Engineered Plumbing Solutions for Modern Construction Projects

Every new construction project depends on a well-designed and professionally installed plumbing system. Whether it's a single-family home, a multi-unit residential development, or a commercial facility, getting the plumbing right from the start is critical. Preferred Plumbing Solutions brings over 38 years of experience in delivering code-compliant, energy-efficient plumbing systems tailored specifically to new builds across Spirit Lake, Idaho, and surrounding areas, including Post Falls, Sandpoint, Spokane, Cheney, Moscow, Pullman, Rossland, and Castlegar.


Our licensed team collaborates directly with general contractors, developers, architects, and homeowners to ensure that every aspect of the plumbing plan aligns with the architectural layout, utility requirements, and long-term functionality of the property. From rough-ins to final fixture installations, we provide complete plumbing packages designed for durability and efficiency.

With deep familiarity with local soil conditions, climate patterns, and permitting processes in Kootenai County and surrounding areas, we bring a level of regional insight that national chains can’t offer. Our goal is to eliminate future issues by planning meticulously during the construction phase—reducing delays, avoiding rework, and increasing the overall value of the property. As local demand for housing and commercial space grows, our plumbing services ensure the infrastructure keeps pace with development throughout North Idaho.

Our New Construction Plumbing Services

Underground & Rough-In Plumbing

We install all under-slab and in-wall piping during early construction stages, ensuring optimal pipe placement and drainage. We coordinate closely with builders and contractors to match precise blueprints and avoid costly rework. Every connection is made with longevity and accessibility in mind.

Fixture Planning & Final Installation

From toilets and sinks to showers and water heaters, we install high-quality plumbing fixtures according to design plans. We ensure fixtures are code-compliant, water-efficient, and correctly aligned with architectural aesthetics. Our team also verifies each component for operational readiness at project closeout.

Water Line Installation & Pressure Testing

We lay main water lines and ensure pressure regulation systems are properly calibrated for residential or commercial water demand. We use only premium-grade piping and fittings, ensuring system durability. Our testing methods follow current code standards and project-specific performance benchmarks.

Drain, Waste & Vent (DWV) Systems

Proper venting and drainage are crucial in new construction. We design and install complete DWV systems that eliminate sewer gases, prevent blockages, and allow efficient waste removal through all fixture connections. Our crews follow strict slope and sizing guidelines to avoid costly future issues.

Gas Line Installation for Appliances

For new builds that require gas-powered appliances, we safely install gas lines with certified shut-off valves and pressure regulators. We handle hookups for furnaces, stoves, water heaters, and more. All gas plumbing is installed per safety code, with thorough leak testing performed before commissioning.

Utility Coordination & Final System Testing

We work with local utility providers to ensure proper hookups and final inspections. Before handing off the project, we conduct full-system tests to confirm functionality, flow, and leak-free operation throughout the structure. Our walkthroughs include documenting pressure ratings, fixture performance, and verifying that every component passes inspection.

Custom System Design for Optimal Performance

Professional plumbers collaborate with architects and builders to create plumbing systems tailored to the building’s blueprint and water usage needs. This precision helps avoid pressure drops, drainage issues, and inefficient layouts. From water mains to fixture placement, everything is planned to ensure smooth and consistent functionality.

Code Compliance and Inspection Readiness

Professionals stay updated on ever-changing plumbing codes and building regulations. Their expertise ensures installations pass all required inspections the first time, avoiding delays and rework. This also protects property owners from legal liabilities or penalties related to non-compliance.

High-Quality Materials and Installation Techniques

A professional plumber chooses the right materials for each application—be it copper for durability or PEX for flexibility. Skilled installation minimizes weak points and potential failure zones. As a result, the plumbing system delivers long-term reliability with reduced risk of leaks or water damage.

Energy and Water Efficiency Built In

Experts know how to integrate efficient technologies like tankless water heaters, pressure-balancing valves, and low-flow fixtures. These choices reduce water consumption and utility bills without compromising performance. In many cases, this also supports eco-conscious building certifications and resale value.

Future-Proofing and Expansion Readiness

Professional plumbing plans anticipate future needs by including strategic shut-offs, capped lines, and access points. This makes adding new appliances or expanding the system far easier down the road. Builders and owners gain flexibility without major demolition or costly retrofits.

Warranty Protection and Peace of Mind

Licensed plumbers provide warranties on both products and workmanship, offering valuable protection after project completion. This accountability ensures quick resolution if any issues arise. It also provides builders and buyers with confidence in the integrity of the plumbing system.
