Duct Rods & Sewer Sondes – push rods, sondes & accessories

Push rods position the sonde at the target point; the sonde emits a locating signal that a surface receiver tracks with depth readout. Choose rods with suitable diameter/bend radius and sondes with the right frequency for your network.

  • Push/traceable rods: durable rods with connection options for tight bends and long runs
  • Sonde frequencies: common 512 Hz for sewer/non-metallic lines; alternate bands for specific environments
  • Adapters & springs: M-thread (e.g. M8/M10) for flexible, shock-absorbing coupling
  • Power & spares: batteries and accessories to keep kits field-ready

Selection guide

  • Task: Route tracing, blockage pinpointing, verifying branches/service laterals.
  • Rod & length: Match rod diameter/length to pipe size, bend radius and distance.
  • Frequency plan: Use 512 Hz as a sewer standard; switch bands if interference occurs.
  • Interfaces: Choose M-thread adapters (e.g. M8/M10) to fit your sonde and reel.

Field tip

Cross-check the route and confirm depth on the receiver. If signals are noisy, change frequency or adjust the coupling point.
