I have a Harben jetter, 14gpm at 4000, yesterday I had to give up on a job, 15 meters of 110mm (4.5 inch) tube that the builders had left full of heavy sediments, I could only enter from upstream. In the end the builders agreed to replace the blocked section. I am fairly new to the business and I have always had problems with clearing heavy silt, I just seem to move it up and down the pipe, anyone got any advice?
No announcement yet.
