I have to put in a new sewer line and split off from the line I share with my neighbor (new city rule).

Anyway, neighbor won't let me put seperate line across her property, so I have to either tear off a bedroom attached to my house to lay the line or tunnel UNDER the beadroom. Distance involved in the tunnelunder the room would be 20 feet.

What do you all suggest I do as far as tunneling goes? Is there some really great method to bore a hole at the right angle for 20 feet or do I just play like an old time movie prison rat and start tunneling???

I'll be laying 4" plastic/PVC if that helps on your answers.

Again ANY advice would be appreciated.
