Util-Locate assured me that they could "precisely" locate and determine depth of the sewer line and they failed on both counts. The technician sent out was poorly trained and unable to locate the sewer line with radar-type equipment. He then attempted to locate the sewer line by inserting a tool down a floor drain. While forcing the tool down the drain, he broke the tool in 2 places before giving up on trying to identify location of the sewer line. The next day it was determined that the floor drain was now blocked and would not drain properly. Util Locate would not take any responsibility for the damaged floor drain and and hung up on the phone when asked when they intended to follow-up on the problem their technician created. There was no problem with the floor drain before Util-Locate attempted to use the drain to locate of the sewer line. Beware of Util-Locate as their competency is lacking and and they ignore problems they have caused. I would definitely avoid using this company.
