We submit the results to your water provider so you stay in compliance.
Commercial Drain Cleaning & Hydro-Jetting in Dover
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 accumulate 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 Dover, DE. We service all types of commercial properties, from restaurants to retail stores.
Grease Trap and Interceptor Service in Dover, DE
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 the dinner rush.
