We have a 40 year old property which had lines put under parking lot of faciilty back then between elevator room and one of the elevators. There is a break in the line somewhere under there. Is there an easy way to fish anything through there to run a new line or is rerunning the line overhead (80 hours) the best option. Thanks for your help! I am unsure as to the type of underground method that was used 40 years ago, but maybe someone remembers the standard. This is in the panhandle of Florida.
