I get what you are saying. How thick is the slab in a basement typically? I am guessing that this is just moisture moving its way up through the floor rather than the water level since I have the level in the sump set below the floor. I will try lowering the turn on level some more and see...

They do a number of things...similar to how a payphone works....first, most machines run the coins through a magnetic field (to pull metal slugs out). Then they are tested for weight and size...

Yeah, the house is at least 35 years old...I have very little details about the construction of the home. I am assuming that the french drain was added after the house was built since it does not span throughout the entire basement (it's only at the front of the house in the basement where...

I understand what the sump pump is doing...the reason why I ask is because I have heard several (qualified) people tell me that this is a good suggestion. I do not claim to be an expert on cement dynamics, but I can see where having a smooth cement surface (i.e., the smooth, flat, square sump)...
