Gas Piping for New Homes in Great Falls
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.

The system is pressure tested and inspected before the utility installs the meter.

Gas Line Installation for New Homes in Great Falls
If your new home will use natural gas for heating, cooking, or water heating, DFV 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 confirm all connections are secure and tested for leaks, adhering to strict safety protocols for gas work.
Fixture Installation and Finishing in Great Falls, MT
Once the rough-in is complete and walls are up, DFV Plumbing handles the final installation of all plumbing fixtures. This includes sinks, toilets, showers, bathtubs, dishwashers, and washing machines. We ensure everything is properly aligned, sealed, and fully functional, providing a polished finish to your new home's plumbing system.
Water Heater and Recirculation Installation in Great Falls, MT
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 far cheaper than retrofitting later. Water across much of Montana is moderately hard to hard, especially from wells, so scale buildup in water heaters and faucets is common. If treatment makes sense for your water, we recommend planning space for a softener or filter loop at the same time.
Plumbing Rough-In Services in Great Falls
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 precisely lay out and connect all water supply, drain, and vent pipes according to architectural plans and local Great Falls codes. Using high-quality PEX or copper piping, we ensure secure, leak-free connections that will serve your property for decades.
Sewer and Water Main Connections in Great Falls, MT
Connecting your new home to the municipal sewer and water mains is a critical step in new construction plumbing. DFV 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. Both basements and crawlspaces are common, and frost heave can damage shallow lines that were not buried deep enough.

Water Heater Installation for New Builds in Great Falls
Selecting and installing the right water heater is crucial 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.
