This happened earlier this year to a neighbor. The leak was where the black plastic line from out in the lake was mated to a steel pipe nipple where the transition was made from plastic to all steel into the crawl space/pump. The plastic had been (I think) heated at some time to soften it to fit over the pipe nipple. At some point, caulk was applied to this joint. Visible leakage at this connection was seen, indicating failure of the connection.
