I have a home built in the 40's. It does not have a sump pump. In the middle of the floor where there are some long cracks, I get seepage after heavy rains, not a ton but still. If I installed a sump pump, could I just run a drainage line across the middle of the foundation floor back to the sump pump, instead of going all the way around the perimeter of the basement? Most of the basement walls are half finished or framed.
