Ok, great. I put into the septic field instead.
The next problem is the porch, which is a large block of concrete that has already separated, cracked away form the house foundations due to water damage. It is still fairly level. Would you try to slide the pipe through the soil bellow the porch or go all the way around? Same with the down spouts. It's about 6' width.
I guess hammer a 2x4 through to the other side, or no weeping tile. I can't water proof the wall at this point... or maybe carefully clean out 2" from the wall and at least slide in some plastic dimple..?
