Gas Piping for New Homes in Rapid City
We size and install gas piping for ranges, water heaters, furnaces, fireplaces, pool heaters and outdoor kitchens.

Guest House, ADU and Addition Plumbing in Rapid City, SD
Guest houses and additions need plumbing that ties into the existing house without overloading old drain lines. We locate the existing sewer, check its condition with a camera and verify there is enough fall to the new building. Supply lines can be branched from the main house or run as a separate service, depending on distance and pressure. We also handle the trenching between structures and repair the yard when we are done.
Sewer and Drainage Systems in New Builds in Rapid City
A reliable sewer and drainage system is essential for any new property. We design and install complete sewer lines, septic systems, and storm drains, ensuring proper grading and connection to municipal services or on-site treatment systems.

We account for soil movement on your lot, using durable PVC piping and careful bedding to prevent future blockages or pipe damage.

For new homes, our residential new construction plumbing includes the complete installation of water supply lines, drain waste vent systems, and gas lines.

Our process includes meticulous planning to prevent future slab leaks or drainage issues tied to the soil under your lot.

Yes, we can integrate a water softening system into your new construction plumbing design. Many rural homes in South Dakota draw from private wells or rural water systems, and a water test is the best way to know what comes out of the tap. A softener loop is easy to add during the rough-in phase to protect your entire plumbing system and appliances from mineral buildup.
Basements are common in South Dakota homes, which puts water heaters, softeners and main drains below grade where sump pumps often play a role. Soil that shifts and swells with moisture changes can put stress on underground plumbing. We reduce this by using flexible piping materials and proper bedding techniques to help protect against pipe damage from soil movement.
We can run a dedicated return line during rough-in so hot water reaches distant bathrooms in seconds. A dedicated line works better than retrofit crossover valves and adds roughly $800 to $2,000 depending on layout. It also saves the water that would otherwise run down the drain while you wait for hot water.
For new construction, we usually use PEX, or cross-linked polyethylene, for water supply lines due to its flexibility, durability, and resistance to corrosion. For drain, waste, and vent systems, we primarily use PVC piping because it's strong, lightweight, and cost-effective.
