Commercial Drain Cleaning & Hydro-Jetting in Corona
Commercial drains handle significantly higher volumes and different types of waste than residential ones, leading to more frequent and stubborn clogs. Our services include powerful hydro-jetting, which uses high-pressure water streams to scour pipe interiors, removing grease, sludge, and debris that build up in commercial kitchens and restrooms. This method is highly effective for maintaining the large diameter pipes typical in commercial settings and preventing costly backups in Corona, CA. We service all types of commercial properties, from restaurants to retail stores.
Backflow Testing and Repair in Corona
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 remain in compliance.
Slab Leak Detection & Repair for Businesses in Corona
Slab leaks can be especially damaging for commercial buildings, especially those built on concrete slab foundations. Earthquakes are a constant consideration in Southern California, and seismic straps and flexible connectors help keep water and gas lines secure during shaking. These leaks, often caused by shifting soil or corrosive water, can undermine foundations, lead to mold growth, and cause significant water waste. Our technicians use modern acoustic and thermal imaging equipment to pinpoint slab leaks without invasive demolition. Once located, we provide practical repair solutions, often involving re-routing or pipe repair, to protect your commercial property and prevent costly structural damage in Corona.
Grease Trap Installation & Cleaning in Corona
Restaurants and food service establishments in Corona rely on working grease traps to prevent fats, oils, and grease (FOG) from entering the sewer system. FKM Plumbing offers professional grease trap installation, repair, and regular cleaning services. We ensure your grease trap is correctly sized for your business's needs and maintained to comply with local FOG regulations, preventing costly blockages and potential fines from the city.
Grease Trap and Interceptor Service in Corona, CA
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 feeding 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 dinner rush.
Commercial Water Heaters and Boilers in Corona, CA
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. Around Corona, flushing the water heater yearly and cleaning aerators keeps scale buildup from cutting flow and efficiency. Mineral scale can build up in these systems quickly, so we offer descaling and flushing on a schedule. We also install mixing valves to deliver safe temperatures at handwashing sinks.

Protecting your potable water supply from contamination is critical for any commercial property in Corona.
