Commercial and Multifamily New Construction in Walnut Creek
We also plumb small commercial buildouts, offices, retail suites and multifamily projects.

Residential New Build Plumbing in Walnut Creek
For new homes, our residential new construction plumbing includes the complete installation of water supply lines, drain waste vent systems, and gas lines. We confirm proper sizing and pressure for all fixtures, from showers to kitchen sinks, while accounting for local water quality and potential foundation movement. Water hardness in Northern California varies a lot by source, with snowmelt-fed systems running soft and many inland groundwater systems running hard. Our process includes careful planning to prevent future slab leaks or drainage issues tied to the soil under your lot.
Sewer and Water Main Connections in Walnut Creek, 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. Earthquakes and hillside soil movement are real risks in Northern California, so flexible connections and seismic straps help protect plumbing from sudden movement.
Commercial New Construction Plumbing in Walnut Creek, CA
We offer complete 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 large grease traps for restaurants to long piping networks for office buildings, ensuring robust and efficient plumbing infrastructure across Walnut Creek.
Gas Piping for New Homes in Walnut Creek
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. We calculate total BTU load and pipe length so every appliance gets enough pressure even when everything is running together. The system is pressure tested and inspected before the utility sets the meter.
Final Trim and Fixture Setting in Walnut Creek
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.
Rough-In Plumbing Services in Walnut Creek
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 carefully plan and execute the rough-in, using high-quality fittings and ensuring all pipes are properly secured and leak-tested before inspection.

Gas Line Installation for New Homes in Walnut Creek
If your new home will use natural gas for heating, cooking, or water heating, FBL 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.
