Guest House, ADU and Addition Plumbing in Tustin, 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 confirm 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 repair the yard when we are done.
Plumbing Rough-In Services in Tustin
The rough-in phase is the backbone of your new construction plumbing system. This involves installing all underground and in-wall piping before concrete is poured and walls are closed. We carefully lay out and connect all water supply, drain, and vent pipes according to architectural plans and local Tustin codes. Using high-quality PEX or copper piping, we ensure secure, leak-free connections that will serve your property for decades.
Underground and Under-Slab Plumbing in Tustin
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, damp 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.
Commercial New Construction Plumbing in Tustin, 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 extensive piping networks for office buildings, ensuring solid and efficient plumbing infrastructure across Tustin.
Gas Piping for New Homes in Tustin
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 runs at once. The system is pressure tested and inspected before the utility installs the meter.
Water Heater Installation for New Builds in Tustin
Selecting and installing the right water heater is crucial for any new construction. We provide professional installation of traditional tank-style and tankless water heaters, considering your property's hot water demands and energy efficiency goals. Our plumbers ensure correct sizing, venting, and gas or electrical connections, adhering to all safety regulations for new homes in Tustin.

Rough-In and Top-Out Plumbing in Tustin, 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 in doubt.

Frequently Asked Questions About New Construction Plumbing in Tustin
The cost of new construction plumbing in Tustin 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.
For new construction, we typically 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.
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.
Choosing a local plumber like FKM Plumbing for new construction in Tustin means working with professionals who understand local codes, soil conditions, and common building practices in Southern California. We have established relationships with local suppliers and inspectors, making for a smoother and more efficient project.
Intense sun breaks down exposed plastic pipe, sprinkler parts, and exterior fittings, so they wear out faster than indoor plumbing. On an occasional cold night, covering backflow preventers and outdoor valves is typically enough to avoid a break. We select materials and installation methods that can withstand local conditions, insulating pipes and burying lines at adequate depths where freezing is a risk. We also use materials that can handle thermal expansion and contraction, helping prevent leaks and bursts.
Yes, we can build a water softening system into your new construction plumbing design. Around Tustin, flushing the water heater yearly and cleaning aerators keeps scale buildup from cutting flow and efficiency. A softener loop is easy to add during the rough-in phase to protect your entire plumbing system and appliances from mineral buildup.
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 available for mains or exposed runs when you want it.
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 handle specific requests if you have a particular brand or style in mind, ensuring quality and availability for your new home.
