I have a 1" black plastic pipe coming into my basement from my deep well. It comes through a hole the poured concrete wall and shares the hole with the well power cable. The hole is sealed with what looks like mortar. I get a fair drip-drip-drip leak during the early spring melt (like now) every year and, occassionally, during a summer deluge. Right now I'm getting about 5 gallons every 6 hours.

Can any of you good folks in the CBN brain trust suggest how I might go about patching such a leak? Is there anything I can do from inside the basement, or, must I (ugh) excavate the outside of the wall? Thanks for any help!
