We live in a 9 year old three story town home. We recently noticed that the main 4" sewer drain that carries the waste water from the top floor toilets, showers, and washing machine has sprung a leak just above a 90 degree elbow joint down on the main floor, just prior to the point where this pipe enters into the main sewer exit line for the entire house. When we flush a toilet, we get a couple of tablespoons of water from the leak. When the washing machine drains, we get about a cup full. We did not notice the problem until just recently,but it could have existed for some time because it was hidden by ceiling drywall. We've now cut away enough drywall to see where the leak is occurring and access the leaking joint.
Is there a code-approved method of patching a leaking joint in a drain line? There is little internal pressure in the line. I have seen some rubber clamp-on collars at the big box stores. Would one of those be acceptable for a repair?
