Customer needs estimate for installation of 6” backflow for fire system. Due to not knowing which direction the lines runs or depth of line it is difficult to provide accurate estimate to perform work. In order to provide accurate estimate we will need to dig and expose the fire line to determine path of travel, material of pipe, as well as o determine what connection, if any we will need to re establish. Once we know these things we can provide a more accurate estimate for installation of backflow. After exposing line we found that the fire line runs under the sidewalk at an angle almost parallel to the existing vault. Line is approximately 3’ deep
