Sewer and Drainage Systems in New Builds in Green Bay

A reliable sewer and drainage system is essential for any new property. We design and install complete sewer lines, septic systems, and storm drains, making sure of proper grading and connection to municipal services or on-site treatment systems. Full basements are standard in Wisconsin homes, and sump pumps are common where clay or high groundwater holds water near the foundation. We account for soil movement on your lot, using durable PVC piping and careful bedding to prevent future blockages or pipe damage.

Water Heater and Recirculation Installation in Green Bay, WI

New homes often 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 much less expensive 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 recommend planning space for a softener or filter loop at the same time.

Rough-In and Top-Out Plumbing in Green Bay, WI

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.

Plumbing Rough-In Services in Green Bay

The rough-in phase is the foundation of your new construction plumbing system. This involves installing all underground and in-wall piping before concrete is poured and walls are closed. We carefully lay out and connect all water supply, drain, and vent pipes according to architectural plans and local Green Bay codes. Using durable PEX or copper piping, we ensure secure, leak-free connections that will serve your property for decades.

Gas Line Installation for New Homes in Green Bay

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 equipment. Our licensed plumbers ensure all connections are secure and tested for leaks, adhering to strict safety protocols for gas work.

Fixture Installation and Trim-Out in Green Bay, WI

Once the rough-in is complete and walls are up, our team returns for fixture installation and trim-out. This includes connecting sinks, toilets, bathtubs, showers, dishwashers, and water heaters. We make sure all fixtures are properly seated, sealed, and functional, providing a professional finish to your new construction plumbing. We work with many brands like Moen, Kohler, and American Standard to match your design specifications.

Guest House, ADU and Addition Plumbing in Green Bay, WI

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 confirm there is enough fall to the new building. Supply lines can be branched from the main house or run as a separate service, based on distance and pressure. We also handle the trenching between structures and repair the yard when we are done.

Final Trim and Fixture Setting in Green Bay

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.
