I've got a neighbor who asked me for input concerning a waterline leak. It's isolated between the meter and where it enters the house. The problem is the waterline runs under or right beside a 3.5' diameter oak tree. We have talked about running a whole new line or trying to repair the existing one. The current line is about 30 years old. So replacing it seems to be the to do. Neither of us has used a trencher or Ditch Witch so I was wondering if the dear people on TBN could shed some advice? I have a stump bucket and a box blade where I would drop one or two scaraffs down to break up the dirt then use the stump bucket to do the majority of the clean out. Any ideas are much appreciated.
