So here is the problem. Layed a 4" PVC pipe for conduit with duct tape at each end across area where driveway would be for sprinkler pipe and wire. Created a diagram which had 2 offsets for each end of the pipe (I thought anyways). Put in the asphalt driveway. Go forward in time. Able to locate one side of the pipe and not able to locate the other. Can get a piece of funny pipe into it, and tried digging the end out close to where is should be but still can't find the end. Dug as far as could without going under driveway since don't want to undermine the driveway. Any suggestions would be appreciated.
