Has anybody ever used one of these or seen it done? Pulls new pipe through the existing pipe by cutting it out of the way.

Haven't seen it in person, but saw it done on one of those home improvement shows. They were replacing clay drain pipe and pulling the new drain behind it. Interesting idea, not so sure about replacing copper service though. I think about spending all day trying to shoot a bore under regular driveway due to all the builders trash that was under the concrete. That was with the under wonder deal, water and rotating drill bit. Finally had to drop down a couple of feet and start over, then it dove four or five feet. Nightmare times on bid jobs.

Isn't the replacement of galvanized steel with copper done similarly, but maybe with a percussion tool?

pipe bursting has been around for a long time. when it works it works great, when it doesn't you have to excavate. that was funny :laugh:
many municipalities have those for the maintenance divisions

forgot the terminology - "pipe bursting" brings to mind flushing cherry bombs in school bathrooms :)
