I have a drilled well (132 ft) about 50' from the house. The water line runs into the basement through a hole in the foundation wall about 9" above the floor. Four inches above that there is a second hole through which runs a plastic conduit with 3 wires to power the pump. There is also a diagonal surface to floor crack in the concrete which is due to a bad drainage problem that has been corrected. A few years ago, I thought the crack was leaking and I filled it with waterplug, also filling in around the water pipe and wires.
Lately, there has been water over in that corner, although there hasn't been any rain, and close inspection showed it was coming from near the water pipe and wires. Today, I chiseled away all the waterplug to get a good look at what was going on....expecting a leak in the water line. To my surprise, the water is coming from inside the plastic conduit containing the wires to the pump. I've cleaned and dried the area, and there is no doubt...the water is in the electric conduit. For the time being, I've stuffed some cloth into the conduit around the wires, and now the floor is staying dry. I can visualize some ways to plug the conduit with some sort of quick curing sealant (suggestions welcome) but the thing that worries me is why there is water in the conduit. Has anybody seen this before?
