This task will be an attempt to clear the branch line to free any debri lodged in the line. Customer has a huge belly in is 2 inch cast iron branch line. We scoped the rest of the line, the customer is opened but when too much water is pushed through the line it’s causing water to push back. Highly recommend putting in a sewer ejector pump and pit this will eliminate breaking up to 30 ft of concrete as the snaking is not going to do anything to help the issue.
