Rough-In and Top-Out Plumbing in Hilton Head Island, SC
Once framing is up, we run supply and vent lines through the walls and attic and set every stub-out for sinks, tubs, showers and appliances. We usually install PEX-A with a central manifold so each fixture gets its own line and shutoff. Shower valves are set at the heights you choose, and tub sets are installed and protected before the drywall is hung. A full pressure test is held for inspection so nothing hidden in the walls is ever a question.

Water Heater Installation for New Builds in Hilton Head Island
Selecting and installing the right water heater is essential for any new construction. We provide expert installation of traditional tank-style and tankless water heaters, considering your property's hot water demands and energy efficiency goals. Our plumbers confirm correct sizing, venting, and gas or electrical connections, adhering to all safety regulations for new homes in Hilton Head Island.
Rough-In Plumbing Services in Hilton Head Island
The rough-in phase is where the core plumbing system is installed within the walls, floors, and ceilings before drywall. This includes all supply lines, drain lines, and vent piping for every fixture. Our plumbers carefully plan and execute the rough-in, using durable fittings and ensuring all pipes are properly secured and leak-tested before inspection.
Sewer and Water Main Connections in Hilton Head Island, SC
Connecting your new home to the municipal sewer and water mains is a key step in new construction plumbing. KBN Plumbing handles all aspects of these connections, including excavation, trenching, pipe laying, and backfilling. We provide proper grading and sealing to prevent future leaks or blockages. 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.

KBN Plumbing specializes in complete plumbing system installations for new residential homes. This includes designing the layout, installing all water supply lines, drain lines, and vent piping. We work closely with homeowners and builders to ensure the plumbing system is matched to the home's specifications and future needs, using materials like PEX and copper for supply lines and PVC for drains, chosen for durability in South Carolina climate.

Final Trim and Fixture Setting in Hilton Head Island
At trim we install toilets, faucets, garbage disposals, dishwashers, ice maker boxes and laundry connections. We work with fixtures from Moen, Delta, Kohler, American Standard and the other brands builders often choose, or with owner-supplied fixtures. Every fixture is checked for flow, drainage and leaks, and angle stops are set straight and tight. We finish by running every fixture at once to confirm the system drains and vents properly under load.

Fixture Installation and Finishing in Hilton Head Island, SC
Once the rough-in is complete and walls are up, KBN Plumbing handles the final installation of all plumbing fixtures.
