How the ST49 Rotating Design Works

Rotating Cleaning Action

• Creates continuous rotational movement inside the pipe
• Increases agitation against pipe walls
• Helps remove stubborn buildup and deposits
• Improves overall cleaning effectiveness

Rear-Facing Jet Ports

• Propel the nozzle through the pipe
• Pull the hose deeper into the line
• Flush loosened debris toward the entry point
• Maintain efficient cleaning progression

The combination of rotation and rear-propulsion creates a powerful cleaning action that helps restore pipe performance and flow.

Typical Applications

• Sewer line cleaning
• Drain cleaning
• Grease removal
• Scale removal
• Pipe wall cleaning
• Residential plumbing maintenance
• Commercial drain cleaning
• Restaurant drain systems
• Preventative pipe maintenance
• Industrial drain cleaning

Performance Advantages

• Compact size improves maneuverability through bends and elbows
• Rotating action provides enhanced pipe wall cleaning
• Helps remove stubborn deposits more effectively than fixed nozzles
• Rear-facing jets provide self-propulsion through pipe systems
• Stainless steel construction resists corrosion and wear
• Compatible with flexible sewer hoses for improved navigation
• Reduces cleaning time in many applications
• Durable design for professional use
• Helps restore optimal pipe flow

Recommended Accessories

For maximum performance, this nozzle is commonly used with:

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

A foot-actuated valve can improve operator efficiency by allowing hands-free water 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 needed.
• Inspect jet ports for blockage or wear.
• Store in a clean, dry location.
• Replace if excessive wear or damage is observed.
