Cleaning dry hard set cement paste from 8" cast iron paste pipes using various nozzles to achieve the best outcome.
The Root Ranger Double Ended Nozzle came out on top...
Com: Thomas : i don't understand how that cement got in the line??
I don't know if i would have went through all the work and expense of jetting it, maybe just replace it???
Com: Sam aguirre : I worked on a rig and we would’ve love to have had this little gem, sorry to say all we had was the single drill head
Com: Timoty rossa : For those of you who don't know, pipe jetting is common practice.
It's the heavy alternative to running a cable (snake) through a pipe to clear a blockage.
Now as far as the concrete in the line,
1. I believe this video is a demo for this Head.
2. There will be times rocks a inert materials find their way into drains ,
holes in caved in or compromised (clay or cast iron) drain/grey water lines.
