Fixture Installation and Finishing in Simi Valley, CA
Once the rough-in is complete and walls are up, FKM Plumbing handles the final installation of all plumbing fixtures.

We ensure everything is properly aligned, sealed, and fully functional, providing a polished finish to your new home's plumbing system.

Preventing Common Southern California Plumbing Issues in New Builds in Simi Valley, CA
New construction in Southern California must account for local conditions. 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. We focus on installations that resist shifting foundations and soil movement, which can stress pipes. Hard water shortens the life of tankless units, valves, and appliances, which is why many homes in Southern California add softeners or scale filters. We recommend suitable piping materials and treatment options to minimize scale buildup over time, so your new home's plumbing lasts for decades.
Gas Line Installation for New Construction in Simi Valley, CA
Proper and safe gas line installation is a critical component of new construction plumbing. Our trained technicians install new gas lines for appliances like furnaces, water heaters, stoves, and outdoor grills. We use approved materials and conduct rigorous leak testing to ensure the safety and integrity of your gas system, meeting all Southern California and local Simi Valley codes.
Fixture Installation and Trim-Out in Simi Valley, 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 ensure 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.
Underground and Under-Slab Plumbing in Simi Valley
The underground phase sets the drain, waste and vent layout that every fixture in the house will rely 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 visible for the inspector before your concrete contractor pours.
Residential New Build Plumbing in Simi Valley
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. Hard water shortens the life of tankless units, valves, and appliances, which is why many homes in Southern California install softeners or scale filters. Our process includes meticulous planning to prevent future slab leaks or drainage problems tied to the soil under your lot.
Permits and Inspections for New Plumbing in Simi Valley, CA
FKM Plumbing handles all required plumbing permits and coordinates with local Simi Valley inspectors throughout the new construction process. We ensure every phase of the plumbing installation, from rough-in to final trim-out, passes inspection. Our knowledge of local regulations means your project stays compliant, avoiding delays and ensuring the long-term validity of your plumbing system.

Sewer and Drainage Systems in New Builds in Simi Valley
A dependable sewer and drainage system is essential for any new property. We design and install complete sewer lines, septic systems, and storm drains, making sure of 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 durable PVC piping and careful bedding to prevent future blockages or pipe damage.

Frequently Asked Questions About New Construction Plumbing in Simi Valley
The cost of new construction plumbing in Simi Valley varies widely 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 run higher.
We install a wide range of trusted plumbing fixture brands based on your preferences and budget, including Kohler, Moen, Delta, American Standard, and Toto. We can also accommodate specific requests if you have a particular brand or style in mind, ensuring quality and availability for your new home.
Plumbing is usually covered under the general building permit, but we handle the plumbing inspections and any separate plumbing or gas permits your jurisdiction requires. We hold the licenses Southern California requires for plumbing work. Our team schedules each inspection and walks with the inspector on site.
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.
Yes, we can integrate a water softening system into your new construction plumbing design. Hard water shortens the life of tankless units, valves, and appliances, which is why many homes in Southern California install softeners or scale filters. A softener loop is easy to add during the rough-in phase to protect your entire plumbing system and appliances from mineral buildup.
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. 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.
FKM Plumbing stands behind our new construction plumbing work with a comprehensive warranty on both labor and materials. Specific warranty terms vary by project and components and are spelled out in your contract, and we honor manufacturer warranties on all installed parts and fixtures. Your satisfaction and peace of mind are our focus.
