Underground and Under-Slab Plumbing in Lenexa

The underground phase sets the drain, waste and vent layout that every fixture in the house will depend on. We trench, bed and slope PVC or ABS drain lines at a minimum quarter inch per foot and protect every pipe that passes through the slab or foundation with sleeves. Slab leaks and broken sewer laterals are common results of shifting clay, especially after long dry spells followed by heavy rain. We compact bedding carefully and avoid rigid points that could stress the pipe as the ground moves. Each line is water tested and left exposed for the inspector before your concrete contractor pours.

Fixture Installation and Finishing in Lenexa, KS

Once the rough-in is complete and walls are up, KRV Plumbing handles the final installation of all plumbing fixtures. This includes sinks, toilets, showers, bathtubs, dishwashers, and washing machines. We ensure everything is perfectly aligned, sealed, and fully functional, providing a polished finish to your new home's plumbing system.

New Construction Plumbing Cost Planning in Lenexa, KS

Plumbing for a typical new single-family home usually runs about 4 to 8 percent of total build cost, depending on fixture count and finish level. A modest three-bedroom home often lands between $12,000 and $25,000, while custom homes with multiple suites and outdoor kitchens run higher. Choices like a manifold PEX system, a recirculation loop and fixture grade affect the price the most. We break the bid out by phase so you can see clearly where the money goes.

Sewer and Drainage Systems in New Builds in Lenexa

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. Slab leaks and broken sewer laterals are common results of shifting clay, especially after long dry spells followed by heavy rain. We account for soil movement on your lot, using tough PVC piping and careful bedding to prevent future blockages or pipe damage.

Gas Piping for New Homes in Lenexa

We size and install gas piping for ranges, water heaters, furnaces, fireplaces, pool heaters and outdoor kitchens. Black iron and CSST systems are both options, and CSST is bonded per manufacturer and code requirements. We calculate total BTU load and pipe length so every appliance gets enough pressure even when everything runs at once. The system is pressure tested and inspected before the utility installs the meter.

Residential New Construction Plumbing in Lenexa

KRV Plumbing focuses on 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 tailored 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 Kansas' climate.

Final Trim and Fixture Setting in Lenexa

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 verify the system drains and vents properly under load.

Rough-In and Top-Out Plumbing in Lenexa, KS

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 goes on. A full pressure test is held for inspection so nothing hidden in the walls is ever a question.
