Sorry for the terrible resolution. These are screen shots from a DVD. I would've just uploaded the video but I don't know how to rip it and convert to mpeg or where/how to upload.

The line pictured is 2" cast iron constricted in 1964. The cam and jetter were sent in from the stack for the laundry. The laundry runs about 30 feet to pick up the kitchen and then they run about 15ft and tie onto the main run of 3". I was called out after the customer had rented a ridgid k-380 from homer and could not get the line to fully accept the discharge from his laundry machine.

Jetting was done at 3500psi with a degreasing head at 4gpm. Afterwards (2 hours) about 90% of the cast iron scale was removed as well as grease and lint.

If someone wants to give me some pointers on how to get the video up, I'm game.

I'm posting the "before" pics first:

For those of you that aren't in the service side here's a little something about jetting. Not my video but fun to watch.

Ladies and gentlemen, I give you the chicken sandwich:

An explanation of jetting. The nozzle they are using is “the warthog”. It’s a great nozzle for large lines and it uses a viscous coupling in the rotating portion as a rotation limiter. The slow controlled rotation is what makes it work so well. Because the water jet passes over the pipe much more slowly it has more of a “slug effect” than if the jet was spinning at thousands of rpms. The high rpms tend to diffuse the energy of the jet. The down side to this nozzle is that it won’t make a bend in 4” pipe.

This is a pretty nice overview on drain pipe rehabilitation.
