Sewer and Drainage Systems in New Builds in Ontario

A dependable 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. Most homes in Southern California sit on concrete slabs, so slab leaks often show up as warm floors, wet carpet, or an unexplained jump in the water bill. We account for soil movement on your lot, using tough PVC piping and careful bedding to prevent future blockages or pipe damage.

Sewer and Water Main Connections in Ontario, CA

Connecting your new home to the municipal sewer and water mains is a critical step in new construction plumbing. FKM Plumbing handles all aspects of these connections, including excavation, trenching, pipe laying, and backfilling. We provide proper grading and sealing to prevent future leaks or blockages. Most homes in Southern California sit on concrete slabs, so slab leaks often show up as warm floors, damp carpet, or an unexplained jump in the water bill.

Gas Line Installation for New Homes in Ontario

If your new home will use natural gas for heating, cooking, or water heating, FKM 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.

Final Trim and Fixture Setting in Ontario

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.

Commercial and Multifamily New Construction in Ontario

We also plumb small commercial buildouts, offices, retail suites and multifamily projects. These jobs frequently require grease interceptors, backflow assemblies, commercial water heaters and ADA compliant fixtures. We read commercial plans, coordinate submittals and keep the general contractor updated through each inspection. Our crews scale up so plumbing never becomes the bottleneck on your project.

Underground and Under-Slab Plumbing in Ontario

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. Most homes in Southern California sit on concrete slabs, so slab leaks often show up as warm floors, wet carpet, or an unexplained jump in the water bill. 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.

New Construction Plumbing Cost Planning in Ontario, CA

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 clearly where the money goes.
