How the Rotating Design Works

Rotating Cleaning Action

• Continuously rotates during operation
• Creates additional agitation against pipe walls
• Helps remove stubborn deposits and buildup
• Improves overall cleaning effectiveness

Rear-Facing Propulsion Ports

• Pull the nozzle through the pipe system
• Flush loosened debris toward the entry point
• Reduce operator effort during cleaning
• Improve productivity and cleaning efficiency

The combination of rotation and propulsion allows for aggressive cleaning while maintaining smooth movement through drain and sewer systems.

Typical Applications

• Sewer line cleaning
• Drain cleaning
• Grease removal
• Scale removal
• Pipe wall cleaning
• Commercial plumbing maintenance
• Municipal sewer maintenance
• Industrial drain cleaning
• Preventative pipe maintenance
• Restaurant and food-service drain cleaning

Performance Advantages

• Rotating action cleans pipe walls more effectively than fixed nozzles
• Compact profile improves navigation through bends and elbows
• Rear jets provide self-propulsion through pipe systems
• Helps remove stubborn grease, sludge, and deposits
• Stainless steel construction resists corrosion and wear
• Compatible with many professional sewer jetting systems
• Suitable for higher-flow applications with #8.0 sizing
• Improves debris removal efficiency
• Long service life in demanding environments

Recommended Accessories

For optimal performance, the ST49 Rotating Sewer Nozzle is commonly used with:

• Flexible sewer jetting hoses
• Suttner sewer hose assemblies
• Foot-actuated control valves
• Professional sewer jetting equipment
• Pressure washer drain-cleaning systems

A foot-actuated valve can improve operator efficiency by allowing convenient water-flow control while reducing fatigue during extended cleaning operations.

Maintenance Recommendations

• Flush clean water through the nozzle after each use.
• Inspect rotating components regularly for smooth operation.
• Remove debris buildup as necessary.
• Inspect jet ports for blockage or wear.
• Check threads before installation.
• Store in a clean, dry location when not in use.
