Water Heater and Recirculation Installation in Madison, WI
New homes commonly use tank water heaters in the garage, basement or utility room, or tankless units on an exterior wall. We size the heater to your bathroom count and install gas or electric connections, venting, an expansion tank and drain pan where required. Many owners add a dedicated recirculation line during rough-in, which is far cheaper than retrofitting later. Hard water is common across much of Wisconsin, especially where supply comes from groundwater moving through limestone and dolomite. If treatment makes sense for your water, we suggest planning space for a softener or filter loop at the same time.

Gas Line Installation for New Homes in Madison
If your new home will use natural gas for heating, cooking, or water heating, HKV Plumbing provides safe and code-compliant gas line installation. This involves running new gas lines from the main supply to all gas appliances. Our licensed plumbers ensure all connections are secure and tested for leaks, adhering to strict safety protocols for gas work.
Gas Line Installation for New Construction in Madison, WI
Proper and safe gas line installation is a key component of new construction plumbing. Our certified technicians install new gas lines for appliances like furnaces, water heaters, stoves, and outdoor grills. We use approved materials and conduct rigorous leak testing to ensure the safety and integrity of your gas system, meeting all Wisconsin and local Madison codes.
New Construction Plumbing Cost Planning in Madison, WI
Plumbing for a typical new single-family home often 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 exactly where the money goes.
Sewer and Water Main Connections in Madison, WI
Connecting your new home to the municipal sewer and water mains is a key step in new construction plumbing. HKV Plumbing handles all aspects of these connections, including excavation, trenching, pipe laying, and backfilling. We ensure proper grading and sealing to prevent future leaks or blockages. Freeze and thaw cycles shift the ground each year, which can crack older clay and cast iron sewer laterals.
Rough-In Plumbing Services in Madison
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 meticulously plan and execute the rough-in, using high-quality fittings and ensuring all pipes are properly secured and leak-tested before inspection.

HKV 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 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 Wisconsin climate.

We also plumb small commercial buildouts, offices, retail suites and multifamily projects.

We read commercial plans, coordinate submittals and keep the general contractor informed through each inspection. Our crews scale up so plumbing never becomes the bottleneck on your schedule.
