Drain & Sewer Cleaning

Advanced Techniques to Eliminate Clogs and Backups Recurring clogs, slow drains, and unpleasant odors are often symptoms of deeper issues in your sewer line. Flynn Plumbing & Mechanical LLC offers superior drain and sewer cleaning services in the Federal Way and surrounding areas. We begin with detailed video camera inspection to precisely locate the obstruction (e.g., roots, grease, debris). We then utilize professional-grade solutions like powerful snaking or high-pressure hydro-jetting to completely clear the line, ensuring a long-term flow restoration that chemical cleaners cannot achieve.
