Commercial Drain Cleaning & Hydro-Jetting in Nitro
Commercial drains handle far 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 very effective for maintaining the large diameter pipes typical in commercial settings and preventing costly backups in Nitro, WV. We service all types of commercial properties, from restaurants to retail stores.
Grease Trap and Interceptor Service in Nitro, WV
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.
Commercial Restroom Plumbing in Nitro
Busy restrooms take a beating, and a broken flushometer or leaking urinal annoys customers. We repair and replace Sloan and Zurn flush valves, sensor faucets, wall-hung toilets and carriers. We also install ADA-compliant fixtures and grab bar backing during upgrades. Quick repairs keep your facilities clean and open.
Backflow Prevention Device Services in Nitro
Backflow prevention devices are essential for protecting the public water supply from contamination, a serious concern for commercial properties in Nitro.

Our certified plumbers provide complete testing, repair, and installation of backflow preventers, helping your business stay compliant and safe. We handle all types, including reduced pressure zone (RPZ) assemblies and double check valve assemblies, which are common in commercial and industrial applications. Keeping these devices in good working order is a non-negotiable safety measure.
Commercial Water Heater Repair & Installation in Nitro, WV
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, making sure your business has a consistent supply of hot water. Whether it's a gas, electric, or tankless system, our technicians are trained in diagnosing issues like pilot light failures, heating element malfunctions, or pressure relief valve problems specific to high-demand commercial use in Nitro.
