Sewer Nozzle Extensions: Yes or No?

It surprises me the number of us who do not consider the use of nozzle extensions as standard operating procedure (SOP) for jetting operations. The use of nozzle extensions, sometimes referred to as centralizers, offers three distinct benefits;

• keeping your nozzle centered in the pipe offers the nozzle a better chance to clean the entire pipe wall,
• the relatively inexpensive nozzle extension (about $70-$100 depending upon the style and your source of supply) can extend the life of your relatively expensive nozzle (this can range widely, between $100 for a very basic drilled steel radial nozzle, to expensive imports exceeding $3,000 retail) by a factor of many times,
• and finally, using an extension minimizes the risk that a nozzle can be deflected in a line and return in the direction of the operators, potentially causing serious injury and even death, so the use of the extension is actually a much desired safety enhancement.

Proofers (aka proofing skids) are a version of nozzle extension by their very design. However proofers add the additional benefit of providing the operator immediate feedback that a line is clear of obstruction over its entire length. Cities like Los Angeles and San Diego use these tools as a part of their SOP’s.

Recap: Nozzle extensions and proofers should be a part of you sewer and storm drain cleaning SOP because they offer:

• better sewer pipe cleaning
• extended sewer nozzle life
• enhanced operator safety
• confirmation the line is clear of obstructions (when using the proofer tool)
