Commercial Grease Trap Services in Spokane, WA
Restaurants and food service establishments in Spokane are required by law to maintain functional grease traps to prevent fats, oils, and greases (FOG) from entering the sewer system. FHN Plumbing offers complete grease trap cleaning, repair, and installation services. Regular cleaning is essential to prevent blockages and ensure compliance with local health codes. We also diagnose problems like foul odors, slow drainage, or trap overflow, making sure your kitchen operations run smoothly and avoid costly fines and environmental hazards.

Backflow Testing and Repair in Spokane
Most water providers require annual testing of backflow prevention assemblies on commercial properties. We test reduced pressure zone, double check and pressure vacuum breaker assemblies with calibrated gauges. When a device fails, we rebuild it with manufacturer kits from Watts, Wilkins or Febco. We submit the results to your water provider so you stay in compliance.
Commercial Water Heater Repair & Installation in Spokane, WA
Commercial water heaters are often larger, more complex, and operate under greater stress than residential units, often requiring specialized repair and maintenance. We service all major brands including A.O. Smith, Rheem, and Bradford White commercial models, ensuring your business has a consistent supply of hot water. Whether it's a gas, electric, or tankless system, our technicians are skilled in diagnosing issues like pilot light failures, heating element malfunctions, or pressure relief valve problems specific to high-demand commercial use in Spokane. Proper sizing and installation are crucial for efficiency and longevity.
Commercial Water Heaters and Boilers in Spokane, WA
Commercial kitchens, gyms and multi-family buildings need large amounts of hot water. We service and install high-input tank water heaters, tankless racks and boiler-fed systems with storage tanks. Soft water can be slightly corrosive to copper over time, which sometimes shows up as pinhole leaks in older supply lines. Mineral scale can build up in these systems fast, so we offer descaling and flushing on a schedule. We also install mixing valves to deliver safe temperatures at hand-washing sinks.
Grease Trap and Interceptor Service in Spokane, WA
Restaurants and food service sites must keep grease out of the public sewer. We inspect and service grease traps and interceptors, replace baffles and clear the lines leading to them. Hydro jetting removes hardened grease from kitchen drains that cables cannot clear. Regular service helps you pass health inspections and avoid sewer backups during the dinner rush.
