Commercial Plumbing That Keeps Your Building Running

Commercial plumbing has to keep up with daily use, inspections, and tight schedules. Preferred Plumbing Solutions builds and services systems for businesses in Spirit Lake, Coeur d'Alene, Post Falls, Sandpoint, and Spokane.

We work on retail centers, warehouses, office buildings, restaurants, and more. Every job gets planned around how your place actually operates. We know North Idaho winters, freeze-ups, and the water quality quirks that hit rural properties.

We stay code-compliant, keep energy waste down, and coordinate with general contractors, property managers, and owners so the job stays on track. From design through final inspection, we handle the plumbing side.

How we can help.

Plumbing System Design & Planning

We work with architects and project leads to design systems that pass code, run efficiently, and match how the building will be used. Fixture counts, pipe sizing, demand, and room to grow later all get worked out up front.

Commercial Water Heater Installation

We install high-capacity tanks and tankless units for hotels, medical offices, and other high-demand sites. We look at your real usage and recommend equipment that balances cost with performance.

Backflow Prevention & Testing

Many commercial sites need certified backflow protection. We install and test assemblies to keep potable water safe, and we handle annual testing, certifications, and repairs.

Sewer & Drain Infrastructure

We build and repair drain systems, stormwater lines, and sewer runs. Camera work and solid routing help cut down on clogs and backups later.

Grease Trap Installation & Maintenance

A must for restaurants and food service. We install new traps and keep them on a schedule so you avoid clogs, fines, and messy shutdowns.

Commercial Fixture & Appliance Installations

We install commercial toilets, faucets, urinals, kitchen sinks, dishwashers, and disposals built for heavy use. Every install gets pressure testing, leak checks, and proper sealing.

Built around the way you work.

Business plumbing needs a plan for access, use, and the people who depend on it.
