And as far as drains in basement, only one that is a standing pipe in laundry room. it stands vertical about 2.5 feet tall. I have been draining washer into it with no probs so far. I'm guessing it drops into weeping drain system. The basement is on grade(to right of pic) and has an asphalt slab out the door. I dug into it for a post at one time and found a layer of 1 inch rock under it, the rock layer seemed to be about 2 feet deep.
