush still helps clear the sediment that settles in the bottom of the tank. Pipes in crawlspaces, exterior walls and unheated garages are the ones most likely to burst during a South Carolina cold snap, since many homes were built with little insulation around them.

Frequently Asked Questions About Plumbing Installation in Columbia
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.
While some minor fixture replacements might seem simple, complex installations like water heaters, gas lines, or repiping should always be handled by a licensed professional. Improper installation can lead to leaks, gas hazards, water damage, and code violations, which can be costly and dangerous. KBN Plumbing ensures safe, compliant work.
Common signs you might need new water lines in your Columbia home include consistently low water pressure, discolored water (especially reddish-brown), frequent leaks, or very old pipes (like galvanized steel). If your home is over 50 years old with original plumbing, it's often a good idea to consider repiping.
Yes, many plumbing installations in Columbia require permits to ensure compliance with local building codes. This includes new water heater installations, gas line additions or modifications, and major repiping projects. KBN Plumbing handles all necessary permitting and inspections as part of our service, making sure your installation is legal and safe.
You likely need a sump pump if your Columbia 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.
A water heater or softener install usually takes a few hours. Gas line runs and water line replacements can take a day, while whole-home repipes may take several days.
You should consider replacing your main water line if you experience consistently low water pressure, recurring leaks, discolored water, or an unusually high water bill that cannot be attributed to other issues. Older homes in Columbia often have aging galvanized or polybutylene pipes that are prone to failure, making replacement a smart investment.
KBN Plumbing stands behind our work with comprehensive warranties on both labor and installed materials. The specific warranty period varies by service and product, but we always make sure you receive manufacturer warranties on equipment. We are committed to resolving any issues that may arise post-installation.
