Commercial New Construction Plumbing in Petaluma, CA
We offer comprehensive commercial new construction plumbing for businesses, multi-family units, and industrial properties. This includes larger capacity water heaters, backflow prevention devices, specialized drainage systems, and compliance with commercial building codes. Our team handles everything from complex grease traps for restaurants to long piping networks for office buildings, ensuring robust and efficient plumbing infrastructure across Petaluma.
Rough-In and Top-Out Plumbing in Petaluma, 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 typically 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 in doubt.
Sewer and Water Main Connections in Petaluma, CA
Connecting your new home to the municipal sewer and water mains is a key step in new construction plumbing. FBL 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 soils are common across Northern California, and seasonal swelling and shrinking can crack slabs and buried sewer laterals.
Guest House, ADU and Addition Plumbing in Petaluma, CA
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 verify 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 restore the yard when we are done.
Underground and Under-Slab Plumbing in Petaluma
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. Expansive clay soils are common across Northern California, and seasonal swelling and shrinking can shift slabs and buried sewer laterals. 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.
Rough-In Plumbing Services in Petaluma
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.

Residential New Build Plumbing in Petaluma
For new homes, our residential new construction plumbing includes the complete installation of water supply lines, drain waste vent systems, and gas lines. We ensure proper sizing and pressure for all fixtures, from showers to kitchen sinks, while accounting for local water quality and potential foundation movement. Rural properties around Petaluma often rely on private wells, which may need filtration for iron, sediment, or other minerals. Our process includes meticulous planning to prevent future slab leaks or drainage problems tied to the soil under your lot.

Frequently Asked Questions About New Construction Plumbing in Petaluma
The cost of new construction plumbing in Petaluma varies a lot based on the size and complexity of the project, number of bathrooms, and fixture choices. For a standard 3-bedroom, 2-bathroom home, rough-in and finish plumbing can range from $10,000 to $25,000. Commercial projects or luxury homes with advanced systems will be higher.
Yes, absolutely. All new construction plumbing in Petaluma, CA requires permits from the local building department. This ensures the work meets local codes and standards. FBL Plumbing handles all necessary permit applications and ensures our work passes all required inspections, taking that burden off your shoulders.
Some jurisdictions allow owner-builders to do their own plumbing on a home they will live in, but the work still has to pass every inspection. Under-slab and gas work are the hardest to get right and the most expensive to fix later. Many owner-builders hire us for those phases and finish easier tasks themselves.
Yes, our experienced team can assist with the plumbing design and layout for your new home. We work with your architectural plans to optimize water flow, drain efficiency, and fixture placement. Our goal is to create a functional, efficient, and code-compliant plumbing system that meets your family's needs.
For new construction, we usually use PEX, or cross-linked polyethylene, for water supply lines due to its flexibility, durability, and resistance to corrosion. For drain, waste, and vent systems, we primarily use PVC piping because it's strong, lightweight, and cost-effective.
Expansive clay soils are common across Northern California, and seasonal swelling and shrinking can crack slabs and buried sewer laterals. Soil that shifts and swells with moisture changes can put stress on underground plumbing. We mitigate this by using flexible piping materials and proper bedding techniques to help protect against pipe damage from soil movement.
Common challenges in new construction plumbing include coordinating with other trades, working around site-specific conditions like rocky soil or foundation types, and ensuring strict adherence to evolving building codes. Our experienced team in Petaluma is adept at navigating these complexities.
We typically use PEX-A for water supply because it handles heat and resists the scale and pinhole problems copper can develop with aggressive or hard water. Drains are usually PVC or ABS, depending on local code and builder preference. Copper is an option for mains or exposed runs when you want it.
