I have a 4 level backsplit. On the lower 4th level which is the basement, I have a sump pump on the left side of the wall near the front of the house. On the right side of the basement also at the front of the house, is a cold room. In the cold room, there is a hole in the floor. This is approximately 1 ft x 1 ft square (could be a bit larger) In the hole you can see clear water and gravel as well as a drain pipe ( the pipe is capped). The hole is covered by a sheet of wood to fit exactly over the hole. Can anyone tell me what this is for and where would the water be coming from? When I lifted the board too see what this hole was, the board was quite wet and rotting on the underside.
The hole in which you are talking about is more than likely your main sewer line running to the street. You need access to this and this is usually where we put these types of things. As for the water in there, for the most part is normal, which is why there is clear stone underneath your basement floor slab to allow for drainage. The water is nothing to worry about, providing it is not seeping up through your floor and is being drained away. If there is constant water in there you may have an issue with your weeping tile. Keep an eye on it and see if it disappears, if not, you may want to have your weeping tile checked to see if it is working properly. But like I said, if it is not seeping up through your floor, than I would not worry about it.
