Sewer and Water Main Connections in Fontana, CA
Connecting your new home to the municipal sewer and water mains is a key step in new construction plumbing. FKM 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. Expansive clay and hillside soils can shift over time, putting stress on slab plumbing and separating older sewer joints.

Gas Line Installation for New Construction in Fontana, CA
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 perform rigorous leak testing to ensure the safety and integrity of your gas system, meeting all Southern California and local Fontana codes.
Fixture Installation and Finishing in Fontana, CA
Once the rough-in is complete and walls are up, FKM 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.
Rough-In and Top-Out Plumbing in Fontana, CA
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.
Rough-In Plumbing Services in Fontana
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 durable fittings and ensuring all pipes are properly secured and leak-tested before inspection.
Fixture Installation and Trim-Out in Fontana, CA
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.
Water Heater and Recirculation Installation in Fontana, CA
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. Municipal water across much of Southern California is hard, leaving white scale on faucets, showerheads, and inside water heater tanks. If treatment makes sense for your water, we recommend planning space for a softener or filter loop at the same time.

FKM 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 Southern California climate.
