Hydrojetting
High-Pressure CleaningWhen snaking isn’t enough, hydrojetting is the most effective method for clearing stubborn grease, scale, and root intrusion from drain and sewer lines. Using water at up to 4,000 PSI, hydrojetting scours pipe walls clean and restores full pipe capacity, ideal for commercial properties and recurring residential blockages.
