Guest House, ADU and Addition Plumbing in Irvine, 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, depending on distance and pressure. We also handle the trenching between structures and restore the yard when we are done.

Plumbing Rough-In Services in Irvine
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 Irvine codes. Using high-quality PEX or copper piping, we ensure secure, leak-free connections that will serve your property for decades.
Gas Piping for New Homes in Irvine
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 sets the meter.
Gas Line Installation for New Homes in Irvine
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 equipment. Our licensed plumbers ensure all connections are secure and tested for leaks, adhering to strict safety protocols for gas work.
Residential New Build Plumbing in Irvine
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. Hard water shortens the life of tankless units, valves, and appliances, which is why many homes in Southern California add softeners or scale filters. Our process includes meticulous planning to prevent future slab leaks or drainage issues tied to the soil under your lot.
Fixture Installation and Trim-Out in Irvine, 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 make sure all fixtures are properly seated, sealed, and functional, providing a professional finish to your new construction plumbing. We work with various brands like Moen, Kohler, and American Standard to match your design specifications.
Gas Line Installation for New Construction in Irvine, 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 Irvine codes.

Water Heater and Recirculation Installation in Irvine, CA
New homes often use tank water heaters in the garage, basement or utility room, or tankless units on an exterior wall. We size the heater to your bathroom count and install gas or electric connections, venting, an expansion tank and drain pan where required. Many owners add a dedicated recirculation line during rough-in, which is much less expensive than retrofitting later. Hard water shortens the life of tankless units, valves, and appliances, which is why many homes in Southern California install softeners or scale filters. If treatment makes sense for your water, we suggest planning space for a softener or filter loop at the same time.

In many homes, yes. Hard water shortens the life of tankless units, valves, and appliances, which is why many homes in Southern California add softeners or scale filters. A softener loop costs a few hundred dollars during construction and much more to retrofit later. The loop lets you add a softener or filtration system any time without opening up walls.
Yes, absolutely. All new construction plumbing in Irvine, CA requires permits from the local building department. This ensures the work meets local codes and standards. FKM Plumbing handles all necessary permit applications and ensures our work passes all required inspections, taking that task 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 simpler tasks themselves.
Hot inland summers push water heaters and pool plumbing hard, while coastal salt air can corrode exposed metal fittings. On an occasional cold night, covering backflow preventers and outdoor valves is usually all it takes to avoid a break. We select materials and installation methods that can handle 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.
