A sewer line owned by the Condo Association was blocked, causing the waste water from Units 55 & 56 to back up into their basements. Repeated attempts to open the sewer with a power auger were unsuccessful and a video inspection revealed that a section of the sewer lead pipe was completely separated. Kramer-Triad received approval from the Board of Directors to hire Paul C. Scott & Sons Plumbing to excavate and fix the line as soon as possible to alleviate the problem.
Once the sewer line was uncovered at the bottom of a 10 ft deep hole, the cause of the problem became evident. The contractor who made the tie-in to the sewer lead when the basement was originally excavated in 2004 must have hit the lead with their backhoe and pulled it out of the rubber friction boot on the 10 inch sewer main. This single 6 inch sewer lead services both units and it had been pulled out about 18 inches from the boot. The situation went unnoticed because that end of the sewer lead remained covered with backfill. Ever since the units were sold in 2005, all of the sanitary waste from Units 55 & 56 has had to flow through this 18 inch long tunnel in the sand in order to reach the sewer main. Eventually this tunnel collapsed and the sewer lead filled with sand. It's a wonder that this problem did not surface much sooner and that a sink hole never developed in the front lawn.

Workers excavated an 8 ft. x 15 ft. hole that was 10 ft. deep.
The worker in the hole is standing on top of where the sewer lead should have been connected to the sewer main; the manhole structure is at his side.
The section of sewer pipe between the two black Fernco flexible couplings is the permanent repair and it bridges the gap apparently created by the backhoe operator in 2004.
