Apparatus for cleaning pipes having pumping and vacuuming capability
An apparatus for cleaning waste collection systems of solid materials. The apparatus is capable of cleaning waste systems in two known ways. First, a pumping method uses normal and injected water flow to suspend the solids in a slurry.

Second, a vacuum system may be used to move the slurry from the waste system to the waste container. The vacuum system creates a negative pressure differential, causing material to be pulled through a vacuum tube and into the waste container. When the container becomes substantially full of solid particles, it may be emptied at a dumpsite. |

The elasticised sectors (3) are designed portions which create ornamental figures or banding with specific compression which can provide support, contribute to the stimulation of blood circulation, reduce fatigue, and render movement safer and more supported, when properly positioned and sized. |
