I live in a house that is over 40 years old. There is a leak in the basement that is coming from the drain in the kitchen above. Water is coming through or under the block wall about 8 feet from the line from the kitchen. This line goes to a septic tank and appears to go through the slab.
How do I find this leak? Should I start at the drain or at the point of the leak? Is the pipe under the block wall? Thanks David
