I don't know if this is the correct name for this pipe, but it is a big, black plastic pipe that ends up in the basement and goes under the concrete. There is a round disc on the side of the pipe and it is tight so I pretty sure the water is not coming from there. It is not a lot of water - more a weep but enough to make the carpet around it in our finished basement wet - i wonder if it is the connection that is not good. We did have a problem earlier this fall where the basement was wet coming in from the exterior wall. The carry-away pipe on the outside drain pipe had come off and we had had a lot of rain. I don't think this the same issue. Any help would be appreciated ....cash is tight.
