Abstract
A sewer cleaning device having an inlet nozzle assembly at one end for securing to a sewer jet and a sealed nozzle assembly oppositely disposed therefrom with water flowing from the sewer jet through each nozzle assembly and cables secured to a central housing between the nozzle assembly provides for a scraping and water jet action to clean a sewer pipe thoroughly.
Claims20
A device for cleaning a sewer capable of being attached to a sewer jet wherein:
- a. a housing having a water conveying tube and a central perforated cylinder is provided for said device;
- b. an inlet nozzle assembly is secured to a first end of said housing;
- c. a sealed nozzle assembly is secured to a second end of said housing and oppositely disposed from said inlet nozzle assembly;
