We have an uncapped old sewer line in our basement that was walled in by the previous owners. We only know this because when we had a plumber out to snake our sewer line (for tree roots), they accidentally sent the snake in the wrong way and managed to pull out some insulation. When they sent the camera in to look we found a pipe filled with insulation and when he pushed the camera farther through we were looking at 2x4's and walls. We know basically where the problem is but it will require tearing out walls in my downstairs finished bathroom.
My question is, once I find the uncapped pipe, can I just put a regular pipe cap on it or do I need some special cap to keep the sewer gases from building up? Thanks for any help!
